• What is the cause and solution for SAP error message SCRL636 - Method &1 already exists. ?

  The SAP error message SCRL636, which states "Method &1 already exists," typically occurs when you are trying to create a method in a class or interface that already has a method with the same name and signature. This can happen in ABAP programming when you are defining methods in a class or interface and inadvertently attempt to define a duplicate method.
  Cause:
  
  Duplicate Method Definition: You are trying to create a method with the same name and parameters as an existing method in the same class or interface.
  Inheritance: If the class is inheriting from a parent class that already has a method with the same name, this can also trigger the error.
  Interface Implementation: If you are implementing an interface that already has a method defined, and you try to redefine it without proper overriding, this error can occur.
  
  Solution:
  
  Check Existing Methods: Review the class or interface to see if the method you are trying to create already exists. You can do this by looking at the method list in the class/interface definition.
  Rename the Method: If the method already exists and you need a different functionality, consider renaming your method to avoid the conflict.
  Override the Method: If you are trying to change the behavior of an existing method from a parent class, ensure you are using the REDEFINITION keyword correctly to override the method.
  Check Inherited Methods: If your class is inheriting from a superclass, check the superclass for the method definition. If it exists, you may need to override it properly.
  Interface Compliance: If implementing an interface, ensure that your method signature matches exactly with the interface definition.
  
  Related Information:
  
  ABAP Class and Method Definitions: Familiarize yourself with the syntax and rules for defining classes and methods in ABAP.
