Invoice Promotion problem

This is a strange one, perhaps you all can help.

We have a customer to whom we give a 0.25% "spoilage allowance" off of
each invoice.  This is entered as a discount in PRO110, and seems to
work fine as far as the AR, ORD, and BIL are concerned, with one minor
exception.

The INVOICE prints with an incorrect discount.  It hits AR and the GL
properly, and REPRINTS properly, but the first print is not correct.  We
did not find this until they started over-paying the invoices.

If by chance one of you has seen this before, please let me know how
you dealt with it.  In the alternative, if any of you can tell me in
what program such a thing could happen, I would appreciate it.

Thanks!
