  The SAP error message EC109, which states "Menus cannot be assigned to a function key," typically occurs when there is an attempt to assign a menu to a function key in a way that is not allowed by the system. This can happen for various reasons, including configuration issues or incorrect settings in the SAP GUI.
  Causes:
  
  Incorrect Menu Assignment: The menu you are trying to assign to a function key may not be compatible or is not set up correctly in the system.
  Function Key Configuration: The function key may already be assigned to another action or may not be configured to accept menu assignments.

  Solutions:
  
  
  Check Menu Assignment:
  
  Ensure that the menu you are trying to assign is valid and correctly configured in the SAP system.
  Verify that the menu is not already assigned to another function key.
  
  
  
  Review Function Key Configuration:
