Summary :
This SAP Note addresses issues encountered post-system export, copy, or upgrade, specifically with RFCs resulting in errors such as "CALL_FUNCTION_SIGNET_INCOMPL." Such issues stem from the invalidation of SECSTORE entries "/HMAC_INDEP/RFC_EXTERNAL_TICKET_4_TRUSTED_SYSTEM" and "/HMAC_INDEP/RFC_INTERNAL_TICKET_4_TRUSTED_SYSTEM" following SID changes. The resolution involves applying specific kernel patches, deleting the problematic SECSTORE entries, or using the cleanup report RS_TT_CLEANUP_SECSTORE. These actions should restore RFC functionality and system stability.
