• What is the cause and solution for SAP error message SWB_TODO_CHECKS104 - Variable &1 at CALL SCREEN is not defined in the program ?

  The SAP error message SWB_TODO_CHECKS104 indicates that there is a variable &1 that is being referenced in a CALL SCREEN statement, but it has not been defined in the program. This typically occurs in ABAP programs when a variable is expected to hold a value or reference but is not properly declared or initialized.
  Cause
  The error can be caused by several factors:
  
  Variable Not Declared: The variable being referenced in the CALL SCREEN statement has not been declared in the program.
  Scope Issues: The variable may be declared in a different scope (e.g., within a different subroutine or method) and is not accessible in the context where it is being used.
  Typographical Error: There may be a typo in the variable name, leading to the system not recognizing it.
  Dynamic Screen Handling: If the program is dynamically handling screens, the variable may not be properly passed or initialized before the screen call.
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check Variable Declaration:
  
  Ensure that the variable &1 is declared in the program. You can do this by searching for the variable name in the ABAP editor.
  
  
  
  Declare the Variable:
  
  If the variable is not declared, you need to declare it in the appropriate section of your program. For example:
  DATA: lv_variable TYPE your_data_type.
  
  
  
  
  Check Scope:
  
  If the variable is declared but not accessible, check the scope of the variable. Ensure that it is declared in a global or appropriate local scope that is accessible where the CALL SCREEN statement is used.
  
  
  
  Correct Typographical Errors:
  
  Verify that the variable name is spelled correctly in both the declaration and the CALL SCREEN statement.
  
  
  
  Initialize the Variable:
  
  Make sure that the variable is initialized with a value before it is used in the CALL SCREEN statement.
  
  
  
  Review Dynamic Screen Logic:
  
  If you are using dynamic screen handling, ensure that the variable is being passed correctly to the screen and that it is initialized before the screen is called.
