Does anyone know of a reliable way to determine what SalesOrder drove creation of PurchaseOrder.
SO created PO Suggestion.
PO Suggestion was converted to PO
How can I determine this after the fact?
Unrelated, but the ultimate goal is I have to work all the way back through this process:
SO -> PO -> ICPO TO SO
I need to copy details from original SO in Company A to the resultant SO in Company B
I am guessing that due to the way the customer processes their orders, this is unavailable to me 
It seems like this requires Buy To Order, but (for some reason I dont know yet) the customer does NOT want to use Buy To Order.
The SO isn’t Buy to Order, so there’s no direct connection between the SO and PO, just the indirect demand connection from driving stock negative.
You can use Multi-Level Pegging to get a more granular look at which supplies satisfy which demands, but it still won’t give you a concrete link between a PO and SO. You can select it to run during MRP, or you can run it afterwards as its own process. If you need this information in a BAQ or report, the links are in Erp.PegLink, Erp.PegDmdMst, and Erp.PegSupMst tables.
Thanks for the suggestions. I definitely need a concrete link. I am querying the customer to determine what their issues with using Buy To Order is in this case. Maybe solving that issue will be an easier nut to crack.
