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