Yes, but then you never did define things the same way as the rest of

ALL of your "front ends" are restricted - by your lack of ability.

And some organizations do it the right way. But you wouldn't know what
that is.
And "designing and developing ... for several decades"? You've been

No, you haven't. You've developed a bunch of crap and called it an ERP

Yes, this is the best help he could get - on exactly what NOT to do.
