You should be able to void an EFT vendor payment the same way you can void a cheque. Sometimes when we submit the file to the bank, it says all payments are ok, but when the vendor's bank picks up the payment, the account number may be incorrect and the payment gets returned to our bank. Not being able to void the EFT causes a lot of manual correcting, including a journal to remove it from the bank, a new invoice and payment to the vendor which skews our actual transactions with the vendor when tracking how much business we have done with a vendor.
