Interesting structure question: We are a distribution company that sells a lot of items via dropship. Our business workflow is when a dropship sales order is created we create a purchase order to the vendor. The PO and the sales order are related via a sales order field on the PO. Once shipped the vendor sends the shipping information which we then use to create the item fulfillment for the workflow. We are looking to automate the item fulfillment record creation via a csv import of the ship tracking number and the PO number (which connects to the sales order). What would be the best way to go about this?
