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