Ship Set Scenario in GOP Manage Order Promising Demands

Summary: We want to test Ship Set Scenario in Manage Order Promising Demands

We create two Lines, One Item has availability and other does not, we add same shipset in MOPD while creating these demand lines

When we select both lines and click on check availability, it gives different dates for both lines as SSDs

Technically for Shipset, it should pick the latest of the two Schedule dates for both lines and schedule the lines on same

We tested and Ship, Arrival set both, All Attributes were kept same except item and still got different dates for both lines

can someone advice on how we can test Ship Set Scenario in MOPD
