• What is the cause and solution for SAP error message AUT027 - Table &1 locked by user &2. Start in display mode ?

  The SAP error message AUT027 indicates that a specific table (denoted by &1) is currently locked by a user (denoted by &2), and as a result, you are only able to access it in display mode. This typically occurs when a user is performing an operation that requires exclusive access to the table, such as editing or updating data.
  Cause:
  
  User Lock: Another user is currently editing or has locked the table for some reason, preventing other users from making changes.
  Long-Running Transactions: A transaction that takes a long time to complete may hold a lock on the table for an extended period.
  Uncommitted Changes: If a user has made changes to the table but has not yet committed those changes, the lock will remain in place.
  System Configuration: Certain configurations or settings in the SAP system may lead to more frequent locking of tables.
  
  Solution:
  
  Wait for Release: The simplest solution is to wait until the user who has locked the table completes their transaction and releases the lock.
  Contact the User: If you know who the user is, you can contact them to see if they can complete their work or release the lock.
  Check Lock Entries: Use transaction code SM12 to check for lock entries. You can see which user has locked the table and the details of the lock.
  Delete Lock Entry: If necessary and if you have the appropriate authorizations, you can delete the lock entry from SM12. However, this should be done with caution, as it may lead to data inconsistencies if the user is still working on the data.
  Review Transaction Logic: If this is a recurring issue, review the logic of the transactions that are locking the table to see if they can be optimized to reduce lock duration.
  System Configuration: Consult with your SAP Basis team to review the system configuration and locking mechanisms to ensure they are set up optimally.
