• What is the cause and solution for SAP error message S_AUT027 - Table &1 locked by user &2 (Start in display mode) ?

  The SAP error message S_AUT027 indicates that a specific table (denoted as &1) is currently locked by a user (denoted as &2), and as a result, you are only able to access it in display mode. This typically occurs when a user is editing or modifying data in the table, preventing other users from making changes until the lock is released.
  Cause:
  
  User Lock: A user is currently editing the table, which places a lock on it to prevent concurrent modifications that could lead to data inconsistencies.
  Long Transactions: If a user has a long-running transaction or has not properly saved and exited the transaction, the lock may persist longer than necessary.
  System Configuration: Certain configurations in the SAP system may lead to more frequent locking scenarios, especially in high-transaction environments.
  
  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.
  Identify the User: You can identify the user who has locked the table by using transaction codes like SM12 (for lock entries) or SM21 (for system logs). This will help you see which user is holding the lock.
  Contact the User: If possible, contact the user who has the lock and ask them to complete their transaction or log off if they are no longer working on it.
  Release the Lock: If the user is unavailable and the lock is causing significant issues, a system administrator can manually release the lock using transaction SM12. However, this should be done with caution, as it may lead to data inconsistencies if the user is in the middle of a transaction.
  Review Transaction Design: If this issue occurs frequently, it may be worth reviewing the design of the transactions that access the table to minimize locking scenarios.
