Electronic Data Interchange
EDIElectronic Data Interchange (EDI) is the computer-to-computer exchange of business documents in a standard electronic format.
Electronic Data Interchange (EDI) replaces paper-based or manual electronic documents like purchase orders and invoices with a standardized digital format. This allows different companies' computer systems to communicate directly without human intervention. For example, instead of emailing a PDF purchase order, a customer's ERP system sends an EDI file directly to a supplier's ERP system.
EDI works by translating business documents into a standard format. Common standards include ANSI X12 in North America and EDIFACT internationally. A company's system generates a document, such as an invoice. EDI software then converts this document into a structured EDI file. This file is sent to the trading partner through a secure network, like a Value-Added Network (VAN) or a direct connection (AS2). The receiving system's EDI software translates the file back into a format its internal applications can process.
On the shop floor, EDI automates the start of the production process. An incoming EDI purchase order can automatically create a sales order and a work order in the manufacturing execution system (MES). This reduces data entry errors and shortens the time from order receipt to production start. It also improves inventory management. Suppliers can send an Advance Ship Notice (ASN) via EDI, giving the receiving plant exact details about an incoming shipment before it arrives.
Manufacturers implement EDI to meet the requirements of large customers, especially in industries like automotive and retail. Implementation involves choosing an EDI solution, which could be on-premise software or a cloud-based service. Companies must then establish connections with their trading partners. This includes mapping their internal data fields to the standard EDI segments and elements for each document type.
An automotive parts supplier receives an EDI 850 (Purchase Order) from a car manufacturer. Their ERP system automatically processes the order and schedules production. Once the parts are shipped, the supplier sends an EDI 856 (Advance Ship Notice) to the manufacturer, detailing the shipment's contents and arrival time.
What is the difference between EDI and an API?
EDI exchanges batches of structured documents like purchase orders in a standardized format. An API allows different software applications to communicate with each other in real-time for more varied tasks.
Is EDI required for all manufacturers?
No, but many large retailers and OEMs require their suppliers to use EDI. It is a common requirement for doing business in certain supply chains.
What are the most common EDI documents in manufacturing?
Common documents include the 850 (Purchase Order), 856 (Advance Ship Notice), 810 (Invoice), and 830 (Planning Schedule with Release Capability).
Can a small manufacturer afford to use EDI?
Yes. Many small businesses use web-based EDI portals or managed services. These options reduce the initial investment in software and infrastructure.
What is a Value-Added Network (VAN)?
A VAN is a private network that handles EDI communications between trading partners. It acts like a digital post office, ensuring secure and reliable document exchange.
