You can block an invoice for payment by entering a "Y" in the ACP500 screen
when you are entering the vendor invoice. If it is already entered, you can
maintain the invoice and change the hold value from "N" to "Y", or vice versa
if
you are releasing it to be available for selection, using ACP510 - Invoice
maintenance or by revising the existing voucher with an action code "2" in
ACP500, if I recollect correctly.
You run the ACP250 report to list the invoices that are being held. Also you
can hold the vendor in the vendor master which will hold the payment of all
invoices related to that vendor.
Good luck.
