Changes to be done in DOA without any impact on pending invoices.

Currently, the organization is following Approval group-based DOA matrix for payables invoice approvals and there are regular changes in the DOA. Every time a change is done, there is a compulsion for the client to withdraw and resubmit the invoice for approvals. Currently the requirement is to make changes to the DOA without it impacting the pending invoices.

Note: Role based approvals cannot be configured as per the organization work structure. Let us know if there is any other way to configure rules without it impacting the pending invoices.
