Fixing Inventory/Invoicing error

[Ray <mai...@so...>]

I managed to enter the wrong part # on a customer invoice and didn't notice
until after I had posted it.  I then went back to that invoice number and
changed the part to the correct one and posted it again however my inventory
didn't get adjusted acordingly.  What do I do now and how do I avoid this in
the future?
