• What is the cause and solution for SAP error message SWF_EXP_001179 - '&1' is an instance method. Call-up only possible using object instance ?

  The SAP error message SWF_EXP_001179 indicates that there is an attempt to call an instance method without having an object instance of the class that contains the method. In object-oriented programming, instance methods require an object of the class to be created before they can be invoked. This error typically occurs in the context of workflow or ABAP programming when the method is being called incorrectly.
  Cause:
  
  Incorrect Method Call: The method being called is an instance method, but it is being called statically (without an object instance).
  Missing Object Instance: The object instance that should be used to call the method has not been created or is not available in the current context.
  Typographical Error: There might be a typo in the method name or the class name, leading to confusion in the method resolution.
  
  Solution:
  
  
  Create an Object Instance: Ensure that you create an instance of the class before calling the instance method. For example:
  DATA: lo_object TYPE REF TO your_class.
  CREATE OBJECT lo_object.
  lo_object->your_instance_method( ).
  
  
  Check Method Declaration: Verify that the method you are trying to call is indeed an instance method and not a static method. If it is a static method, you should call it using the class name:
  your_class=>your_static_method( ).
  
  
  Review the Workflow Configuration: If this error occurs in a workflow context, check the workflow configuration to ensure that the correct object instance is being passed to the method.
  
  
  Debugging: Use the ABAP debugger to trace the execution and check if the object instance is being created and passed correctly.
  
  
  Consult Documentation: Review the class documentation to understand the expected usage of the method and ensure that you are following the correct syntax.
  
  
  Related Information:
  
  ABAP Object-Oriented Programming: Understanding the principles of object-oriented programming in ABAP can help prevent such errors. Familiarize yourself with concepts like classes, objects, instance methods, and static methods.
  SAP Notes and Community: Check SAP Notes or the SAP Community for any known issues or additional guidance related to this error message.
  Error Handling: Implement error handling in your code to gracefully manage situations where an object instance might not be available.
  
  By following these steps, you should be able to resolve the SWF_EXP_001179 error and ensure that your method calls are correctly structured.
