IDeliverySourceId Property

Identifier of delivery that existed before splitting it by multiple cash registers. Depending on settings, a single order can be split by multiple cash registers before payment, producing multiple orders. At the same time base delivery is also split; at this moment SourceId of all produced deliveries is set to Id of base delivery. If delivery was not split by cash registers, SourceId returns null.
