• What is the cause and solution for SAP error message COM_DML_ENGINE004 - Object was changed ?

  The SAP error message COM_DML_ENGINE004: Object was changed typically occurs in the context of data manipulation in SAP systems, particularly when working with the Data Management Layer (DML) in SAP applications. This error indicates that the object you are trying to modify has been changed by another user or process since it was last read. This is a common issue in environments where multiple users or processes are accessing and modifying the same data concurrently.
  Cause:
  
  Concurrent Modifications: Another user or process has modified the object after you retrieved it but before you attempted to save your changes.
  Stale Data: The data you are working with is outdated, and the system has detected that the underlying data has changed.
  Locking Mechanisms: The object may be locked by another transaction, preventing your changes from being applied.
  
  Solution:
  
  Refresh the Data: Retrieve the latest version of the object from the database before making any changes. This ensures that you are working with the most current data.
  Handle Conflicts: Implement logic in your application to handle conflicts. For example, you can prompt the user to review the changes made by others and decide whether to overwrite or merge changes.
  Retry Mechanism: If your application allows, implement a retry mechanism that attempts to save the changes again after refreshing the data.
  Check Locks: Ensure that the object is not locked by another transaction. If it is, you may need to wait until the lock is released or handle the situation accordingly.
  User Notification: Inform users when their changes cannot be saved due to concurrent modifications, and provide options to resolve the conflict.
