Need clarification on SEGW for odata service

Hi Experts,

I am traditionally creating Model provider class(MDP) & Data provider class(RDP) in se80, intergration them with model and generating the service.

But now for my new assignment i am starting on SEGW tcode where i am creating the entityset and entity as below

Now i have created the runtime airfacts which inturn creted the MDP & RDP. in traditional method we will creating the get_entity_set in /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_ENTITYSET. but here the methods productset_get_entityset is created where i am writing the business logic, i have kept the breakpoint but it is not triggered and in the execution screen the productset_get_entityset doesn't available, then i found that this is in protected method as shown below.

My question is: where do i need to write the business logic. Please help me. Awaiting for your reply.

Thanks,

Gowtham

    Hi gowtham,

    In zcl_XXXXXXXXXXXXXX_DPC_EXT Class you have to redefine the methods for your implementation.

    For Example for (Query) operation u have to redefine the

    method /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_ENTITYSET

    Hello Raja,

    First redefine the method /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_ENTITYSET in your DPC_EXT class and call the method productset_get_entityset where u have written your logic inside it and return the response. Only if u do this u will be able to stop in GW with debugger.

    What you have done is Without redefining /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_ENTITYSET method in DPC_EXT, you have just redefined method productset_get_entityset and written logic ? How can you stop with BP at runtime ? 😊 not possible right ? The call has to be delegated to productset_get_entityset method by redefining /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_ENTITYSET method and inside that you will be calling productset_get_entityset method 😊

    Do this. You should be able to Debug.

      Hello Raja,

      You can write the logic inside /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_ENTITYSET directly and return the response. It will work.


      But i would suggest the below way -

      You can write the logic inside the method productset_get_entityset and call this method inside /IWBEP/IF_MGW_APPL_SRV_RUNTIME~GET_ENTITYSET within a CASE statement .

      Delegate the calls to the corresponding methods by checking based on Entity_Set_Name using CASE statement.

      When Entity_set_name name is ProductSet then call productset_get_entityset method and return the response.

      With this you can resolve your issue and can stop flow with a Break Point.

      Regards,
