• What is the cause and solution for SAP error message VR655 - Data is blocked by another user so it can only be displayed ( & ) ?

  SAP Error Message:
  
  VR655 - Data is blocked by another user so it can only be displayed (&)
  
  Cause:
  This error occurs when a user tries to edit or change a data record (such as a vendor master record, customer master record, or other master data) that is currently locked by another user. SAP uses a lock mechanism to prevent simultaneous changes to the same data by multiple users, ensuring data consistency and avoiding conflicts.
  When a record is locked by another user, the system allows you only to display the data but not to edit it. The message VR655 indicates that the data is currently locked and can only be viewed.
  
  Explanation:
  
  SAP uses enqueue locks to lock master data or transactional data during editing.
  When a user opens a record for editing, SAP places a lock on that record.
  If another user tries to edit the same record, SAP prevents it and shows this message.
  The lock remains until the first user saves or cancels the transaction or the session ends.
  
  
  Solution:
  
  
  Wait and Retry:
  
  The simplest solution is to wait until the other user finishes editing and releases the lock.
  
  
  Identify the User Holding the Lock:
  
  You can find out who holds the lock by using transaction SM12 (Lock Entries).  
  
  Go to SM12  
  Enter the object or user name if known, or leave blank to see all locks.  
  Find the lock related to the data you want to edit.  
  Identify the user holding the lock.
  
  
  
  Contact the User:
  
  Ask the user to finish their work and release the lock by saving or canceling the transaction.
  
  
  Force Unlock (with Caution):
  
  If the user is not available or the lock is stale (e.g., due to a session crash), an administrator can delete the lock entry in SM12.  
  
  Select the lock entry and choose Delete.  
  Be careful: Forcing unlock can cause data inconsistencies if the user was in the middle of a transaction.
  
  
  
  Check for Long-Running Sessions:
  
  Sometimes locks remain because users have open sessions or transactions that were not properly closed. You can check user sessions in SM04 or AL08 and ask users to log off if necessary.
  
  
  
  Related Information:
  
  Transaction SM12: Display and delete lock entries.  
  Transaction SM04 / AL08: Monitor user sessions.  
  Enqueue Server: SAP component responsible for managing locks.  
  Locks are released automatically when the user saves, cancels, or exits the transaction properly.

  Tools
  SM12 (locks), SM04/AL08 (sessions)
  
  
  Precautions
  Avoid force unlocking unless necessary to prevent data inconsistencies
  
  
  
  
  If you frequently encounter this issue, consider reviewing user training on proper transaction handling or implementing timeout settings for locks to reduce stale locks.
