LB256 - Details

• The SAP error message LB256, which states "Transaction MB05 is not permitted for dialog," typically occurs when a user attempts to execute the MB05 transaction in a dialog session, but the system is configured to restrict this transaction to background processing only.
  
  Cause:
  
  Transaction Restrictions: The transaction MB05 (which is used for posting goods movements) is set up in the system to be executed only in the background. This is often done for performance reasons or to ensure that certain processes are handled in a controlled manner.
  User Role/Authorization: The user may not have the necessary authorizations to execute the transaction in the dialog mode, although this is less common for this specific error.
  
  
  Solution:
  
  Run in Background: If you need to execute the MB05 transaction, you should run it in the background. You can do this by using the transaction code SM37 to monitor background jobs or by using the Submit command in ABAP
