  The SAP error message SCRR_IOC163 indicates that the lock mode for a specific table has changed due to an XCLA (exclusive lock) condition. This typically occurs in the context of database operations where a lock is required to ensure data integrity during concurrent access.
  
  Cause:
  
  Lock Mode Change: The error message indicates that the lock mode for a table has changed from one state (e.g., shared lock) to another (e.g., exclusive lock). This can happen when a transaction attempts to acquire a lock that is incompatible with the current lock mode.
