MSC Industrial Supply EDI integration and automation

A guide for suppliers connecting with MSC Industrial Supply, covering the documents exchanged, the main program rules, testing and ERP integration.

Overview

Understanding MSC Industrial Supply integration

Who this is for: Suppliers that sell to MSC Industrial Supply, and the EDI, logistics and finance teams that support them.

MSC Industrial Supply is a distributor of metalworking tools and MRO supplies. Suppliers that trade with MSC Industrial Supply electronically exchange documents such as the 850 purchase order, 855 purchase order acknowledgment, 860 purchase order change, 865 purchase order change acknowledgment and 856 ship notice/manifest. 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, with 5010 for routing. Order types include direct to customer, and distribution center and fulfillment center. 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. MSC Industrial Supply sets its own requirements and can change them, so treat your account contact and current guide as the final word.
