order split and xdock

Here my scenario.

An order can go direct or through a xdock.

if the order is small, it is consolidated fine in xdock location. However, if the order is to big to any equipment, system does split it but create two direct shipments. I would expect to have one direct shipment and the reaming be consolidated in xdock.

Ex.

Order A with 51 units.

Order B with 1 unit. Both orders with same destination.

Larger equipment can take 50 units.

Solution expected:

Order A split: 50 units going direct.

Order A: 1 unit going through xdoc and consolidated with order B.

Solution got:

Order A: 50 units going direct.
