The Macys 850 Purchase Order, explained

What Macys expects in the 850

Macys trades on X12 4010 over AS2. Beyond the base standard, watch these:

How EDISQ maps it

The certified Macys 850 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Macys's spec before transmission, and the sandbox replays Macys test scenarios until everything passes.

Common rejection reasons

Nearly all 850 rejections trace to reference data, not syntax: identifiers that don't match Macys's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Macys ever sees the document.
