Why is that?

Because that is the way it works, you can't call a subroutine until it is defined, the BEGIN block runs before the subroutine is defined. See BeginCheckInitEndUnitcheck.pl

And is that anyway I can make that sub below the BEGIN block ?

Why do you think you need a begin block? Because you don't you know :)
