The AAFES 850 Purchase Order, explained

What AAFES expects in the 850

AAFES trades on X12 4010 over VAN. Beyond the base standard, watch these:

How EDISQ maps it

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

Common rejection reasons

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