/IWBEP/SBUI017 - Details

• The SAP error message /IWBEP/SBUI017 Class '&1' cannot be used; implementation is set to abstract typically occurs in the context of SAP Gateway and OData services. This error indicates that the class specified (denoted by &1) is defined as an abstract class, meaning it cannot be instantiated directly. Instead, it is intended to be subclassed, and a concrete implementation must be provided.
  
  Cause:
  
  Abstract Class: The class you are trying to use is abstract and does not have a concrete implementation. Abstract classes are designed to be base classes that provide a template for other classes.
  Missing Implementation: There may be a missing or incorrectly configured implementation class that should extend the abstract class.
  
  Configuration Issues: The OData service or the related configuration might not be set up correctly, leading to the system trying to use an abstract class instead of a concrete one.
  
  
  Solution:
  
  Check Class Definition: Verify the class definition in the ABAP Workbench
