• What is the cause and solution for SAP error message DT959 - Changes to table & were not passed on to lock object & ?

  The SAP error message DT959 indicates that changes made to a database table were not successfully passed on to the associated lock object. This typically occurs in scenarios where there is a discrepancy between the data in the table and the lock object that is supposed to manage concurrent access to that data.
  Cause:
  
  Inconsistent Data: The data in the table may have been changed without the corresponding lock object being updated. This can happen if the application logic does not properly handle locking mechanisms.
  Lock Object Issues: The lock object itself may not be defined correctly, or there may be issues with the way it is being used in the program.
  Database Transactions: If a transaction is not committed properly, it can lead to inconsistencies between the table and the lock object.
  Development Errors: Custom developments or modifications in the ABAP code that do not adhere to SAP standards for handling locks can lead to this error.
  
  Solution:
  
  Check Lock Object Definition: Ensure that the lock object is defined correctly in the Data Dictionary (SE11). Verify that it corresponds to the table in question and that the fields used for locking are appropriate.
  Review ABAP Code: Examine the ABAP code that interacts with the table and the lock object. Ensure that the locking mechanism is being used correctly (e.g., using ENQUEUE and DEQUEUE statements).
  Transaction Management: Ensure that all database changes are properly committed. If using explicit transactions, make sure that the COMMIT WORK statement is executed after changes.
  Debugging: Use the debugger to trace the execution of the program and identify where the inconsistency occurs. Look for any missed lock or unlock calls.
  Check for Concurrent Access: Investigate if multiple processes are trying to access the same data simultaneously, which could lead to locking issues.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide patches or updates.
  
  Related Information:
  
  Lock Objects: Lock objects in SAP are used to prevent data inconsistencies by ensuring that only one user can modify a record at a time.
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE37 (Function Modules), and SE80 (Object Navigator) for debugging and analyzing the issue.
  SAP Documentation: Refer to SAP documentation for best practices on using lock objects and handling database transactions.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or ABAP development team for further assistance.
