• What is the cause and solution for SAP error message /SCTM/RG117 - Program &1: object &2 is used as the instance of another class ?

  The SAP error message /SCTM/RG117 Program &1: object &2 is used as the instance of another class typically indicates that there is an issue with object-oriented programming in ABAP, specifically related to the use of class instances. This error occurs when an object is being used in a context where it is expected to be an instance of a different class than the one it actually is.
  Cause:
  
  Incorrect Object Type: The object being referenced is not of the expected class type. This can happen if the object was instantiated from a different class or if there is a mismatch in the expected class hierarchy.
  Inheritance Issues: If the class structure involves inheritance, the object might not be compatible with the expected superclass or interface.
  Type Casting Errors: If there is an attempt to cast an object to a different class type that it does not inherit from, this error can occur.
  
  Solution:
  
  Check Object Instantiation: Verify that the object in question is instantiated correctly from the expected class. Ensure that the constructor of the class is being called properly.
  Review Class Definitions: Look at the class definitions and ensure that the object is being used in a context that matches its class type. If the object is expected to be of a certain class, ensure that it is indeed an instance of that class or a subclass.
  Debugging: Use the ABAP debugger to inspect the object at runtime. Check the type of the object and ensure it matches the expected type.
  Type Casting: If type casting is being used, ensure that the object can be safely cast to the desired type. Use the CAST operator carefully and check for compatibility.
  Code Review: Review the code where the error occurs to ensure that the logic is sound and that the correct objects are being passed around.
