Unable to generate Single Shipment for Multiple Orders

Hi All,

We are unable to generate generate the single shipments for multiple Sales Order Lines.

We have integration in place where the Ship confirmation is completed in WMS and later we are assigning shipment numbers in Oracle Inventory.

However while running the Generate Shipment request program getting warning message as "These entities cannot be grouped because their grouping attributes do not match."

Also tried it manually and observed that multiple Shipment number is generated bases on number of Orders. So checked the Sales Order lines where Ship from, Ship to Location and Schedule Ship date are same on the order lines.
