Fiori CRUD End to End Scenario

     There are many Fiori CRUD scenario implementations. How this one is different from others? It is based on SAP Template and represent best development practises. Besides of, it covers creation of CRUD OData Service and provides insight of what happens at back-end.

To begin with, create CRUD OData Service following Chandra Mahajan’s instructions in his blog. Please make a small change to ZUSERINFO_SRV ODataService to enable WebIDE template to see UserCollection Entity Set:

CRUD End to End 1.jpg

Note: if you do not have access to gateway system, then you can use cloud trial system as described in my blog.

 

Once CRUD OData Service is ready, proceed with Fiori application creation.

In HCP Cockpit create destination pointing to your gateway system (in my case it is ABAP 7.40 cloud trial system):

CRUD End to End 2.jpg

Then in WebIDE from menu choose File -> New -> Project from Template

CRUD End to End 3.jpg

Select SAP Fiori Application from Category drop down

CRUD End to End 4.jpg

Select CRUD Master-Detail Application template and click Next

CRUD End to End 5.jpg

Provide Basic Information and click on Next

CRUD End to End 6.jpg

Select you destination from drop down (NPL in my case)

CRUD End to End 7.jpg

Select ZUSERINFO_SRV from services drop down and click Next

CRUD End to End 8.jpg

Customize template as follows and click on Next

CRUD End to End 9.jpg

Click on Finish to complete project genetation

CRUD End to End 10.jpg

Note: generated Fiori application scope of functionality depends on DataService. Try to explore CRUD template with other services as well.

 

Run generated CRUD Fiori application

CRUD End to End 11.jpg


As you can see Query operation works providing a list of Users.

CRUD End to End 12.jpg

Click on Add button to test Create operation

CRUD End to End 13.jpg

Provide enter user details and press Save

CRUD End to End 14.jpg

Select just added entry and click Edit to test Update operation

CRUD End to End 15.jpg

Make changes and press Save

CRUD End to End 16.jpg

Finally test Delete Operation selecting the entry from master list and clicking Delete

CRUD End to End 17.jpg

Play with you generated Fiori CRUD application and explore it.

 

You can check data at back-end at any time in ZUSERINFO table.

CRUD End to End 19.jpg

You can also explore ZUSERINFO_SRV Data Service setting external break-points in OData Service implementation class. So during Fiori application execution it will take you in ABAP Debugger session.

CRUD End to End 20.jpg

Play with you back-end service enhancing it, for example, adding error handling for creation of duplicate entries.

CRUD End to End 21.jpg

Now if duplicated user entry is added, then Fiori provides a meaningful message

      Hi Uladzislau Pralat

      thanks for your great tutorial 🙂

      I already follow all of your steps but,

      when I try to create a new entity or edit entity all of my forms always

      in not editable state.

      So I can't fill my form.

      Do you have any idea why I'm facing this problem?

      Kind Regards

      Firmansyah

      Hi Hidayat,

      have you tested your ZUSERINFO_SRV OData Service in Gateway Client (trx. /IWFND/GW_CLIENT) with POST and PUT methods (e.g. create and update records).

      Hi Uladzislau Pralat

      I already solved my problem 🙂

      My input form properties (in create view) is in enabled="false" state by default.

      So, after I change this properties to "true" my apps works well for create and update .

      Hi Firmansyah,

      thank you for sharing your experience. The template get this enabled="false" property from OData Service definition (same as it requires entity set to be addressable see first image on my blog). You can play with properties of  OData Service and figure out what makes the template to generate enabled="false".

      Hi Uladzislau,

      Thanks for the tutorial. It is helpful as step 2 after Chandra Mahajan's step by step blog . Can you please share steps to configure a tile for this app after deploying it?

      I found some blogs about configuring apps but they don't seem apt for this example.

      Regards,

      S

      Hi S. vyas,

      I was thinking to extend this tutorial up to Fiori launch Pad configuration, but unfortunately I do not have access to system SAP UI5 1.30  which Fiori Template requires. When I deployed to my system I have access to Fiori runs into error. It is too new version.

      Hi Abhihsek

      Use the T-code: SICF and execute it.

      follow the path defaulthost/sap/opu/odata/

      right click odata and choose test services you will find the URL in your browser.

      With Regards

      Hello Meera Vaishali,

      When i test the odata it is giving me error The server has not found any resource matching the Data Services Request URI

      I took the same host name and port to create a destination with authentication but connection test is not successful.

      Thanks for your suggestion.

      Thanks,

      I think, Request URI in Gateway Client is incorrect. Please provide screenshot.

      Hi Abhishek,

      please make sure that Gateway is active and alias is assigned (this is what I had to configure in my system to make it work)

      Hi Uladzislau,

      I checked in my system. Gateway is active and alias is maintained.

      In your example you said you have ABAP 7.40 cloud trial system.

      I have normal SAP system with SAP_GWFND Component.

      Hi Everyone,

      Can we do similar App on SAP BW ?

      Our requirement is to get user inputs via excel uploads from desktop and manual CRUDS  and save them in BW for reporting purpose.

      If anyone has done this ( Fiori Apps on BW) please share your experience or elements required for it.

      Thanks in advance as this will be very helpful for us as we are very new to FIORI

      Hi Mukesh,

      any BW 7.4 and higher has built in Gateway and SAP UI5. You can definitely create Fiori Apps in BW. In one of my projects I used Fiori VizFrame and Fiori Launchpad Dynamic Tiles to create KPI Tiles similar to S/4 HANA KPI Tiles.

      Hi Uladzislau Pralat

      thanks for sharing such a great tutorial.

      I am following all your steps but,when I create a new fiori application it's showing wrong values instead of exact values which i have in my gateway system. But when I check the ODATA service i am getting proper values.

       

      Can you please help me to resolve this.

       

      Regards

      Hi Nagamani,

      only I can think of is that you run the app with mock data.
