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