I. Introduction

The WISL EDI - Retail module(EDIR) provides the framework for receiving and transmitting standard Retail EDI transaction sets. EDIR provides the required control to enable monitoring and review of the transmission process. It performs editing upon incoming EDI batches to ensure conformance with EDI standards. EDIR writes the valid transactions into the corresponding transaction hold files and generates and sends appropriate EDI response transactions.

The transactions are stored in the hold files in formats that are readily convertible to the internal format of any application utilizing the UNIVERSE data base management system. Standard ASCII fixed or variable length records may also be easily generated from the hold file records to be used with any UNIX or Windows/NT based application.

The EDIR facility also assembles EDI transaction sets from records marked as outbound in the hold files into batches for transmission. The formats of the hold file records have been designed to facilitate conversion from application specific format.

All transmissions are stored until cleared by functional acknowledgement and a log is maintained of all transaction traffic by partner. The log contains sufficient identification information to allow recreation of an EDI transaction batch by an application.

EDIR utilizes standard UNIX UUCP protocol to establish communication with either networks or individual partners.

EDIR currently handles the following standard Retail EDI transaction sets:

Set 810 Invoice

Set 820 Payment/Order Remittance Advice

Set 850 Purchase Order
