Learning frustrations of an SAP Developer
SAP Ecosystem is becoming more and more complex for developers with the introduction of S/4 HANA and Cloud offerings. They have released a lot of new technologies e.g., SAPUI5, CDS Views, ABAP Programming Model for FIORI, ABAP RAP, CAP, SAP BTP, etc. It takes quite some time to acquire that knowledge and become proficient (as with everything) but I think the learning process could be smoother if better real life demo examples (source code) could be provided for each technology.
The learning material is all over the place (SAP Learning Hub, SAP Press Books, Official SAP Help, openSAP courses, Blogs, Tutorials and the most recent https://learning.sap.com/). Some courses are better than the others, but are hardly complete, hence you have to go through the material from all these different learning platforms and connect the dots. But even then, you find out this is not enough and you are still missing a puzzle or two to deliver your solution.
It was different back in the day when I was learning ABAP as a graduate. I had a lot of experienced people around me, I could just turn my head and ask a question. With the new technologies this is not the case, unless you are lucky enough to work along some passionate people that already have the knowledge in a field you are trying to master. The SAP Community Network forums are not as active as they used to be, so it is hard to get any help there as well.
I remember when I was first learning SAPUI5 about 7 years ago. I spent countless hours to figure out how to do a deep insert as all the official SAP demo apps and documentation were showing a basic example of a single entity, not a parent-child relationship. Then I spent another good chunk of time to figure out how to do OData batch processing as there was no examples, nothing in the GW100 book or the SAP Press book on how to do it end to end. Just a brief mention that it is a thing. After all I digged out and reverse engineered standard SAP’s SEGW service. And also before the introduction of SAP WEB IDE and it’s ‘kick start’ templates, people had not clue how to structure the app and I saw a lot of messy code.
Now I am learning the ABAP Programming Model for FIORI (as the system is not up to date to use ABAP RAP). And again, the official documentation only gives an example of app with custom tables, where I really want to develop an app with NON GUID keys, calling a BAPI to post data to standard tables. Neither the official documentation nor the learning hub material talk about the /bobf/if_frw_draft~copy_draft_to_active_entity method to use for calling a BAPI. So, you either have to reverse engineer standard FIORI apps (which takes a lot of time) or hope that someone has already done it for you and documented (which thankfully has been done and must have taken a lot of time and effort). And FIORI Elements is another technology where all the information is spread across different websites, without a single source of truth.
This is all not a rocket science. Once you figure out how to do it, then it becomes really easy. The pain here lies in finding the relevant information on how to achieve something that is not described in the official documents.
The bottom line is that we have to deliver real world solutions which are more complex than all these “develop SAPUI5 app in 5 minutes” or using the famous Flight data model. We also work under time pressure as per estimates and don’t really have time to dive into standard SAP code for a few days to figure out how to do stuff.
All these learning platforms mentioned above are great to get the basic understanding. You even get hands on exercises with openSAP, but this is not always enough. I would like to see SAP to provide use with comprehensive demo programs/apps for more complex scenarios, showcasing all possible features of given technology. Example – a real life end to end SAPUI5/FIORI app scenario calling a BAPI, using on of the recent programming models accompanied by a documentation with source code available on Github, providing as a reference on ‘how tos’ and ‘best practices’.
I think if SAP wants developers to embrace the new technologies, they have to make the learning process quicker. No developers with new skills = no adoption of new technologies by companies.
I am curious to see if other people are having the same frustrations, or should I change my learning approach? Or am I asking for too much and trying to create an utopian developer world?
Fully agree. We need real life tutorials based on sales / purchase orders materials etc to start with instead of made up examples.
Well, pure ABAP skills are of little value in real life projects. What counts is to know how to use ABAP within the context of SAP standard functions - how to get required data, how to enhance standard processes. Very rarely are substantial ABAP developments build from scratch. The point of buying an out-of-the-box system like SAP S/4HANA is to use its standard functions, not to develop them during an implementation project.
That's why I don't really like the segregation between functional and technical (ABAP) consultants. The best ones merge those two realms.
You raise a very important topic. Thank you for your critical words in this context. In my job, I am very busy with the subject of training, further education and studies. So here is my impression:
Getting started with many topics is not trivial. If you have no experience with SAP software and the many learning opportunities (and probably less time), you will quickly lose yourself.
