  WS394 &1 &2 cannot be displayed
  
  Cause
  This error typically occurs when SAP tries to display a screen (dynpro) or a GUI element identified by the parameters &1 and &2 but fails because:
  
  The screen number or program name specified does not exist.
  The screen is not included in the program or has been deleted.
  There is a mismatch or inconsistency in the screen number or program name.
  The screen is not active or has not been generated properly.
  The system is trying to call a screen that is not part of the current GUI status or transaction.
  
  
  Explanation of Parameters
  
  &1 usually represents the program name or module pool name.
  &2 usually represents the screen number.
  
  
  Common Scenarios
  
  Calling a screen that was removed or renamed.
  Incorrect screen number passed in a CALL SCREEN statement.
  Transport issues where the screen object was not transported properly.
  Custom developments where screen numbers are hardcoded and changed later.
  Issues in standard SAP programs due to missing or corrupted screens.
  
  
  Solution / Troubleshooting Steps
  
  
  Check the Screen and Program:
  
  Go to transaction SE80 or SE41.
  Enter the program/module pool name (&1) and check if the screen number (&2) exists.
  If the screen does not exist, investigate why the program is calling a non-existent screen.
  
  
  
  Check the Code:
  
  Look for CALL SCREEN &2 or similar statements in the program &1.
  Verify that the screen number is correct and corresponds to an existing screen.
  
  
  
  Activate the Screen:
  
  If the screen exists but is inactive, activate it in the Screen Painter (SE51).
  
  
  
  Transport and System Consistency:
  
  Check if the screen was transported correctly between systems.
  Reimport or re-transport the screen if missing.
  
  
  
  Debugging:
  
  Use the debugger to trace where the screen call is made.
  Check the values of the program and screen number at runtime.
  
  
  
  Check for Custom Code:
  
  If this is a custom program, verify that the screen numbers are not hardcoded incorrectly.
  Adjust the code or screen numbers accordingly.
