Smart SAP Assistant

• What is the cause and solution for SAP error message CMMFDOF_ORDER_FILL178 - Create of transact. terminated after retry; could not be locked (fill &1) ?

  The SAP error message CMMFDOF_ORDER_FILL178 indicates that a transaction was terminated after multiple retry attempts because it could not acquire a lock on a specific object (in this case, the fill object identified by &1). This typically occurs in scenarios where multiple processes or users are trying to access or modify the same data simultaneously, leading to a locking conflict.
  Causes:
  
  Concurrent Access: Multiple users or processes are trying to access or modify the same object at the same time, leading to a lock contention.
  Long-running Transactions: A transaction that takes too long to complete may hold a lock for an extended period, preventing other transactions from acquiring the necessary locks.
  Deadlocks: Situations where two or more transactions are waiting for each other to release locks, causing a deadlock.
  System Performance Issues: High system load or performance issues can exacerbate locking problems.
  
  Solutions:
  
  Retry the Transaction: Sometimes, simply retrying the transaction after a short wait can resolve the issue if the lock is released by the other process.
  Identify Locking Processes: Use transaction codes like SM12 (to view and manage locks) to identify which user or process is holding the lock. You can then decide whether to wait or terminate the blocking process.
  Optimize Long-running Transactions: Review and optimize any long-running transactions to ensure they complete more quickly and release locks sooner.
  Increase Lock Timeout: If applicable, consider increasing the lock timeout settings in your SAP system configuration, but this should be done with caution as it may lead to other issues.
  Review Application Logic: If the locking issue is frequent, review the application logic to minimize the chances of concurrent access to the same data.
  System Performance Tuning: Ensure that the SAP system is properly tuned for performance to reduce the likelihood of locking issues.
