Is it possible to backdate the ship confirmation in Oracle to a date prior to the pick release date?

We have tried backdating the "Actual Ship Date" field at the shipment header manually, but during ship confirmation, Oracle displays an error message stating that the shipment date cannot be prior to the pick release date.

The issue arises because, in our 3PL system, order lines are ship confirmed first, and the shipment details are passed to the user the next day to manually complete the ship confirmation in Oracle ERP.

This causes a problem at month-end. Where ship-confirmed order line details in the 3PL system are received by the user on the first of the next month, making it impossible to ship confirm the order lines for the previous month.
