The UN/EDIFACT ORDERS is a Purchase Order Format sent from customers to suppliers, asking for goods or services. An EDI (Electronic Data Interchange) purchase order message is a core business document for automated B2B document exchange that comes along with most EDI workflows.
Buying organizations use EDI purchase orders to order services or goods and direct them to distribution centers, stores or their end consumers.
The ORDERS format is the purchase order document using EDI messaging standards based on EDIFACT as a common EDI standard format.
The purchase order is normally created in the ERP system of the customer in an ERP-specific data format. Using an EDI solution this internal format then is converted into the EDIFACT ORDERS format. After the conversion, the message is sent to the supplier placing an order for goods or services.
The purchase order information follows a structure of so called segments and elements specified for EDIFACT ORDERS. An EDI purchase order message document like EDIFACT ORDERS is sent, received, and processed by an EDI solution (either using EDI software on-premises or in making use of an EDI Cloud Service). To ensure a smooth, automated process, it is mandatory to follow the accepted EDIFACT ORDERS standards or otherwise this may create errors or even prevent the document from ever arriving at the supplier.
Content of a typical EDIFACT ORDERS Message contains:
Upon receiving the EDIFACT ORDERS message, the supplier will validate the document against the EDIFACT ORDERS standards specification and provide a functional acknowledgement (EDIFACT CONTROL). The objective of such a functional acknowledgment is the confirmation of the purchase order receipt.
Documents that are exchanged between customer and supplier EDI trading partners follow a standard sequence of business processes, which varies depending on the type of vertical industry. The figure below shows the role of an EDIFACT ORDERS message and which other message types are used in a retail scenario:
EDIFACT is the standard proposed by the UN, and is widespread in Europe as well as most parts of Asia. UN/EDIFACT uses a single ORDERS document to cover all purchase order messages.
Depending on industries and geographies other EDI message standards might be preferred, for example:
The ANSI X12 standard is widely used in North America, and has two EDI purchase order document types, the 850 (CPG Retail) and 875 (for fresh foods like grocery). TRADACOMS is a standard in the UK retail sector still in use and the TRADACOMS purchase order message is called ORDHDR.
The efficiency of the day-to-day EDI workflow depends on the quality of the data involved. Typical challenges are new sets of data in the customer ERP system, which are not known in the supplier ERP system in time and result in conflicts with the ORDERS Purchase Order Message:
This production and delivery processes can be much more streamlined. This way customers and suppliers can work with smaller inventories and can for example establish Vendor Managed Inventory (VMI) retailing.
