R12: New Functionality Invoice Approval Parallel Processing (Doc ID 1904137.1)

Invoice approval workflow now supports parallelization at the invoice header level on 12.1.x and 12.2.x.

The main advantage for this change is to shorten the processing time for an invoice to get approved.

The parallel approval process imposes a hierarchical (tree) structure on the transaction’s approver list and enables each part of the tree at a given level to progress through its notification-approval cycle asynchronously.

This enables the approval process of each item in the transaction to continue irrespective of the progress of approval process of other items in the transaction and reduces the transaction's approval process time.

If user selects the parallel ordering mode, the approval notifications will be sent to all approvers at the same time. The invoice may get approved when one or all approvers approve the invoice, depending on the voting regime that is set up.
