What Core-Mark expects in the 810
Core-Mark trades on X12 4010 over AS2. Beyond the base standard, watch these:
How EDISQ maps it
The certified Core-Mark 810 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Core-Mark's spec before transmission, and the sandbox replays Core-Mark test scenarios until everything passes.
Common rejection reasons
Nearly all 810 rejections trace to reference data, not syntax: identifiers that don't match Core-Mark's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Core-Mark ever sees the document.
