In this blog, you will learn how to create a simple RAP model. In this example, we will create a table, CDS view entity, Metadata extension, Behavior definition, Service definition, Service Binding.

We will create below application for creation of Driver detail with the help of FIORI element.


Step 1 --> Create table - ZRV_RAP_DRIVER

Right click on the package --> New --> Other ABAP Repository Object --> Select Database Table and enter the the name of the table.


Here is the code snippet.


Step 2 --> Create Root CDS Entity ZI_RAP_DRIVER

Right click on the package --> New --> Other ABAP Repository Object --> Select Data Definition and enter the the name of Root CDS Entity --> Select Define Root View Entity.


Here is the code snippet.


Step 3 --> Create a Metadata Extension

Right click on root view entity --> Select New Metadata Extension --> Enter the the name of Metadata Extension.


Here we annotate the CDS Entity and fields we add screen position, set selection field etc.

Here is the code snippet.


Step 4 --> Create a Behavior Definition

Right click on root view entity --> Select New Behavior Definition.

All detail will be already filled, just click next.


Here is the code snippet,

Note --> For managed scenario we don’t need a class. Create, Delete, Update functionality will work as a standard(It is required to handle for non-standard action, features, determination, validations and so on that will be covered in coming Part-2)


Step 5 --> Create a Service Definition

Right click on root view entity --> Select New Service Definition


Here is the code snippet.


Step 6 --> Create Service Binding

Right click on service definition --> Select New Service Binding.

Here we need to choose Binding type OData V2-UI or OData V4-UI, for now we have chosen V2-UI.



Now publish the Service by clicking on Publish button.


Our RAP model is completed, now test the application.

Test Application -->

Select Service and click on preview button.


Click on Go --> To see the data, if already available in system.


Click on CREATE --> Here we can create new driver.


UPDATE / DELETE --> To update or delete the record.

Select the entry from the list.


These buttons appear on the top right corner.


Conclusion --> After reading this blog you will be able to create simple RAP model application.