Furthermore, from a technology point: It's often very difficult to choose from 3 possible solutions for the implementation of a requirement. 2 possible solutions are outdated, only one possible solution is state of the art. It's precisely this dilemma that my students encounter again and again. Building understanding in an technology environment that has grown over time (maybe 40 years) is so tedious.
Accordingly, I see more and more the problem that one either only masters the current technology or mainly only the old technology. The connection to the actual business process is often only there with older colleagues. Many younger colleagues are overwhelmed by the technology alone. Then the sense and purpose of programming is quickly lost. Basically, it's not about programming (even if it's a lot of fun), it's about supporting business processes.
... I could write here for hours, but yes: We have to make SAP software accessible for future generations. Otherwise it becomes a COBOL issue.
Jelena Perfiljeva, Michelle Crapo; Enno Wulff, Sandra Rossi and all the other brave SAP community members: Your opinion on this topic?
Thank you Michael for your comment. My main issue is to shorten the path from learning the basics of a given technology to being able to deliver a productive solution (which is quite important in current dynamic world, and a new technology being introduced every year). Let's take for example FIORI Elements + ABAP Programming Model For Fiori. I can learn the basics from the SAP Help and the Learning Hub. And with the access to S/4 HANA system I can take for example 'Manage Purchase Orders' FIORI app, reverse engineer it and debug it to see how stuff gets done, as the scope of the functionality of this app goes far beyond what is in the learning material. And I can use the findings to create my own solution. I am not saying this is impossible I am just saying it takes a lot of time to learn through reverse engineering, especially when new to the technology. This could be solved by providing more comprehensive Tutorials/demo apps with documentation describing how to go about more advanced things. I think SAPUI5 documentation has come a long way and is quite good although in the demo apps there could be a template for freestyle CRUD app with header->item relationship.
Long story short - this issue could be solved by a step-by-step tutorials on how to create a complex real life app like the 'Manage Purhase Order' with the source code of both front end and backend available in Github for reference. Reading such tutorial, would really speed things up. I really like this style of tutorials: https://github.com/SAP-samples/abap-platform-rap-opensap. But again, this is giving you a basic overview again. What if you want to upload a file using RAP? You have to again hope that someone has written a blog, or try to find standard SAP app to see how it is done, or try to come up with your own solution - which again, takes a lot of time.
Hello, I'm new to all this technologies. Where can I find the tutorials for the same? Can you please help me out with this, it will be really helpful for me.
As requested: my 2 cents... 🙂
IMHO the SAP world has created a maximum complex environment in a very short period. I am totally overstrained by the huge amount of techniques that came up the last 5 years. And all techniques are entangled somehow, but I could not say which belongs to what and requires which underlaying architecture.
I think SAP is doing the best they can by offering a lots of OpenSAP courses, documentation and a lot of engaged people promoting things.
My main issue is to shorten the path from learning the basics of a given technology to being able to deliver a productive solution
Productive solutions often are huge and complicated and need to cover a lot of requirements. Therefor I think it might not be constructive to build and document a complete productive application. And even when: this application will not fit the needs of your solution. So all parts needed in your special case can only be parts of many different techniques, settings and best-practices.
Things will be and stay complicated. As far as I am right with this statement you will have to fight yourself through the jungle of techniques.
By the way: I am impressed by the way your have described, Radoslaw, ! And in my opinion this is the only way to go: have a requirement and learn bit by bit was is needed for this solution. 👍
btw: Often enough I experienced that SAP itself didn't have the solution for problems that I thought should be a common problem. There are still companies that print their forms with SAP-Script. Not because they were not capable of using new technologies but because it's the fastest technology. If you need to print thousands of forms in two days Adobe Forms might not be the best solution.
I for myself try to keep eyes on what is going around the SAP universe loosely. If there is the need to learn something special I try to go on with it. Piece by piece.
Also we know from experience how many technologies (Web Dynpro, BSP pages etc.) ended up. So I have very low expectations from all these new ones. To be honest...
I agree with Radoslaw and I've observed the same thing myself many times: you get the examples for very simple scenarios but it's not really what ABAPers need for actual work that we do.
What developers need is a cookbook. You want to do X? Here is a code example. And I totally understand that it may not be a "blindly copy-paste into client's system" example, but I think most of us are smart enough to adapt samples to real-life use cases.
