• What is the cause and solution for SAP error message 28149 - Table &1 is currently being edited by user &2 ?

  The SAP error message 28149 indicates that a specific table (denoted as &1) is currently being edited by another user (denoted as &2). This typically occurs when multiple users attempt to access or modify the same table simultaneously, leading to a lock situation to maintain data integrity.
  Cause:
  
  Concurrent Access: Another user is currently editing the table, which prevents other users from making changes until the lock is released.
  Long-running Transactions: A transaction that takes a long time to complete may hold the lock for an extended period.
  Uncommitted Changes: If a user has made changes to the table but has not yet committed or rolled back the transaction, the lock remains in place.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish their transaction. Once the lock is released, you can try your operation again.
  Identify the Lock: Use transaction codes like SM12 (to view locks) to identify the user holding the lock and the specific transaction. This can help you understand the situation better.
  Contact the User: If possible, communicate with the user who is editing the table to see if they can complete their transaction sooner.
  Terminate the Session: If the lock is held by a user who is no longer active or if the transaction is stuck, a system administrator can terminate the session using transaction SM12. However, this should be done with caution, as it may lead to data loss or corruption.
  Review Lock Management: If this issue occurs frequently, it may be worth reviewing the application design or user processes to minimize concurrent access to critical tables.
  
  Related Information:
  
  Transaction Codes:
  
  SM12: To view and manage locks.
  SM21: To check system logs for any related issues.
  ST22: To check for dumps that might indicate underlying problems.
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific table or transaction you are working with.
  Documentation: Review SAP documentation on lock management and concurrency control for best practices.
  
  Always ensure that you have the necessary permissions and that you follow your organization's policies when dealing with locks and user sessions in SAP.
