When someone submits an invoice and leaves the invoice number blank, Expense Management automatically chooses an invoice number IR-###
We don't want to use that arbitrary number and we can't make invoice number a required field, so we would like the option to turn off the IR-### numbering system
We would also like this auto numbering feature turned off. It creates duplicate payments. When I searched for an invoice number and couldn't find it, I re-entered the invoice resulting in $2700 over payment.
This also causes confusion for our vendors when they get checks with erroneous invoice numbers on it.
Here is a screenshot.
