• What is the cause and solution for SAP error message UAS001 - Method was called up for incorrect object type ?

  The SAP error message UAS001 ("Method was called up for incorrect object type") typically occurs when there is a mismatch between the expected object type and the actual object type being used in a method call within an ABAP program or a function module. This can happen in various scenarios, such as when working with classes, interfaces, or function modules.
  Causes:
  
  Incorrect Object Type: The method is being called on an object that does not match the expected type. For example, if a method is defined for a specific class and you try to call it on an instance of a different class.
  Inheritance Issues: If the method is defined in a superclass and you are trying to call it on a subclass instance that does not implement or override the method correctly.
  Interface Implementation: If the method is defined in an interface and the class does not implement the interface correctly, this error can occur.
  Typographical Errors: Sometimes, simple typographical errors in the code can lead to this issue, such as calling the wrong method or using the wrong object reference.
  
  Solutions:
  
  Check Object Type: Verify that the object on which the method is being called is of the correct type. You can use the TYPEOF statement in ABAP to check the type of the object at runtime.
  Review Method Definition: Ensure that the method is defined correctly in the class or interface and that it is being called on the correct object instance.
  Debugging: Use the ABAP debugger to step through the code and identify where the incorrect object type is being used. This can help pinpoint the exact line of code causing the issue.
  Check Inheritance: If you are working with inheritance, ensure that the method is properly implemented in the subclass if it is abstract or virtual in the superclass.
  Consult Documentation: Review the SAP documentation for the specific method or class you are working with to ensure you are using it correctly.