For example, we've already started developing using ABAP RAP, so I'm always on the lookout for any content on it. And I can't tell you how many times I've already seen the same exact slides, the same examples. We have seen so many "RAP introduction" presentations, where is "now that you've already met RAP, let's get to know it better"? In the real project, I do not need to just update a Z table to create a booking. I need to update a sales contract using same old poorly documented BAPI and to download a document stored in DMS, Where are examples for that?
If it would be a "blindly copy-paste into client's system"-example, you could maybe automate it = welcome to templates 🙂
By the way: There was once a great ALV guide as "SDN Community Contribution" with a lot of examples. That document saved my life more than once. Whis there would be something like this document for Fiori Element List Report.
There is a package SABAPDEMOS if I remember correctly. And it has tons of ALV examples that you can copy bits of code and adapt. That's what we need for the new technologies.
Exactly! Calling a BAPI, uploading/downloading files whether it is GOS or DMS are common scenarios we do most of the time. These are not outlier scenarios that SAP can't find time to cover in learning/examples. Neptune Software for SAPUI5 development may be disliked by a lot of people (it has its pros and cons) but they actually had good documentation, a library of examples for common scenarios (e.g. GOS attachments) and very good support (forums) and if you still struggled with an issue they would put you through to one of their developers to help you out. That's why they got successful and grew. But obviously they were a start-up just a few years ago so they had to care and go above and beyond to attract customers and developers. SAP is at a different stage. They already have loads of customers married to them so they don't really care. But SAP's prime time may not last forever just like Nokia's or Kodak's haven't. If they keep making life difficult to developers, they will start switching to different technologies like Azure that I suppose has much better learning resources and community as it is not as niche as SAP. I really enjoy learning new technologies, but not if the learning process is painful and takes a lot of time due to limited resources.
I partly agree. As you mentioned at the top of your post technologies change quickly and new technologies arise quicker and quicker. I think that it is important for SAP to support all these new technologies to open the SAP ecosystem to a wide range of (young) developers.
Cause there are so many technologies it's hard to write and maintain a real life example for each of them, even when it is just published. Reality also shows that customers adopt those new technologies very slowly.
So at the beginning the learning curve is steaper than after some time.
My suggestion is to blog your findings and reveal your learning projects to the public. I think SAP customers should do more community work and see the benefit of it. Currently a lot of customers think that SAP has to deliver everything to them and also just in time.
I see that SAP is eager to do a lot of support and they write a lot of tutorials and sample applications. With openSAP and learning.sap.com they also made and make learning SAP technology easier than it was in the past.
To summarize the before said I shout out:
SAP CUSTOMERS DON'T SIT ON YOUR KNOWLEDGE CAUSE IT'S OUTDATED SOONER AS YOU HAVE SPREAD IT EVEN TO YOUR OWN DEVELOPERS. SO SHARE IT AND BENEFIT FROM THE KNOWLEDGE OF THE COMMUNITY.
Support for your shouting 🙂
Thanks for your blog post, Radoslav!
For me, things start getting complicated even earlier, namely with placing all the various technologies and solutions where they possibly belong and how they relate to each other. With all the available options, how do you decide which one will be the best to use for your project and what all do you need to pull it off? After last year's TechEd I tried to order my thoughts by writing a blog post Trying to stop the spinning of terms in my head. It's a little bit clearer now for me but still a work in progress.
good point but as business processes get more complex also technologies get more complex. There is no single way to solve a problem today as there was years or decades ago.
Cause there are much more stakeholders involved today a wide range of technologies can be used and is used to solve problems. So projects need architects who have an overview of these technologies, of the know-how of the workforce and know about the strategy a company pursues.
Personally, I am a bit surprised that SAP customers stick to ABAP technology to such a high degree. Of course, ABAP and the ecosystem are evolving, but in my opinion it cannot keep up with all the other technologies.
To be competitive in the long term, you have to be able to act quickly. This is (in my opinion) much better possible in the non-ABAP ecosystems Kubernetes and Cloud Foundry. In addition, you can get all the excellent architects and developers on board who have been working with these technologies outside the SAP world for years and successfully already implemented large-scale projects.
Hi Radoslaw, ,
I agree completely with your frustrations. I am currently trying to get familiar with developing in the BTP environment and even though some of the tutorials are very good(see learning.sap.com) I find like you the tutorials cover only very simple use cases.
When I first joined SAP, I was working in the PDI area learning ABSL. As is now, the tutorials covered simple topics only. The difference I would say back then is there was a very active sap blog community posting Q&A and some very dedicated developers who wrote countless blogs to help share the knowledge they had gained. I also had a really experienced mentor who was invaluable to me gaining knowledge.
