Invoice Number Duplicates

@Kayla Euler you'll want to ensure you don't have a lot of other values included in your duplicate invoice settings. For example, if you include a date option or description field in the list for duplicate invoice criteria then it will allow you to have a duplicate invoice number under that vendor as long as the date is different and/or the description has even one different character in its value (i.e. Invoice for AP vs. Invoice for A.P.).

So the best recommendation is to only have the bare minimum you'd need like invoice number and amount in your duplicate invoice criteria to avoid a duplicate number under the same vendor. Note, that will not prevent you from using the same invoice number with different vendors, of course, just within one vendor's activity.

If you have additional fields listed there, you can right-click and remove the line. Hope this helps!

@Kayla Euler Hey Kayla, if your only criteria is the invoice number and it still allowed you to create (and save) a duplicate invoice number under the same vendor, definitely contact support with that screenshot of your business rules configuration there – that should not be happening!
