  The SAP error message CRM_MKTTGGRP_EXP155 typically indicates that there is an issue with locking a specific table in the SAP system. This error can occur in various scenarios, particularly when multiple users or processes are trying to access or modify the same data concurrently.
  Cause:
  
  Concurrent Access: The most common cause of this error is that another user or process is currently accessing the table, leading to a lock that prevents your transaction from proceeding.
