How to create custom OData service in S/4HANA Cloud?

[SAPSupport]

Hello Support,
We have a Query regarding a Custom Data Source.
We got a requirement for a Custom Business Scenario in which we have developed Custom CDS for Form Template but it has been observed that it is not possible to make Custom Data Source through CDS.

We tried doing this in Data Source Extensions, but it allows only the addition of fields in existing data sources.

Is there any workaround for making a Completely New Custom Data Source?

Hello,

Yes, you can create your own Odata service or a rest endpoint using the RAP framework in the 3SL system.

You should have a user in your development system with tenant 080, assign the tenant a developer role, and then connect the tenant with your ADT.

There, you can develop the full-fledged implementation of your choice based on the RAP framework, the only recommended cloud framework.

Please let me know if you need more info.
