This can happen due to various reasons, including database locks, contention, or issues with the underlying database system.
  Causes:
  
  Database Locking Issues: The table TUL_CPU may be locked by another transaction or user, preventing the current operation from acquiring the necessary lock.

  Check for Locks: Use transaction codes like SM12 (for lock entries) to check if there are any existing locks on the TUL_CPU table. If you find locks that are no longer needed, you can release them.
  Analyze Long-Running Transactions: Use transaction codes like SM50 or SM66 to monitor active processes and identify any long-running transactions that may be holding locks.
  Database Administration: If you have access to the database, you can check for locks at the database level (e.g., using SQL queries) and resolve any issues.
  Increase Timeout Settings: If applicable, consider increasing the timeout settings for database connections to allow more time for transactions to complete.
  Review Application Logic: Ensure that the application logic is optimized to minimize locking contention, such as by reducing the scope of transactions or using appropriate isolation levels.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
