• What is the cause and solution for SAP error message EC291 - The function key & is assigned to multiple pushbuttons ?

  The SAP error message EC291 indicates that a function key (often referred to as a shortcut key) is assigned to multiple pushbuttons within a particular screen or transaction. This can lead to ambiguity in the system, as the function key would not know which action to perform when pressed.
  Cause:
  
  Duplicate Assignments: The primary cause of this error is that the same function key has been assigned to more than one pushbutton in the same context (screen or transaction).
  Configuration Issues: This can occur due to incorrect configuration in the screen layout or during the development of custom transactions or screens.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), it might lead to conflicts if the same function key was assigned in both systems.
  
  Solution:
  
  Identify the Pushbuttons: Check the screen layout or the transaction where the error occurs. Identify all pushbuttons that are assigned the same function key.
  Reassign Function Keys: Change the assignment of one or more of the conflicting pushbuttons to different function keys. This can be done in the screen painter or through the relevant transaction code (e.g., SE80 for Object Navigator).
  Testing: After making changes, test the transaction to ensure that the function keys now work as intended without conflicts.
  Documentation: Document the changes made to avoid future conflicts and ensure that the function key assignments are unique.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE80 (Object Navigator) or SE41 (Menu Painter) to manage function keys and pushbutton assignments.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Screen Painter: If you are working with custom screens, you may need to use the Screen Painter (SE80) to modify the screen layout and resolve the conflict.
  Function Key Configuration: Familiarize yourself with how function keys are configured in SAP, as this will help in troubleshooting similar issues in the future.
  
  By following these steps, you should be able to resolve the EC291 error and ensure that your function keys are correctly assigned without conflicts.
