This activity is used to post all the postings in the posting proposal, to their respective cost or balance accounts. Usually when you are working with an invoice without a posting proposal, the invoice will be finally posted when it is balanced and the postings cannot be changed thereafter. However, when you are using a posting proposal you can modify, remove and add postings as necessary to the proposal until all the posting lines are authorized by the persons responsible. When all the users connected to the proposal as different roles have authorized, confirmed, or acknowledged the posting lines as applicable, it should be finally posted. The final posting of invoices can be done manually, or can be scheduled to be performed at a pre-scheduled date and time as a batch job. It will be possible to specify whether the voucher date or invoice date will be used as the voucher date for all invoices.
As a result of this activity, the invoice will be finally posted, and the posting proposal will not be possible to modify. If the Automatic Payment Authorization option is enabled, the invoice will be automatically authorized for payment at the time of the final posting if the payment authorization is not done earlier.