I think the idea of building an active community is where we could all improve. Maybe SAP could even give people incentive's to write blogs and share the knowledge they have gained. #BuildBridgesNotSilos
Does it mean, that you, working as an SAP employee, don't have access to BTP subject matter experts (within the company) to ask them questions? If it is true, and there is no knowledge sharing between SAP employees, then us, 3rd party developers can't count for better times!
wholeheartedly agree with a lot what is already said here. Although SAP makes great strides with getting their house in order (like learning.sap.com, api.sap.com, opensap etc.) there still seems a game of hide&seek.
For me as a Functional/technical consultant i want to take the example for S/4HANA Cloud public edition for example where the community is actually a closed community and there is a restricted access. Why hide all that knowledge how to use SAP the best?
And as commented elsewhere above, SAP should blog the real-life requirements and solutions here and more actively contribute and moderate blog.sap.com
Thumbs up to all contributors here!
Some times the underlying technology stack of the systems drives what technologies we need to learn for enhancing business processes in these systems.
For example, some things i can think of
For S/4HANA (on-prem):
ABAP + CDS, Modelling, latest advancements in S/4HANA extensions, Fiori, SAPUI5 apps and extensions, CPI middleware
This has a world of services that caters to basically anything we can imagine
SAP has really done a great job in SAP BTP area to give comprehensive use cases and reference architectures to follow for implementing projects on SAP BTP. Below is a great resource.
From SAP, I would like to see the same on S/4HANA technology enhancements. It is good to have best practice implementations and reference projects using the latest technologies for some complex business use cases of what these latest technologies are capable of, what are the best practices SAP recommend, what are the limitations if any.
Honestly I don't see the point of RAP and even less ABAP Cloud.
The main problem that SAP has right now is "Jack of all trades, master of none" they opened the door and released the kraken ! an uncontrollable beast.
Advanced Business Application Programming (The idea was to have a high level programming language to focus at the business level and not so much technical)
You have so many different things to do the same things, lots of services being deprecated and also even in different technologies because SAP buys products rename them and there you go... Like SAP C4C, SAP CAI or SAP iRPA... and now Appgyver.
Instead of going rogue with RAP and ABAP Cloud I don't know why they didn't enhanced BSP. I mean when you deploy a SAPUI5 on premises it's even "like" a BSP, I know that I'm old school. But I really liked the BSP concept and use it kinda like PHP with ABAP code embedded, that is something clear and easy to understand as an ABAPer
I'm really looking forward and hoping that Appgyver works well because I really hate "web development" and I think that low/no code could be work awesome with SAP.
I'm just ranting
ABAP originally stood for "Allgemeiner Berichtsablauf Prozessor" what can be translated to "Unique Report Running Processor", nothing with business. It was just ment to create reports from database content.
I thought it was original "Anfänger Basteln an Programmen" (Beginners tinker on programs)
Yeah, unless AppGyver let's you build apps that look exactly like FIORI apps, it may not gain as much traction.
"I know that I'm old school ... that is something clear and easy to understand as an ABAPer"
This is the point. Young developers and even a lot of older developers, like me, don't want to use ABAP. The time will come when you have retired. Then there must be also people who can develop business applications in SAP systems.
I see your point but there are still companies using COBOL or even AS/400 so, yeahh eventually ABAP will die, regading the teaching subject the thing is that without a SAP system there is no point in using ABAP.
The problem that I see is that SAP users still prefer SAP GUI over SAP Fiori Launchad and it breaks my heart but if I have to be honest the SAP Fiori Lanchpad UX design is awful.
Excuse me but there are some errors and some misunderstandings in your last post.
Furthermore SAPUI5 has more (in count) and more feature rich UI components that simply fit together than other frameworks.
