A split shipment is normally used with bulk material (SOT items, Standard withOut Tag). A shipment is often split because the supplier agrees to split the delivery after the agreement is placed. For example, partial shipments due to a large amount require a split of an item shipment.
The supplier creates the number of splits he needs, copies the value of the original line, and adjusts the IS Sub field to 2, 3, 4, and so on.
The supplier sends the updated Excel sheet back to you. This updated Excel sheet can be imported into Smart Materials to add or update item shipment data.
