Shipment of goods to the buyer. Partial redemption. Return of goods to the warehouse?

Question

Delivery

Where to see and how to return unsold goods from those previously loaded to the buyer’s address, with a partial redemption of the order, and how to return to the warehouse back in accounting in 1C UT 11.4
When shipped earlier, there was no transfer of ownership, ownership passes at the moment the goods are transferred to the buyer upon delivery .
We are stuck in the chain of operations at the stage of the delivery report.)
I would like to see a report on unpurchased goods in the context of "deliverers".
Maybe someone came across a solution using the standard functionality of 1C UT.

Answer 1

What scheme works?
If it's just that the idea arises of a scheme for working with commission agents.
As a result, if there is no "commissioner's report", then the goods hang behind it.
