What MSC Industrial Supply expects in the 855

MSC Industrial Supply trades on X12 4010 over AS2. MSC Industrial Supply's 855 follows the standard X12 layout — no partner-specific companion-guide quirks are curated for this document yet. The certified base map covers the standard requirements, and validation still runs against the 855 spec before anything transmits.

How EDISQ maps it

The certified MSC Industrial Supply 855 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against MSC Industrial Supply's spec before transmission, and the sandbox replays MSC Industrial Supply test scenarios until everything passes.

Common rejection reasons

Nearly all 855 rejections trace to reference data, not syntax: identifiers that don't match MSC Industrial Supply's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before MSC Industrial Supply ever sees the document.
