Unable to Schedule a Sales Order Line to a Calendar Exception Date using Override Schedule Option

We are unable to schedule a Sales Order Line to a Calendar Exception Date by only overriding the Scheduled Ship Date of an Order Line.

We are trying to update a Sales Order Line to a Calendar Exception Date (10-Jan-2026) by updating only Schedule Ship Date of an Order Line. Schedule Arrival Date is updated to the previous working day at the scheduling step (09-Jan-2026) Since Schedule Ship Date cannot be greater than Scheduled Arrival Date, Schedule Ship Date got auto updated to (09-Jan-2026), though we are trying to schedule it to (10-Jan-2026)
The schedule Ship Date is unchanged only when both Schedule Ship Date and Scheduled Arrival Date are updated for an Order line.
