ARIS-SAP Sync-Error: INVALID_GLOBAL_ATTRIBUTE Message 031

Tried to synchronize ARIS 9.8.6 -> SAP SolMan 7.1 but got this error message:

Thu Apr 13 14:55:43 CEST 2017 - Die Fehlermeldung lautet: 'com.sap.conn.jco.AbapException: (126) INVALID_GLOBAL_ATTRIBUTE: INVALID_GLOBAL_ATTRIBUTE Message 031 of class SMSY_PPMS_API type E, Par[1]: BOBJ DEV SUITE ANALYTICS'

1. The Message appears a few minutes after starting the sync in the logfiles. Sync stops then....
2. Has anybody an idea / experience with that error message?

We currently have no idea, especially because we successfully sync-ed with ARIS 9.8.5 -> SAP SolMan7.1.

Thanks, Robert
