ShipHead OTS - OTS00000/00000 - where's the data for this?

Been a minute since I re-vistied the one time ship to logic from a ShipHead point of view- I get where the order OTS is held, etc.- but when I open a customer shipment that is pointed to “OTS00000/00000” where is it getting the actual address info that it’s displaying? Has anyone decompiled this logic? Does this go back to the sales order to find this, is it stored in an intermediate table somewhere?

I’m going to keep digging here, but hoping someone else can point me to the place in the database where this is being held, a place I can work back to from the ShipHead.PackNum

Using OTSOrderNum holds the related OTS data, however, what happens when it’s a release level OTS, and they all differ… very interesting, maybe that’s the /00000 in the OTS0000/000000

Really wish they would have just used fields, but the first set of 0’s is the line, the next set, after the “/” is the release- from the limited testing I’ve done.
