Multiple Backends

Hi all, has anyone experienced any problems using R/3 4.6 and R/3 5.7 as the multiple backends? I know it is possible, but just thinking about BAPIs function modules etc... are there any specific problem using two SAP backends of different versions?

I would appreciate any information you can provide. I have read the backend integration information and see no specific problems with it but if anyone has done it I would appreciate a heads up of potential problems.

    Hi Tracey

    I have recently finished a project where we connected to more than 10 different SAP backend system 4.6C and up.

    Most off the issues we had were more to do with Customising and Master data differences.

    We used Extended Classic Scenario.

    Areas to check are:

    Units of Measure - we ended up switching over to using ISO UoM when communicating with the backend systems.

    Currencies - just check them.

    Payment Terms - especially when using contracts in EBP.

    Vendors & Plants - just make sure the correct backend references are coming through. Also for vendors you need to make sure that only vendors that exist in the backend system that the follow-on documents will be created in are visable to the user.

    Users - hopefully users don't do any cross backend system activities, e.g. switch to shop.

    Products - If the same material code can appear in both backend systems, life can start to get interesting. We had items from catalogue with product IDs in, however we didn't pass back the logical system from catalogue. The result was that we always got an express error message if a material code existed in more than one backend system. The end result was that we were forced to modify the system!

    From a communications point of view just make sure you set the backend versions correctly then the BAPIs will look after the rest.

    Be careful if you end-up having to write your own RFC calls or BAPIs, you should make sure you build in handling for different backend versions.

    Otherwise have fun.
