How do EDI Systems Work?

  1. Data Preparation
  • Conversion to EDI Format: The first step involves converting a business document (like a purchase order, invoice, or shipping notice) into an EDI format. This is done by mapping the data from the company’s internal system (e.g., ERP, CRM, or accounting software) into the required EDI standard (such as ANSI X12, EDIFACT, or XML).
  • EDI Standards: EDI standards specify the format and data elements required for each type of document. These standards ensure that all parties involved understand and can process the information accurately.
  1. Transmission
  • Communication Protocols: The EDI document is then transmitted to the trading partner using secure communication protocols. Common protocols include:
  •  

    • AS2 (Applicability Statement 2): A widely used protocol that securely transmits EDI documents over the internet.
    • FTP/SFTP: File Transfer Protocols, either with or without security enhancements, used for sending files between systems.
    • VAN (Value Added Network): A third-party service provider that facilitates the exchange of EDI documents between trading partners.
    • Web EDI: An internet-based platform where users can upload or receive EDI documents through a web interface.
  • Encryption: During transmission, the data is often encrypted to ensure security and compliance with industry regulations.
  1. Data Reception
  • Validation: Upon receiving the EDI document, the recipient’s EDI software validates the data against the predefined EDI standard. This step checks for errors, completeness, and compliance with the format.
