You can also post multiple payable invoices from the list page. For more information, seePosting Payable Invoices.
Background Posting
In some situations, the posting is not immediate. The document is set to "Ready to Post" and it is batched up for posting by a scheduled job. A "Ready to Post" document cannot be amended, discarded, printed, or manually posted.
Payable invoices are batched up for posting by a scheduled job in the following situations:
When the payable invoice exceeds the lines threshold set for payable invoices in the Accounting Settings custom setting.
When the payable invoice has its tax value calculated by AvaTax.
When you post payable invoices from a list view.
Standard Posting
When a payable invoice is posted, two or more transaction line items are posted to your current company's general ledger and the payable invoice is assigned a transaction number. The sum of these transaction line items is zero in document, home and dual currency.