It's hard for SAP ecosystem as a whole to transition to open source. In old days you spent $2500 for a week for all important SAP learning courses. Your best option was an SAP manual from that training session. There were informal demo examples for how to do basic stuff in the system. But the core knowledge about architecture of the data dictionary or Function Modules that could manipulate them was all proprietary. Enhancing SAP application was primitive and Project managers discouraged and hence custom new solutions had to be built. SAP now owns the whole stack (Database + Application). SAP is also transitioning as a cloud company. At the same time there are these on premise SAP systems that are transitioning to hybrid cloud solutions. SAP's client (frontend) used to be a Windows based SAP GUI. Now it is the browser. That impacted the SDK environment as well SAP application. SAP also consolidated Analytical system technology into its transactional technology. Since now SAP also owns the database stack (HANA) it is pushing solutions at the database layer from the application layer. SAP is also delivering solutions to the Mobile client for both on Premise systems and Cloud systems. The result is a complete CHAOS as far as learning new technologies for SAP veterans consultants. Don't even get me started on the re-engineering of the ECC functionality with S4/HANA.
An application that has undergone changes to it's database stack, application stack, infrastructure stack as well as functionality stack, puts a tremendous toll on veteran SAP consultants as far as learning is considered.
SAP is also facing a new competition to it's existing supply chain solutions. The evolution of AI technology with it's earnings power tied to the CRM solutions for it's competitors is a growing threat. Sales and Order generation is being heavily influenced by AI technology.
SAP should invent new type of training for technology consultants.
The idea should be imagining scenario based training solution for technology consultants.
For e.g a typical scenario could be how to convert legacy master data into SAP system. SAP's training should teach how to do that using best practice.
Another scenario could be how to extend an existing SAP application screen for enhancing a data entry changes to resolve a custom functionality expectation.
Another scenario could be how to process files as batch data processing for posting transactions into SAP.
Another scenario could be how to process transaction as interface in near real time
How to develop a custom report that can be delivered to a mobile client and a desktop client as one solution.
How to build a custom transactional solution to gather data from an end user and integrate it with a SAP application Module. How to save data using best practice for locking tables before data can be saved.
With a scenario specific learning approach new developers as well as existing experienced consultants can quickly adapt to latest technological changes that are happening at a rapid pace.
Thanks for writing this, Kiran! This is an excellent insight. I think your idea of "scenario-based" education is brilliant but, sadly, I doubt SAP will use it. From what I'm seeing, there is a strategic problem that the goals of SAP's supported education (such as openSAP or what's on Developers site) are just not the same as the learning goals of the actual SAP developers, especially the veterans.
This problem always existed but I feel it got exacerbated in the recent years by de facto loss of SCN and reorganization of the SAP Mentor program.
Let's not loose hope and hope that SAP Gods are listening to our conversation 🙂 .
Once SAP focuses on an issue, time and time it has shown capacity to solve problems. No wonder best organizations in the whole world (both government and commercial) are using SAP and THEY WILL ENDURE THE PAIN OF MOVING TO S/4 HANA.
If SAP can realize that learning and adapting is an issue for the SAP Ecosystem as a whole I am sure they will do something about it. Let's raise this as an issue in every forum that we can,
Loss of SCN was overwhelming for me too. I think as experience SAP consultants we should demand more online delta learning courses to fulfill the gap.
In the 24 Hrs connected world if we have short videos or long videos coupled by just in time access to a training system that covers scenario based teaching, man oh man, that could revolutionize training as we know it...
Just imagine you are at an airport or a train station and you pull in a certain training scenario that your are interested and you get the sufficient knowledge and this all happens right before that import client brain storming session that was schedule to solve a complex problem. Just imagine how much productivity that could revolutionize. And then imagine a SCN type community just around these problem solving sessions where people can share how they provided a solution for that same issue and how different it was and how client specific it was...
THIS WILL BCOOL WAY OF DELIVERING SOLUTIONS...
Thank you for writing this post and sharing your thoughts about scenario based training !
Technologies and solutions keep evolving, SAP Learning is currently re-inventing the education platform in order to provide all our learners a better learning experience with relevant content (based on levels of expertise) which can be consumable in an easier format.
Coming from SAP Product Learning, from what I know scenario based approach has been a major focus when it comes to developing training content. Take the course S4D425 (Extensibility for SAP S/4HANA) as an example, this course covers the different extensibility approaches for SAP S/4HANA that are available to customers and partners using a scenario perspective. We cover In-app extensibility with a focus on adaptations created by key users that have deep business knowledge but no technical expertise. One can also learn from this training how to enable custom database fields for usage in SAP Fiori applications. Learners coming from different background and expertise will definitely benefit from this kind of training.
As a developer, you are probably very interested to find out more about our latest training offerings. We are currently building a training about the data migration cockpit and this will be published soon on the new learning platform learning.sap.com . From a scenario based perspective, learners can see how to migrate different types of master data (e.g. cost centers, customers,…etc.).
