  Error Message
  WA683 & &: Parameter & does not exist
  
  Message Class: WA6
  Message Number: 83
  Message Text: Parameter & does not exist
  
  
  Cause
  This error occurs when a program or function module tries to access a parameter that is not defined or does not exist in the current context. The placeholder & is replaced by the actual parameter name that the system could not find.
  Common scenarios include:
  
  A missing or incorrectly named parameter in a function module call.
  A parameter that was expected in a selection screen or report but was not declared.
  A typo or mismatch in parameter names between the caller and the called program/module.
  Attempting to access a parameter that was removed or never created in a custom development or enhancement.
  
  
  Solution
  
  
  Check Parameter Names:
  
  Verify the spelling and existence of the parameter in the program, function module, or method.
  Ensure that the parameter is declared properly in the interface or selection screen.
  
  
  
  Review the Calling Code:
  
  If the error occurs during a function module call, check the parameter list passed to the function.
  Make sure all required parameters are included and correctly named.
  
  
  
  Debugging:
  
  Use the ABAP debugger to identify where the error occurs.
  Check the internal tables or structures that hold parameters.
  Look for dynamic parameter access (e.g., using ASSIGN COMPONENT or GET PARAMETER) that might fail if the parameter name is incorrect.
  
  
  
  Check Custom Code or Enhancements:
  
  If this error appears after a custom development or enhancement, review the changes for missing or incorrectly referenced parameters.
