• What is the cause and solution for SAP error message OL721 - The object type already supports the method '&1' from another interface ?

  The SAP error message OL721 indicates that there is a conflict in the implementation of methods in an ABAP class or interface. Specifically, it means that the object type (class) you are trying to implement already has a method with the same name as the one you are trying to implement from another interface. This typically occurs when a class implements multiple interfaces that define methods with the same name.
  
  Cause:
  
  Multiple Interface Implementations: The class is implementing two or more interfaces that have a method with the same name.
  Inheritance Conflicts: If the class inherits from a superclass that already implements the method, and you are trying to implement it again from an interface.
  Method Signature Mismatch: If the method signatures (parameters, return types) do not match exactly, it can lead to confusion in implementation.
  
  
  Solution:
  
  Check Interface Definitions: Review the interfaces that the class is implementing. Identify the methods that have the same name
