• What is the cause and solution for SAP error message AC087 - Control data currently blocked by & ?

  The SAP error message AC087, which states "Control data currently blocked by &," typically occurs in the context of Asset Accounting (FI-AA) when a user attempts to make changes to asset master data or perform certain transactions while the asset is locked by another user or process. This locking mechanism is in place to prevent data inconsistencies and ensure data integrity.
  Cause:
  
  Concurrent Access: Another user or process is currently accessing or modifying the asset data, which leads to a lock on the control data.
  Transaction in Progress: A transaction that involves the asset is still in progress, preventing other users from making changes.
  System Lock: The system may have a temporary lock due to a previous transaction that did not complete properly.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for a few moments and then retrying the operation may resolve the issue.
  Identify the Locking User: Use transaction code SM12 to check for locks on the asset. This transaction allows you to see which user is currently holding the lock. If necessary, you can contact that user to coordinate the changes.
  Release the Lock: If you have the necessary authorizations, you can manually release the lock in transaction SM12. However, this should be done with caution to avoid data inconsistencies.
  Check for Background Jobs: Sometimes, background jobs may be running that are locking the asset data. You can check for any relevant background jobs using transaction SM37.
  Consult with IT Support: If the issue persists and you cannot identify the cause, it may be necessary to consult with your IT support team or SAP Basis team for further investigation.
