Under system options there is a Processing Option "Credits on Invoices". Help states: "Credits are normally entered on credit notes. But if you want to be able to enter credits on invoices as well, turn this option on."

How and where do I do this in order entry? I get quite a few work orders where a customer picks up items and returns other items (most often when they make a mistake measuring). It would save a ton of time and paper if this can be done on one form.

Thanks.

The option allows the quantity shipped to be negative, hence the credit.
