It sounds like you would have to setup SSO2 trust between AS ABAP and AS JAVA, so that an SSO2 logon ticket issued on AS ABAP system is trusted by the AS JAVA system. To do this you have to export the certificate used to digitally sign the SSO2 ticket and import into an ACL on the JAVA stack (in EvalauteTicketLoginModule options).
Also, maybe you can help me with something ? I was under the impression that BPC was a Windows .net application, but you mentioned it as an application running on AS ABAP. Am I confusing it with another application with a different name ?
Thanks,
