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