When dealing with Electronic Data Interchange (EDI) solutions such as Transaction Manager or your Business System you will often deal with a common set of EDI Transactions that revolve around your business process. However - you can generalize most EDI processes into three types, Sales Order Process (SOP), Purchase Order Process (POP), and Warehouse Process (WHS).

The Purchase Order Process (POP) is typically associated with your Business System's Accounts Payable module that typically offers Purchase Orders, and Bills/Receipts associated with Vendors.

A typical Purchase Order Process (POP) solution will offer two primary EDI Transactions at a base level. An Outbound Purchase Order (850) and an Inbound Invoice (810).

An Outbound Purchase Order (850) that is generated by importing a Purchase Order that you create against a Vendor within your Business System will act as a request to be sent to your Trading Partner requesting to purchase items from them and to be shipped back to you.

A typical Outbound Purchase Order (850) would contain a list of the items you wish to purchase, as well as an address or store code to ship them to along with a requested price and quantity for each item.
​

An Inbound Invoice (810) is typically referred to as a Bill or Receipt which is a notice of the amount that you owe to your Trading Partner in response to the Purchase Order you've sent.

Depending on the Trading Partner, you may receive a Purchase Order Acknowledgement (855) which includes modifications to the requested Item/Quantities of the Purchase Order you've originally sent indicating the full amount either in price or quantity has changed.

For a Purchase Order Process (POP) Trading Partner most Business Systems sort all the Purchase Orders and their Bills under the Accounts Receivable or Purchases module.

You will often find all Trading Partners that you request goods to purchase from listed under a Vendors list.
