• What is the cause and solution for SAP error message OO292 - Parameter &1 &2 &3: Only BYVALUE allowed ( returning parameter ) ?

  The SAP error message OO292 indicates that there is an issue with the way parameters are defined in a method or function module, specifically regarding the use of returning parameters. The message states that only "BY VALUE" parameters are allowed for returning parameters.
  Cause:
  In ABAP (Advanced Business Application Programming), when you define a method or function module, you can specify how parameters are passed. There are different ways to pass parameters:
  
  BY VALUE: A copy of the actual parameter is passed to the method. Changes made to the parameter inside the method do not affect the original variable.
  BY REFERENCE: A reference to the actual parameter is passed. Changes made to the parameter inside the method affect the original variable.
  
  The error OO292 occurs when you try to define a returning parameter using a method that is not specified as "BY VALUE". In ABAP, returning parameters must be defined as "BY VALUE" because they are intended to return a value back to the caller without modifying the original variable.
  Solution:
  To resolve this error, you need to ensure that the returning parameter in your method or function module is defined correctly. Here are the steps to fix the issue:
  
  
  Check Method Definition: Go to the method definition in your class or function module.
  
  
  Modify Parameter Type: Ensure that the returning parameter is defined as "BY VALUE". You can do this by checking the parameter declaration in the method signature.
  
  
  Example: If your method looks like this:
  METHOD my_method
    RETURNING VALUE(rv_result) TYPE string.
  Ensure that rv_result is defined correctly as a returning parameter.
  
  
  Recompile: After making the necessary changes, recompile your code to ensure that the changes take effect.
