  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WER_CUST003: The program-screen combination &1-&2 already exists.
  
  Cause:
  This error occurs when you try to create or modify a screen (Dynpro) in a program with a screen number that already exists in the system for that program. In SAP, each screen number within a program must be unique. If you attempt to create a new screen with a number that is already assigned to another screen in the same program, the system raises this error.
  
  Explanation:
  
  Program: The ABAP program or module pool name.
  Screen number: The screen (Dynpro) number you are trying to create or assign.
  The combination of program name and screen number must be unique.
  The error message indicates that the screen number you want to use is already assigned to another screen in the same program.
  
  
  Solution:
  
  
  Check existing screens:  
  
  Go to transaction SE80 (Object Navigator).
  Open the program/module pool.
  Expand the "Screens" node.
  Verify if the screen number you want to create already exists.
  
  
  
  Use a different screen number:  
  
  Choose a screen number that is not already used in the program.
  Screen numbers typically range from 0100 to 9999, but some ranges may be reserved depending on the application.
  
  
  
  If you want to modify an existing screen:  
  
  Instead of creating a new screen, open the existing screen and make your changes.
  
  
  
  Check for transport or system inconsistencies:  
  
  Sometimes, inconsistencies or incomplete transports can cause the system to think a screen exists when it should not.
  Use transaction SE51 (Screen Painter) to check the screen.
  If necessary, consult your Basis team to check for inconsistencies.
  
  
  
  
  Related Information:
  
  Transaction SE80: Object Navigator to manage programs and screens.
