The Separate Authorization of Invoices for Payment activity is used to authorize invoices for payment by a separate step. This is done after the invoices have been entered.
When the Supplier Invoice Authorization only by separate function option, in Enterprise/Company/ Invoice is enabled, authorization can only be made through a separate step in the Authorize Invoices for Payment page by clicking Authorize or by selecting the Authorized option of the invoice that you want to authorize.
For an invoice where the payment has been divided into several partial payment occasions, each installment must be authorized individually. In this case, the Installment Plan Exists option in the Authorize Invoices for Payment page will be enabled and each installment is displayed on a separate line.
See above.
After an invoice has been authorized, it can be paid.