Stay tuned for more developer trainings coming up in the area of SAP BTP, ABAP environment, as well as in HANA and HANA Cloud.
SAP has such a comprehensive portfolio, we are gathering inputs and feedback continuously from learners of this community, as well as from the SAP Mentors group and the SAP Champions. We are striving to provide all learners with the training content that they’ll need as we all grow together.
Thank you Alice Chang for your comment and I am happy to see that someone from SAP would take the feedback gathered here (not just mine but others as well) into account.
SAP needs to be more developer friendly, mainly in terms of good documentation and code based (real life) examples, if its goal is to retain current and attract new talent.
I am aware of learning.sap.com and I think it is a really good change in terms of learning experience. Something I saw before from Microsoft and wished SAP did something similar, and here we go, SAP has listened. But again these courses are a good introduction to the subject, but on the job we also need to have access to great documentation, best practices and code samples.
E.g. I have been trying to learn RAP, did the openSAP course, read the SAP help documentation, but I still have no idea how to built unmanaged, draft enabled app, with sales order->sales order item relationship, calling a legacy BAPI. Something like that slows down the adoption of new tech.
I am not sure if I have missed it in the comments. But I think there is another important or challenge from an ABAP developer perspective. Even if we(mane of ABAP developers) put significant effort to learn a new technology by reading through materials, watching demo sessions and practicing with most simplified data models, the learning fades away overtime due to the fact that either most of the customers are still not using the new technologies offered by SAP or not everyone is getting an opportunity to work on these areas in real time project. This is most painful to me.
This might not be applicable to many of you. But believe me, lot of us are facing this challenge and I have quite a few friends among this lot.
I can understand what you are talking about.. but I also see that I get the basic understanding (as you also mention) from the content SAP provides.
So converting this understanding into real world business cases and of course earning money with it I see as my job / passion..
If you want more help SAP is offering a lot of trainings and yes, of course, they earn money with it.
Sometimes I just would have more crossreferences.. so where can I read exactly this in the documentation.. not only the tutorial content.
So if you ask me as an developer.. of course I would love to have more.. ask me as an employee I can fully understand the strategy SAP is offering..
Just going to put this out there as an improbable, but worth pondering idea:
Wouldn't it be nice if SAP did a living tutorial that was branched in git per ABAP release (and any fixes backported where required - which we could subscribe to) which did the following:
a) Started with a UI design, and put together a high level specification
b) Built an unmanaged RAP object with a many to many to many draft relationship included (non-trivial data model in other words) like a pretend Purchase Orders, with Line Items that have multiple sub-line items.
c) Build with create, edit, draft and an data model action like "Approve" that combines multiple fields in validation (for demonstrating the UI error handling).
d) Creates a projection with an additional projection specific action
e) Create another projection almost identical, but demonstrate why you would create 2 projections in this example
f) Create a Fiori Elements Analytical List Page of the first projection using Odata v2 with non-trivial value helps, and maybe some analytical behaviour like aggregation over time per Fiscal Year.
g) Create a Freestyle Fiori app (built using TypeScript) using the second project and Odata v4, demonstrating how to manage deep updates and draft handling when not using Fiori Elements.
And with all of the above, they use good naming standards, apply and explain tricks/tips such as grouping things better (like unique packages for all new RAP services), included production ready error handling, assume developers are comfortable with 6.20 ABAP, but not 7.5 ABAP, and maybe even include how they designed this from the very beginning.
Obviously - this would have to be done by the UI5/RAP team as a significant project and managed by interns in the team ongoing with support when major features are released - but I think they would benefit from going down the path of every consultant asked to do this...
Of course - This could be a great video series to tune into each week where they give the key team and a good facilitator who can ask "why" regularly, the challenge of coding this on the fly - Spending 2 hours total per week to progress this to the end but to customer production level standard - no shortcuts?
Ah - To dream.
Thanks for starting the discussion Radoslaw!
That would be a dream what you just described.
All we need is reference apps, something like the FIORI EPM reference apps. Back in the day when SAP WEB IDE was a thing, these reference apps were released for SAPUI5: https://blogs.sap.com/2014/11/24/fiori-reference-apps/ , which helped me a lot to understand how to structure the code etc. And you can also check the back end code in your system if you were on the relevant patch level.
Unfortunately they are not available as part of SAP Business Application studio or at least I couldn't find them.
