What REI expects in the 810
REI trades on X12 4010 over AS2. REI's 810 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 810 spec before anything transmits.
How EDISQ maps it
The certified REI 810 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against REI's spec before transmission, and the sandbox replays REI test scenarios until everything passes.
Common rejection reasons
Nearly all 810 rejections trace to reference data, not syntax: identifiers that don't match REI's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before REI ever sees the document.
