    • Hi Cindi,

      Good question. PO (Purchase Order) EDI documents are transmitted from the sender to the receiver. If your customer wants to make a change to the order, then the customer will send another EDI document, a POC (Purchase Order Change) which will show you the changes the customer wishes to make. The PO document is commonly referred to as an 850 EDI document type and the POC is referred to as an 860 type document. You can read more about EDI PO’s at this blog post
