How EDISQ maps it
The certified Patterson Veterinary 850 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Patterson Veterinary's spec before transmission, and the sandbox replays Patterson Veterinary test scenarios until everything passes.
Common rejection reasons
Nearly all 850 rejections trace to reference data, not syntax: identifiers that don't match Patterson Veterinary's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Patterson Veterinary ever sees the document.
