Merge shipments
One order can create several shipments because of backorders or partial allocations. When you process an order with more than one shipment, multiple invoices are created for each shipment. Because customers may use a single invoice, the Warehouse solution has a feature called merge shipments which creates one invoice for the same document, destination, and location.
Note: Only unreleased shipments can be
merged, so merge shipments on the feedback forms before you release the shipping feedback.
After you merge the shipments, you cannot undo the merge. The shipments must all be at the
same processing stage when you merge them.
