V8 - Changes to Jobs/Packing Slips after Invoiced

Vantage ties your hands (rightfully so) on modifications to a lot of
information on jobs and packing slips after they've been shipped and

However, because of some oddities in our manufacturing environment, it
is fairly common for us to find, after the fact, that our Orders are
entered with incorrect quantities. Subsequently, the jobs we created
directly from the orders (using Order Job Wizard), and the packing
slip lines that we created from the order line/release have the wrong
quantity, and this is not found until after we invoice.

Does anyone have a procedure or method you use to fix these type of
shipping errors? Do you "return" the product somehow (using RMAs?),
then reship the product?

Thanks in advance.
