• What is the cause and solution for SAP error message /SCWM/IT_DEVKIT003 - Class &1 does not inherit from &2 ?

  The SAP error message /SCWM/IT_DEVKIT003 Class &1 does not inherit from &2 typically occurs in the context of SAP Extended Warehouse Management (EWM) when there is an issue with class inheritance in the system. This error indicates that a specific class (denoted as &1) is expected to inherit from another class (denoted as &2), but it does not.
  Cause:
  
  Incorrect Class Definition: The class that is being referenced does not properly inherit from the expected parent class. This could be due to a misconfiguration or an error in the class definition.
  Custom Development Issues: If there are custom classes or enhancements, they may not be correctly set up to inherit from the required base classes.
  Transport Issues: If the class was transported from another system, it may not have been transported correctly, leading to inconsistencies in class definitions.
  
  Solution:
  
  
  Check Class Definitions: 
  
  Go to the Class Builder (Transaction Code: SE24) and check the definition of the class &1. Ensure that it is set to inherit from the correct parent class &2.
  If the class is supposed to inherit from a different class, update the inheritance accordingly.
  
  
  
  Review Custom Code: 
  
  If the error is related to custom development, review the custom classes to ensure they are correctly defined and inheriting from the appropriate classes.
  Make sure that any custom classes are properly implemented and do not violate the inheritance structure.
  
  
  
  Transport Management: 
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included and transported correctly.
  If necessary, re-transport the classes or related objects to ensure consistency.
  
  
  
  Check for Updates: 
  
  Ensure that your SAP system is up to date with the latest support packages and notes, as there may be fixes or updates related to class inheritance issues.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to the specific classes involved to understand their intended use and inheritance structure.
  
  
  
  Debugging: 
  
  If the issue persists, consider debugging the relevant code to identify where the class is being instantiated or called, which may provide further insights into the problem.
