INVOICE APPROVAL > Invoices > Hold/release invoices for a PO
This is used to flag a Purchase Order as "on-hold" so that no one can process new invoices for the PO.
Also, if any invoices have already been processed for the PO but have not yet been transferred to Accounts Payable via the A/P Interface, these invoices will be excluded (not transferred) when the A/P interface is run.
This might be used if you are having a dispute with a supplier related to a PO.
