Error RFC Portal 7.4 Connect with ERP

Dear All

I'm trying create a RFC for connect a portal nw 7.4 with ERP. after I create destination list (RFC name, Target host, Sys Number, Sys ID, and Logon Data) and try to Ping Destination, I got success message "Successfully connected to system xxx as user xxxxxx".

But when I try to configure in "Identity Management -> ABAP System -> Validate Configuration" I got error message "Validation failed. Technical detail: "Guest user ids are not unique, found multiple objects for Guest -- UACC.PRIVATE_DATASOURCE.un:Guest - UACC.R3_DATASOURCE4057428.GUEST"

I already try to create new RFC but still got same error message,

Could you tell me if there is a specific configuration ?

Thanks for all

Best Regard

Allan Sastrawan

    I bet you are using some ABAP stack as users source and there is user called "Guest" defined already in that system. Additionally "Guest" is a built in user in portal's UME, therefore portal is not able to uniquely identify user object having the same "Guest" id in both ABAP user source and UME.
