• What is the cause and solution for SAP error message WER161 - Method contains reference parameter which is not assigned ?

  SAP Error Message:
  WER161 - Method contains reference parameter which is not assigned
  
  Cause
  This error occurs when a method in an ABAP class has a reference parameter (i.e., a parameter passed by reference) that is not assigned (i.e., it is INITIAL or NULL) at the time the method is called or within the method implementation where the parameter is expected to be assigned.
  In ABAP Object-Oriented programming, when a method has a parameter defined as a reference type (e.g., REF TO <type>), the caller must pass a valid reference object. If the reference parameter is not assigned (i.e., it points to nothing), and the method tries to access or use it, the runtime raises this error.
  
  Explanation
  
  Reference parameters are pointers to objects or data references.
  If a method expects a reference parameter, it assumes the parameter is assigned (points to a valid object).
  If the parameter is INITIAL (not assigned), the method cannot operate on it.
