Are Enterprise Services required under DUET FP1, GW 2.0?

[Former Member]

In an earlier project we did prior to DUET FP1, GW 2.0, we did not use Enterprise Services. For the new project, I have a valid GW Data and Consumption Model generated under GW 2.0. When I try to follow the old instructions for the non-Enterprise Services install and generate the flat service under transaction SIMGH, the new screens have required fields for Enterprise Services Repository (ESR), so obviously it wants Enterprise Services information. The old instructions (screens) did not have ESR fields. Is there a way around this or is Enterprise Services required for DUET FP1, GW 2.0? Are there instructions on how to create a non-Enterprise Services instance?

BTW, I was following the "Build Duet Enterprise Applications with Gateway RFC or BOR Generator" document for creating my project. I ran into a similar problem here where there was no Enterprise Services set up for the "Create BDC Model from GSDO Type" step.

Thanks,

Hi Andy,

Your thread title is a little misleading.

Enterprise Services are not required; you typically generate or handcraft own Gateway Services, connected to either RFC's of Web Services (plain BAPI or Enterprise Services; both possible).

But your question actually boils down to whether or not Enterprise Service Repository is required for designing Duet Enterprise Services. The answer to that is Yes: the ESR is also in FP1 still needed during design time, that is if you are using the Gateway Design Time tools (*). At runtime it is not required.

(*) In case of handcrafting approach, you could theoretically do without; that implies that you will somehow have to define the Service Interface, corresponding to the required SAP syntax and semantics. In practice this is NOT advisable, it is very error prone to try handcraft the Service Interface .wsdl...

Best regards, William.
