• What is the cause and solution for SAP error message 15036 - No locks exist ?

  The SAP error message "15036 No locks exist" typically indicates that a specific lock object or lock entry that the system is trying to access does not exist. This can occur in various scenarios, such as when a program attempts to release a lock that was never set or when there is an issue with the lock management in the system.
  Causes:
  
  Lock Not Set: The most common cause is that the program is trying to release a lock that was never established.
  Session Termination: If a session that held a lock was terminated unexpectedly, the lock may not be available anymore.
  Incorrect Lock Object: The program may be referencing an incorrect or non-existent lock object.
  Database Issues: There could be underlying database issues that prevent the lock from being recognized.
  
  Solutions:
  
  Check Lock Logic: Review the code to ensure that locks are being set before they are released. Ensure that the logic for setting and releasing locks is correctly implemented.
  Debugging: Use the debugger to trace the execution of the program and check the lock management logic. This can help identify where the lock is supposed to be set.
  Transaction Management: Ensure that the transaction handling is correct. If a transaction is rolled back, it may affect the locks.
  Review Lock Objects: Verify that the lock objects being used are correctly defined in the system and that they exist in the data dictionary.
  Check for Session Issues: If the error occurs after a session termination, check the system logs for any related errors or warnings that might indicate why the session was terminated.
