Java UME to ABAP backend

Can java UME support multiple ECC ABAP backends?

I looked at the UME configuration for a java instance and it seems as though there is a one to one relationship.

Is this a truly 1:1 relationship in UME - ABAP configuration.

Thanks

    I want to know if a UME can point to multiple ABAP backend. For instance I want my BI ABAP system and my ERP system to support a UME feed from my portal. Since it is java I cannot find anywhere that allows my java UME to point to to separate ABAP instance like BW and ERP.

    I don't see where a UME pointing to an ABAP backend can support more than one ABAP instance; java instance can only hook into the ABAP backend 1 time; thus a 1 for 1 infrastructure.

    Thank

      > You can have only one to one mapping between ABAP stack and UME.

      Actually, the ABAP logical system does not know that it is being used as a UME, other than the SAPJSF user being called from multiple Java logical systems (which is the same as the SID because it is not "client capable").

      So... a Chuck Norris full-round-house-kick happens: If you assign a user an ABAP UME role, then they are equiped with the corresponding Java UME groups on all Java SIDs pointing to it, and if one of them disrupt the connection then all of them go down...

      As the Java stacks are very "chatty" by nature, you will have a tough time trying to get the UME working again.

      I would class it as an ugly enough workaround, to be able to conclude that your statement is correct 😉

    Thank you for the information

    Can you further expand on "trust chains" and "hardwired connections" ?

    I want my java UME to support 2 or 3 backend ECC systems?

    Thanks

      What I meant is that you can use this in your portal applications, and the backend systems can trust each other and pass requests further, or if it is generic then you can enter a technical user into the destination definition of the connection.

      But UME itself offers to my knowledge only 1 ABAP logical system as "store" to logon with.

      On the ABAP side and in your applications you can become more creative - with all consequences.

      Cheers,

    Hi ,

    If you dont have single sign on configured then CUA can be one of the option for all the backend systems.

      That is strange advice...

      CUA master is an ABAP logical system and Java SID is not client capable, it is the logical system itself. So it is 1 Java : 1 ABAP from the view of Java and n : 1 from the view of ABAP (with ALL consequences associated to it!)

      If you add Logon Tickets to the scenario then you have 1 : 1 <--> 1 --> n (where n is anything) but I don't think that is Weyland's question, so my answer is irrelevant here.

      Perhaps you are refering to the "circus solution" of creating an ABAP client for each Java system and provisioning them from the CUA?

      That is however not a solution, but rather more like a Chuck Norris fighting against a fleet of battleships (except with a more realistic ending... 😊

      Enjoy the weekend,

      Julius
