EC148 - Details

• The SAP error message EC148, which states "Do not assign the function key & to the first pushbutton," typically occurs in the context of SAP GUI programming, particularly when dealing with screen elements in a dialog program or module pool.
  
  Cause:
  This error arises when a function key (like F1, F2, etc.) is incorrectly assigned to the first pushbutton on a screen. In SAP GUI, the first pushbutton is expected to be associated with the default action, which is usually linked to the Enter key. Assigning a function key to this button can lead to confusion in user interactions, as the system expects the first button to handle the primary action.
  
  Solution:
  To resolve this error, you should:
  
  
  Check the Screen Layout: Open the screen in the Screen Painter (SE80 or SE41) and review the properties of the pushbuttons.
  
  
  Modify Pushbutton Properties: Ensure that the first pushbutton does not have a function key assigned to it.
