CPCL252 - Details

• The SAP error message CPCL252, which states "Sub-operation cannot be locked (lock management error)," typically occurs in the context of production planning and control, particularly when dealing with operations and sub-operations in a production order or a process order.

  Long-running Transactions: If a transaction takes too long to complete, it may hold locks longer than expected, causing other transactions to fail when they attempt to access the same data.
  System Performance Issues: High system load or performance issues can lead to delays in releasing locks, causing subsequent requests to fail.
  
  Configuration Issues: Incorrect configuration in the lock management
