What is an EDI order?

Learn what an EDI ORDERS message is and why it plays a crucial role in automated order processing and modern supply chains.

What is an EDI ORDERS message?

An EDI ORDERS message is the electronic purchase order within EDI. With this message, a buyer places an order digitally with a supplier.

The message is based on the international EDIFACT standard and marks the starting point of the order to cash process. Once received by the supplier, the order is automatically processed in the ERP system. This eliminates manual data entry and significantly reduces errors.

By connecting the EDI platform directly to the ERP system, orders can be exchanged and processed fully automatically. This increases speed, reliability and scalability within the order process.

The ORDERS message therefore forms the basis for subsequent messages such as ORDRSP, DESADV and INVOIC and is an essential component of a fully automated supply chain.

How does an EDI ORDERS message work?
  1. The buyer creates a purchase order in the ERP system.
  2. The EDI solution converts the order into an EDIFACT ORDERS message.
  3. The message is transmitted electronically to the supplier.
  4. The supplier automatically processes the message in the ERP system.
  5. Optionally, the supplier returns an ORDRSP message as order confirmation.

Depending on the agreement, this response can be sent immediately or later.

Who sends and who receives an EDI ORDERS message?

Sender
The buyer, retailer or procurement organisation.

Receiver
The supplier or manufacturer.

What data is contained in an EDI ORDERS message?

An EDIFACT ORDERS message typically contains:

  • Order number
  • Order date
  • Requested delivery date
  • Delivery address
  • Invoice address
  • Contract reference
  • Item information such as GTIN
  • Quantity and unit
  • Pricing information including VAT

This structured data ensures seamless ERP processing on both sides.
