Rexel USA EDI integration and automation

A guide for suppliers connecting with Rexel USA, covering the documents exchanged, the main program rules, testing and ERP integration.

Overview

Understanding Rexel USA integration

Who this is for: Suppliers that sell to Rexel USA, and the EDI, logistics and finance teams that support them.

Rexel USA is an electrical supply distributor. Suppliers that trade with Rexel USA electronically exchange documents such as the 850 purchase order, 855 purchase order acknowledgment, 856 ship notice/manifest, 810 invoice and 997 functional acknowledgment. This page summarizes how that exchange works from the supplier's side, so your team can scope the work before mapping starts.

The program uses X12 4010. Order types include direct to customer, and distribution center and store. Each order type can change which documents apply and how locations, labels and invoices are handled, so it helps to confirm which ones you will supply before you build anything.

Most of the effort goes into keeping your ERP, warehouse and shipping data consistent with what each document says. Ship notices, labels and invoices need to agree with the original order, and any rule that applies only to one order type needs its own handling in your maps. Rexel USA sets its own requirements and can change them, so treat your account contact and current guide as the final word.
