• What is the cause and solution for SAP error message WER184 - The mode &1 is not valid: edit(&2) or display (&3) are allowed ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WER184 The mode &1 is not valid: edit(&2) or display (&3) are allowed
  
  Cause:
  This error occurs when a program or transaction tries to set a screen or a function module in a mode that is not supported. The message indicates that the mode passed to the screen or function is invalid. The system expects the mode to be either edit or display, but it received a different mode.
  
  &1 = The invalid mode passed.
  &2 = Allowed mode "edit".
  &3 = Allowed mode "display".
  
  For example, if the program tries to call a screen or function module with mode "create" or "delete" but only "edit" or "display" are allowed, this error will be raised.
  
  When does it occur?
  
  When calling a standard SAP function module or screen that only supports "edit" or "display" modes.
  When a custom program or enhancement incorrectly passes a mode parameter.
  When the mode parameter is dynamically set and ends up with an invalid value.
  
  
  Solution:
  
  
  Check the mode parameter being passed to the function module or screen.  
  
  Ensure that the mode is either 'E' (edit) or 'D' (display), or whatever the allowed values are for that particular function or screen.
  
  
  
  Debug the program to find where the mode is set or passed.  
  
  Look for the variable or parameter that holds the mode.
  Verify its value before the call.
  
  
  
  Correct the mode value in the code or configuration.  
  
  If the mode is hardcoded or comes from user input, validate it before passing.
  If the mode is passed from another program or screen, check the calling logic.
  
  
  
  Refer to SAP documentation or function module documentation to confirm allowed modes.
  
  
  
  Example:
  If a function module expects mode 'E' or 'D' but receives 'C' (create), the error will occur.
  CALL FUNCTION 'SOME_FUNCTION_MODULE'
    EXPORTING
      mode = 'C'.  " Invalid mode, should be 'E' or 'D'
  Change to:
  CALL FUNCTION 'SOME_FUNCTION_MODULE'
    EXPORTING
      mode = 'E'.  " Valid mode
  
  Related Information:
  
  This message is part of the WER message class, which relates to workflow or screen handling.
  Check SAP Notes or documentation for the specific function module or transaction you are using.
  Sometimes this error can occur in custom developments or enhancements where mode handling is not properly implemented.
  If you are unsure about allowed modes, check the function module interface or screen attributes in SE80 or SE41.
