Zero dollar payments

I apologize if this has been asked before.  We want to pay zero dollar invoices / payments, but when we do, there are some vendors who have outstanding credit balances which are adjusting the credit to reflect the amount of the debit and paying $0.  So for example, we have a vendor with debit of $100 and credit of $200 and the preliminary register is showing a paymnet for $0.00 and adjusting the credit to $100.

How can we correct this so that vendors with a credit balance will not adjust the credit amount and pay out?

Thanks!!!
