What DECA expects in the 856
DECA trades on X12 4010 over VAN. DECA's 856 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 856 spec before anything transmits.
How EDISQ maps it
The certified DECA 856 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against DECA's spec before transmission, and the sandbox replays DECA test scenarios until everything passes.
Common rejection reasons
Nearly all 856 rejections trace to reference data, not syntax: identifiers that don't match DECA's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before DECA ever sees the document.
