Access superclass member function

Question

How can I access a super class method from a child class method?

Here is an example that illustrates the problem: Let's say we have two classes

class parent definition.
public section.
  methods f.
endclass.

class child definition inheriting from parent.
public section.
  methods f redefinition.
  methods g.
endclass.

Now, in the implementation g, we want to call the implementation of the superclass fsimilar to the following syntactically incorrect fragment

class child implementation.
  method g.
    super->f( ). "forbidden: super-> can only be used to call the previous implementation of the same method
  endmethod.
endclass.

As indicated in the comment, super->it is impossible to use . You can help?

After some googling, it was suggested to copy the implementation parent->finto child->g, is this really the only way to do this?
