ASCP Old Dock Date does not equal PO Promise Date

Hello,

We are running EBS 12.2.8. We have a purchase order that's approved with a promise date of 30-AUG-2024. In ASCP, I see the promised arrival date matches the promise date on the PO. However, the Old Dock Date shows 02-OCT-2024.

Profile MSC: Purchase Order Dock Date Calculation Preference = Promised Date

The problem only seems to be occurring with about 2 POs, and we have thousands of active POs, so it seems to be an isolated incident.

Any thoughts/ideas before I submit an SR?
