• What is the cause and solution for SAP error message /PM0/ABD_DPINTEGRAT002 - Category conflict between interface and implementing class ?

  The SAP error message /PM0/ABD_DPINTEGRAT002 indicates a "Category conflict between interface and implementing class." This error typically arises in the context of ABAP programming when there is a mismatch between the expected interface and the implementing class in terms of the method signatures or the categories defined.
  Cause:
  
  Mismatch in Method Signatures: The methods defined in the interface do not match the methods implemented in the class. This could be due to differences in parameters, return types, or method visibility.
  Incorrect Interface Implementation: The class may not be implementing all the methods defined in the interface, or it may be implementing methods that are not part of the interface.
  Category Conflicts: The interface and the implementing class may have different categories defined for the methods, such as public, protected, or private, leading to a conflict.
  
  Solution:
  
  Check Method Signatures: Review the methods defined in the interface and ensure that the implementing class has the same method signatures (name, parameters, return type).
  Implement Missing Methods: If the class does not implement all the methods defined in the interface, add the missing methods to the class.
  Adjust Visibility: Ensure that the visibility (public, protected, private) of the methods in the implementing class matches those defined in the interface.
  Recompile the Class: After making the necessary changes, recompile the class to ensure that the changes take effect.
  Check for Inheritance: If the class is inheriting from another class, ensure that the inherited methods do not conflict with the interface methods.
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for detailed information on interfaces and class implementations.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
  Debugging Tools: Use the ABAP debugger to step through the code and identify where the conflict arises.
  
  By following these steps, you should be able to resolve the error message and ensure that your interface and implementing class are correctly aligned.
