What Fastenal expects in the 846
Fastenal trades on X12 4010 over AS2. Beyond the base standard, watch these:
How EDISQ maps it
The certified Fastenal 846 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Fastenal's spec before transmission, and the sandbox replays Fastenal test scenarios until everything passes.
Common rejection reasons
Nearly all 846 rejections trace to reference data, not syntax: identifiers that don't match Fastenal's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Fastenal ever sees the document.
