Getting data from SAP backend into Gateway Hub

[nitesh_jain3]

Dear all,

I am new to Netweaver Gateway. In my landscape the IWBEP component has been installed in the Gateway Hub system. In my custom OData service i want to get the data from my backend SAP ERP system using a BAPI.

I have created my custom OData service with the relevant components and have implemented the service using the BAPI method. While implementing the service i referred to the BAPI method from the SAP ERP backend system using the RFC destination (ABAP connection i.e. connection type 3)  to the SAP ERP system created in my Gateway hub.

Now when i test the service, the service document and metadata XML are generated correctly. However when i test the entity set, i find that the data is NOT being extracted from the SAP ERP backend system.

What configuration/settings need to be maintained in the custom OData service so that the service refers to the correct SAP backend system? How does the gateway service determine from which system it should extract the data?

regards

Dear Goudham,

Creating the service in the Gateway system is not an issue. Have you installed the component IW_BEP in your backend SAP ECC server? What is the gateway deployment scenario you have implemented?

Dear all,

Further correspondence with an expert has revealed that to consume a BOR method successfully at run time from an SAP backend system (ERP in my case) it is mandatory to install the component IW_BEP in the backend system. Please note this is run time requirement and not a design time requirement.

Personally i am not satisfied with this framework requirement but cannot do much about it. A workaround is possible but that has its own overheads.
