Lawson-Supported EDI transactions

Lawson currently provides six EDI transactions for its healthcare EDI customers (the ASC X12 number is shown in parentheses):

  • Purchase orders (850)

    The basic transaction for all EDI purchasing is the electronic purchase order. With electronic purchase orders, EDI users can order materials from vendors electronically.

  • Purchase order acknowledgments (855)

    After receiving a purchase order, the vendor returns a detailed purchase order acknowledgment to the client. This acknowledgment summarizes the information about the purchase order and validates the order's authenticity.

  • Price/sales catalogs (832)

    Throughout the purchasing process, the supplier should repeatedly send the client price/sales catalogs. These catalogs are EDI transactions that contain detailed ordering information. The catalogs update the client's computer system with current item numbers and prices for available sales items.

  • Advance ship notification (856)

    Before sending an order shipment, a supplier or vendor can send an advance ship notice using EDI. This ship notification gives the client detailed information about the contents of an upcoming shipment.

  • Invoices (810)

    After a shipment is received, vendors send their clients electronic invoices, which are electronic bills for materials and services.

  • Functional acknowledgments (997)

    Functional acknowledgments confirm the receipt of EDI transactions. If a client and vendor use functional acknowledgments, they will be sending or receiving an acknowledgment for each of their EDI transactions. The vendor would send a functional acknowledgment for every purchase order they receive, and receive an acknowledgment for every transaction they send.

  • Product Transfer and Resale Report (867)

    The Product Transfer and Resale Report reports on the distribution and returns of product from the central distribution center to the clinic or hospital.
