• Message text: Class &1 is abstract

What causes this issue?

The class &V1& is abstract. Abstract classes cannot be used as
implementing classes in BAdI implementations. However, you can use
classes that inherit from abstract classes.

• What is the cause and solution for SAP error message SEEF_BADI089 - Class &1 is abstract ?

  The SAP error message SEEF_BADI089, which states "Class &1 is abstract," typically occurs when you are trying to instantiate an abstract class in ABAP. An abstract class in ABAP is a class that cannot be instantiated directly; it is meant to be a base class for other classes that implement its methods.
  Cause:
  
  Abstract Class Instantiation: The error arises when your code attempts to create an instance of an abstract class. Abstract classes are defined with the keyword ABSTRACT and are intended to provide a common interface or base functionality for derived classes.
  Missing Implementation: If you have defined a BAdI (Business Add-In) and have not implemented the necessary methods in a concrete class that extends the abstract class, this error can occur.
  
  Solution:
  
  Check Class Definition: Review the class definition of the class mentioned in the error message. Ensure that you are not trying to instantiate it directly.
  Implement Concrete Class: If you need to use the functionality of the abstract class, create a concrete class that inherits from it and implements the required methods. You can then instantiate this concrete class instead.
  Use BAdI Implementation: If this error is related to a BAdI, ensure that you have created an implementation for the BAdI and that it is active. You can do this by:
  
  Going to transaction SE18 to check the BAdI definition.
  Going to transaction SE19 to create or check the BAdI implementation.
  
  
  Check for Correct Usage: Ensure that your code is correctly using the BAdI implementation rather than trying to instantiate the abstract class directly.
  
  Related Information:
  
  ABAP Documentation: Review the ABAP documentation on abstract classes and BAdIs for more details on how to properly implement and use them.
  Debugging: Use the ABAP debugger to trace where the instantiation of the abstract class is happening in your code. This can help you identify the exact line causing the issue.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to the BAdI or class you are working with.
  
  By following these steps, you should be able to resolve the SEEF_BADI089 error and ensure that your code is correctly utilizing the class structure in ABAP.
