What Grainger expects in the 850
Grainger trades on X12 4010 over AS2. Beyond the base standard, watch these:
How EDISQ maps it
The certified Grainger 850 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Grainger's spec before transmission, and the sandbox replays Grainger test scenarios until everything passes.
Common rejection reasons
Nearly all 850 rejections trace to reference data, not syntax: identifiers that don't match Grainger's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Grainger ever sees the document.
