• What is the cause and solution for SAP error message EC224 - Function code &1 has been assigned more than once ?

  The SAP error message EC224, which states "Function code &1 has been assigned more than once," typically occurs in the context of SAP GUI or when dealing with screen elements in a custom transaction or program. This error indicates that a function code (a code that triggers a specific action in the SAP GUI) has been defined multiple times for the same screen or context, leading to ambiguity in the system.
  Cause:
  
  Duplicate Function Codes: The most common cause of this error is that the same function code has been assigned to multiple buttons or actions on the same screen.
  Custom Development: If you are working with custom screens or transactions, it is possible that during the development process, the same function code was inadvertently assigned to different elements.
  Screen Modifications: Changes made to standard SAP screens or custom screens without proper checks can lead to this issue.
  
  Solution:
  
  
  Identify Duplicate Assignments:
  
  Go to the screen in question (using transaction SE80 or SE41).
  Check the screen elements (buttons, menu items, etc.) to see where the function code is assigned.
  Ensure that each function code is unique for the screen.
  
  
  
  Modify Function Code Assignments:
  
  If you find that the same function code is assigned to multiple elements, you will need to change one of the assignments to a different function code.
  Ensure that the new function code does not conflict with other existing codes.
  
  
  
  Testing:
  
  After making changes, test the screen or transaction to ensure that the error no longer occurs and that all functionalities work as expected.
  
  
  
  Documentation:
  
  Document the changes made to avoid similar issues in the future and to maintain clarity for other developers.
  
  
  
  Related Information:

  Debugging: If the issue persists, consider using the debugger to trace the execution and see where the function codes are being called or assigned.
