Smart SAP Assistant

• What is the cause and solution for SAP error message SADL_CM_ACCESS_PRTCT004 - Write access to &1 violates active write lock ?

  The SAP error message SADL_CM_ACCESS_PRTCT004 indicates that there is an attempt to write to a data object that is currently locked for writing by another transaction or user. This is a common issue in SAP systems where data integrity is maintained through locking mechanisms to prevent concurrent modifications that could lead to inconsistencies.
  Cause:
  The error occurs when:
  
  A user or process tries to modify a record that is already locked by another user or process.
  The lock could be due to an ongoing transaction that has not yet been completed or released.
  The lock might be a result of a long-running transaction or a deadlock situation.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Lock:
  
  Use transaction code SM12 to check for existing locks. You can filter by the user ID or the object being locked.
  Look for the specific lock entry that corresponds to the object you are trying to modify.
  
  
  
  Release the Lock:
  
  If you find that a lock is held by a user or process that is no longer active, you can manually delete the lock entry from SM12. However, be cautious with this approach, as it may lead to data inconsistencies if the original transaction is still in progress.
  
  
  
  Wait for the Lock to be Released:
  
  If the lock is held by an active transaction, you may need to wait until that transaction is completed and the lock is released automatically.
  
  
  
  Check for Long-Running Transactions:
  
  Investigate if there are any long-running transactions that might be causing the lock. If necessary, communicate with the user or team responsible for that transaction.
  
  
  
  Review Custom Code:
  
  If this error occurs frequently, review any custom code or enhancements that may be causing locks to be held longer than necessary.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that might address this specific error or provide additional guidance.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SM12: Display and manage lock entries.
  SM21: Check system logs for any related issues.
  ST22: Analyze dumps that might provide insights into the error.
  
  
  
  Lock Management: Understanding how SAP handles locks can help in troubleshooting. Locks can be exclusive (write locks) or shared (read locks), and they are managed at the database level.
  
  
  Performance Considerations: Frequent locking issues may indicate performance bottlenecks or inefficient transaction handling in your SAP environment.
  
  
  By following these steps, you should be able to diagnose and resolve the issue related to the SADL_CM_ACCESS_PRTCT004 error message.
