Auto-Approve Non-Catalog Requisitions, but Require Reapproval on Subsequent Changes

Hello Experts,

We have a business requirement related to requisition approvals in Oracle Fusion Procurement.

Requirement:

1. All non-catalog requisitions should be automatically approved upon initial submission without requiring manual approval.
2. However, if the requisition is subsequently modified and resubmitted (for example, quantity, amount, description, accounting, or other attributes are changed), the business wants the requisition to go through a different approval process requiring manual approval.
3. The updated requisition should not be auto-approved again after the change.

We are exploring whether this can be achieved through BPM approval rules, reapproval configurations, or any other standard Oracle Fusion functionality.

Has anyone implemented a similar requirement?
