what is pre-method for, versus "begin source enhancement" in method?
I use new enhancement framework (sap 7.0). Today I discovered the existence of pre-methods, but I don't understand in what situation we should use them, as "usual" source enhancements at the top of a method are equivalent, and so they are sufficient.
The only important difference I saw is that the pre-methods can only use public attributes and methods, whileas source enhancements can work also on private and protected members.
So, do you know what they are for?
thx a lot!
