Equivalent for SEGW in Embedded Steampunk

[Juwin]

Hello,

Is there a way to publish a OData-UI service based on Class-method, similar to the functionalities of SEGW in OnPrem systems? The only way explained in most documentation is RAP based programming, that uses CDS as a data source. But, not all functions that are possible in ABAP are possible in CDS.

Thanks

Hello juwin.thomas2.

How are you? I have excluded the Tag "SAP S/4HANA Cloud" and included the Tag "SAP S/4HANA Cloud ABAP Environment" for this question, as Embedded Steampunk is related to ABAP Environment.

Regards.

Juliano Romanato.

Hello Juwin,

Thanks RAP should be used to model services in Embedded Steampunk. SEGW based services allow us to use statements like Commit work etc which is not allowed in Embedded steampunk, hence not supported.

Also, almost all functions which are possible in ABAP are also possible in CDS. CDS doesn't only mean CDS views, it also has CDS custom entities in case you have complex select operations which are not possible in CDS views. Also in RAP you have option to create unmanaged BOs where you can write all your custom logic in classes.

Thanks,

Aman Garg

"almost all functions"... thats the problem. Not everything is possible. And hence, my question.

Can you share a scenario which you find difficult to fit in with RAP?
