• What is the cause and solution for SAP error message MJ045 - Copying is not allowed in display mode ?

  The SAP error message MJ045 ("Copying is not allowed in display mode") typically occurs when a user attempts to copy or modify data in a transaction or report that is currently in display mode. This error is common in various SAP modules, particularly in the context of Material Management (MM) or Production Planning (PP).
  Cause:
  The primary cause of this error is that the user is trying to perform an action (like copying a document or data) that is not permitted in display mode. In SAP, display mode is intended for viewing data only, and any modifications or copying actions require the user to be in change mode.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Switch to Change Mode: 
  
  If you need to copy or modify data, ensure that you are in change mode. Look for a button or option labeled "Change" or "Edit" in the SAP GUI. This will allow you to make changes or copy data as needed.
  
  
  
  Check User Permissions: 
  
  Ensure that your user role has the necessary permissions to perform the action you are trying to execute. If you do not have the required permissions, you may need to contact your SAP administrator to adjust your user role.
  
  
  
  Review Transaction Codes: 
  
  Make sure you are using the correct transaction code for the action you want to perform. Some transaction codes are specifically designed for display purposes, while others allow for changes.
  
  
  
  Consult Documentation: 
  
  If you are unsure about the process or the specific transaction you are using, refer to SAP documentation or user manuals for guidance on how to perform the desired action correctly.
