• What is the cause and solution for SAP error message COM_DML_ENGINE182 - User & buffered changes ?

  The SAP error message COM_DML_ENGINE182 typically indicates that there are buffered changes made by a user that have not yet been committed or processed. This error can occur in various contexts, particularly when dealing with data manipulation in SAP systems, such as during the execution of a transaction or when trying to save changes to a database.
  Cause:
  
  Buffered Changes: The user has made changes to data that are still in a buffered state and have not been committed to the database.
  Session Management: The user may have multiple sessions open, and changes made in one session are not visible in another until they are committed.
  Transaction Issues: There may be issues with the transaction logic that prevent the changes from being processed correctly.
  Locking Issues: Another user or process may have locked the data, preventing the current user from committing their changes.
  
  Solution:
  
  Commit Changes: Ensure that all changes made by the user are committed. This can typically be done by executing a commit command or saving the transaction.
  Check for Locks: Investigate if there are any locks on the data that might be preventing the commit. You can use transaction codes like SM12 to check for locks.
  Review Session State: If multiple sessions are open, ensure that the user is aware of the changes made in each session and that they are properly managed.
  Error Handling: Implement error handling in the code to manage situations where buffered changes exist, ensuring that the user is prompted to commit or discard changes as necessary.
  Consult Documentation: Review SAP documentation or notes related to the specific transaction or module being used to see if there are any known issues or additional steps required.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (to check for locks), SM21 (to view system logs), and ST22 (to check for dumps).
  SAP Notes: Check SAP Notes for any updates or patches related to the error message. SAP frequently releases notes that address specific issues.
  User Training: Ensure that users are trained on how to properly manage their sessions and understand the implications of buffered changes.
  System Performance: Sometimes, performance issues can lead to delays in committing changes. Monitor system performance to ensure it is operating optimally.
  
  If the issue persists after trying the above solutions, it may be necessary to consult with your SAP Basis team or SAP support for further assistance.
