EU379 - Details

• The SAP error message EU379, which states "Interface methods cannot be documented within classes," typically occurs when you attempt to document methods of an interface within a class implementation. In ABAP (Advanced Business Application Programming), interfaces and classes have different rules regarding documentation.
  
  Cause:
  The error arises because:
  
  In ABAP, methods defined in an interface cannot have documentation (comments) added directly within a class that implements the interface. Documentation for interface methods should be provided in the interface definition itself, not in the implementing class.
  
  
  Solution:
  To resolve this error, you should:
  
  Document in the Interface: Ensure that you provide the necessary documentation for the interface methods directly in the interface definition. This is where the documentation should reside.
  Remove Class-Level Documentation: If you have added documentation for the interface methods in the class implementation, remove that documentation. Instead, focus on documenting the class-specific methods or any additional functionality that the class provides beyond the interface.
