• What is the cause and solution for SAP error message WA453 - Receiver FM & can only be used for instance linkages ?

  The SAP error message:
  WA453 Receiver FM & can only be used for instance linkages
  typically occurs in the context of Function Module (FM) call linkage or instance method calls within ABAP Object-Oriented programming or when dealing with function module references.
  
  Cause
  This error message indicates that the receiver function module (FM) specified in a call or linkage can only be used for instance linkages. In other words, the FM you are trying to use as a receiver is designed to be called only in the context of an instance method call or instance linkage, not as a static or standalone FM call.
  Common scenarios causing this error:
  
  Attempting to call an FM that is defined as an instance method (or linked to an instance) in a static context.
  Using a function module reference or callback incorrectly, where the FM expects an instance linkage but is being called without an instance.
  Misuse of the CALL FUNCTION statement or method call syntax, mixing instance and static calls.
  
  
  Explanation
  
  Instance linkage means the FM is associated with a particular object instance (like a method of a class instance).
  The FM cannot be called independently without specifying the instance.
  The error enforces the correct usage of instance-bound FMs.
  
  
  Solution
  
  
  Check the FM definition:
  
  Verify if the FM is designed as an instance method or requires an instance linkage.
  If it is an instance method, you must call it via the instance of the class, not as a standalone FM.
  
  
  
  Adjust the call accordingly:
  
  If you are calling the FM directly, change the call to use the instance method call syntax.
  For example, instead of CALL FUNCTION 'FM_NAME', use the method call on the instance: instance->method_name( ).
  
  
  
  Review the linkage or callback setup:
  
  If you are passing the FM as a callback or reference, ensure it is passed with the instance context.
  For instance, use method references or object references properly.
  
  
  
  Check the program logic:
  
  Make sure that the FM is not being used in a static context if it requires an instance.
  If you need a static FM, use or create one that is not instance-bound.
  
  
  
  
  Related Information
  
  This error is related to the object-oriented programming model in ABAP, especially when mixing procedural FM calls and OO method calls.
  SAP Note or documentation on Function Module References and Instance Method Calls may provide additional insights.
  The error message class is usually WA4 (Function Module Call errors).
  Debugging the call stack and checking the FM attributes in SE37 or SE80 can help identify the nature of the FM.
