SAP Fiori Elements using RAP Model
About 2.5 years ago when I published a blog post about SAP Fiori Elements using CAP Model. Since then, I’ve been doing projects that make use of CAP framework almost exclusively, but not until recently when I started using RAP for official projects. On that note, I thought that it would be good to finally create my own RAP sample project using the same formula I used in my SAP Fiori Elements using CAP Model sample project — hence, this is what this blog post is all about!
Here’s a screenshot of the Fiori Elements App using Flexible Column Layout:
The Goal: No-Code Challenge
The Demo Project
The demo project is available in BTP ABAP Trial under the package
ZRFES (RAP FE Samples) or if you have your own BTP ABAP instance you can install it using the repository below:
- First of all, you need to have the abapGit plugin installed in your ADT
- Create a package called
- Link repository https://github.com/jcailan/rap-fe-samples
- Pull the source codes and then Activate the ABAP objects
- Publish the service bindings
- Lastly, generate data by executing class
Service Binding Preview
If you use the
Preview function of the Service Binding
ZUI_PRODUCTS_RS_O4, you will notice that the column chart is not available, this is because the annotations needed for this to work are not supported by ABAP CDS.
Fiori Element App with Local Annotations
But if I add the missing annotations using local annotations within the Fiori Element app itself, the problem is fixed.
If you are curious to know how I fixed it, I’ve added the generated Fiori Element app in the same repository, with local annotations that fixed the chart problem.
Using the RAP model, I was able to recreate the same functionalities of my CAP+FE app except only for the Chart Facet. Therefore, as an OData Service framework, CAP and RAP are both capable in terms of the functionalities used so far, however, CAP has shown superiority when it comes to the supported Fiori Elements annotations — but I consider this a minor setback since there’s nothing a local annotation could not fix.
Appreciate it if you have any comments, suggestions, or questions. Cheers!~
Hi Jhodel Cailan,
When I try to pull the objects(using the git plugin in ADT), the below error message stops proceeding further.
System failure: "Screen output without connection to the user." (For detailed information, check the generated short dump in transaction ST22 of the system. Can you please help here?
