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