Sales Orders Stuck in "Approval Pending" / Lines "Not Started" Without Matching Any Approval rule

Since Wednesday, May 6, 2026, approximately 70% of Sales Orders created in Oracle Fusion Order Management enter the header status "Approval Pending" with lines remaining in "Not Started", even though the order conditions do not meet any of the configured Approval Rules that would trigger an approval hold.
The remaining 30% of orders process normally through orchestration without any intervention, which indicates the issue is not universal but is triggered by a specific condition or combination of attributes not yet identified.
Important: No Oracle patches, updates, or maintenance windows were applied during the week of May 4–10, 2026. The issue appeared spontaneously with no change introduced on the Oracle Cloud side. No configuration changes were made by the TIC team prior to the issue onset.
