• What is the cause and solution for SAP error message BM028 - Changed data was saved ?

  The SAP error message BM028 ("Changed data was saved") typically indicates that a user has attempted to save changes to a document or record in the system, but the system has detected that the data has been modified by another user or process since it was last read. This is a common issue in environments where multiple users are working on the same data simultaneously.
  Cause:
  
  Concurrent Modifications: Another user or process has changed the data after you retrieved it but before you attempted to save your changes.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If the data is locked by another user, you may receive this message.
  Session Timeout: If your session has been inactive for a while, the data may have been updated by another user when you try to save.
  
  Solution:
  
  Refresh the Data: Before saving, refresh the data to ensure you have the latest version. You can do this by reloading the screen or navigating away and back to the document.
  Review Changes: After refreshing, review the changes made by others. You may need to reconcile your changes with the new data.
  Reapply Your Changes: If necessary, reapply your changes to the updated data and attempt to save again.
  Communicate with Team Members: If you are working in a collaborative environment, communicate with your team to avoid overlapping changes.
  Check for Locks: If you suspect a lock, check the transaction codes (like SM12) to see if the data is locked by another user and resolve it accordingly.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to check locks), SM21 (to view system logs), and ST22 (to check dumps) for troubleshooting.
  User Training: Ensure that users are trained on how to handle concurrent data changes and the importance of refreshing data before making edits.
