How EDISQ maps it
The certified Chemist Warehouse 855 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Chemist Warehouse's spec before transmission, and the sandbox replays Chemist Warehouse test scenarios until everything passes.
Common rejection reasons
Nearly all 855 rejections trace to reference data, not syntax: identifiers that don't match Chemist Warehouse's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Chemist Warehouse ever sees the document.
