EC291 - Details

• 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
