• What is the cause and solution for SAP error message C0335 - - Charact.& &: Parameter & already assigned ?

  The SAP error message C0335 - "Character & &: Parameter & already assigned" typically occurs when there is an attempt to assign a value to a parameter that has already been assigned a value in the context of a report or program. This can happen in various scenarios, such as when using selection screens, function modules, or when defining parameters in ABAP programs.
  Cause:
  
  Duplicate Assignment: The error is primarily caused by trying to assign a value to a parameter that has already been assigned a value earlier in the code.
  Incorrect Logic: There may be logical errors in the code where the same parameter is being assigned multiple times without being reset or cleared.
  Parameter Scope: The parameter might be defined in a way that it cannot be reassigned once it has been set.
  
  Solution:
  
  Check Code for Duplicate Assignments: Review the code to identify where the parameter is being assigned. Ensure that each parameter is assigned only once or is reset before being assigned again.
  Use Clear or Initial: If you need to reassign a parameter, consider using the CLEAR statement to reset the parameter before assigning a new value.
  CLEAR parameter_name.
  parameter_name = new_value.
  
  Review Parameter Definition: Ensure that the parameter is defined correctly in the program. If it is a selection screen parameter, check the screen logic to ensure it is not being assigned multiple times.
  Debugging: Use the debugger to step through the code and monitor the assignment of the parameter. This can help identify where the duplicate assignment is occurring.
  Consult Documentation: If the parameter is part of a standard SAP function or module, refer to the SAP documentation for any specific rules or constraints regarding its usage.
