When approving a cost card for payment, you may encounter the following error. This action would result in the approval of one or more payment vouchers with negative total disbursed amount
Projector does not support negative payment vouchers. A negative payment voucher indicates that someone owes you money, whereas a payment voucher, by its very name, indicates that you owe someone else money.
Solution 1
If the sum of your selected expense items is not negative, then some of your positive expenses must already be on an unapproved payment voucher. Visit the Payment Voucher Browser and find the current expense report. Look for items that are on an unapproved voucher. Once you find them, you can add the negative items in from here and then approve them together. Or you can delete the voucher and try again from the expense browser.
Solution 2
Do not approve the negative cost card for payment until there are additional expenses to make the balance positive.
Solution 3
Remove the original cost card by uninvoicing, unapproving, and deleting it from expense entry.
Solution 4
Find the original Payment Voucher associated with the vendor invoice, roll it back/mark as unpaid, adjust the amount to reflect the recent credit and reapprove the Payment Voucher.
