Hello everyone, in this blog we will discuss on how to create OData service for ABAP CDS views in SEGW based on Referenced Data Source.
In previous blog How to create OData service for ABAP CDS Views we have seen an easy approach on exposing the ABAP CDS view as an OData service using the annotation @OData.publish: true and also the restrictions/disadvantages by following the approach.
Referenced Data Source
To overcome the above restriction, we can follow this approach. Below are the features supported.
Advantages and Features Supported
- Multiple Entities i.e multiple CDS views
- Actions using Function Imports in SEGW
- CDS View with parameters
- CDS annotations considered and derived at runtime
- CDS changes will be reflected at runtime, no need for re-activation

On the Create Object Directory Entry dialog box, enter a value (e.g. $TMP) to the Package field, and then choose Save.
Now the service classes are generated.
