• What is the cause and solution for SAP error message CL136 - Object & is not of type & ?

  The SAP error message CL136, which states "Object & is not of type &," typically occurs in the context of class or object-oriented programming within the SAP ABAP environment. This error indicates that there is a type mismatch between the object being referenced and the expected type.
  Cause:
  
  Type Mismatch: The most common cause of this error is that the object you are trying to use is not of the expected class type. For example, you might be trying to call a method or access a property on an object that is not an instance of the class you expect.
  Incorrect Object Initialization: The object may not have been initialized correctly, or it may have been assigned a value of a different type.
  Inheritance Issues: If you are working with inheritance, the object might not be an instance of the subclass that you are trying to use.
  Dynamic Type Checking: If you are using dynamic programming techniques (like CREATE OBJECT or CALL METHOD), the type of the object may not match the expected type at runtime.
  
  Solution:
  
  
  Check Object Type: Verify the type of the object you are working with. You can use the DESCRIBE statement to check the type of the object at runtime.
  DATA: lv_type TYPE string.
  DESCRIBE FIELD <your_object> TYPE lv_type.
  Compare lv_type with the expected type.
  
  
  Initialization: Ensure that the object is properly initialized before you use it. If you are using CREATE OBJECT, make sure that the class name is correct and that the object is instantiated.
  
  
  Casting: If you are certain that the object should be of a certain type, you can use type casting. However, be cautious with this approach as it can lead to runtime errors if the object is not of the expected type.
  DATA: lo_object TYPE REF TO <expected_class>.
  lo_object ?= <your_object>.
  
  
  Check Inheritance: If you are dealing with inheritance, ensure that the object is indeed an instance of the expected subclass. You can use the IS INSTANCE OF statement to check the type.
  IF <your_object> IS INSTANCE OF <expected_class>.
      " Safe to use the object
  ELSE.
      " Handle the error
  ENDIF.
  
  
  Debugging: Use the debugger to step through the code and inspect the object at runtime. This can help you identify where the type mismatch is occurring.
  
  
  Related Information:
  
  Documentation: Refer to the SAP documentation for the specific classes and methods you are using to ensure you understand the expected types.
  SAP Notes: Check SAP Notes for any known issues related to the specific classes or methods you are using.
  Community Forums: Consider searching or posting on SAP community forums for additional insights or similar experiences from other developers.
  
  By following these steps, you should be able to identify the cause of the CL136 error and implement a solution to resolve it.
