What Big Lots expects in the 850
Big Lots trades on X12 4010 over AS2. Beyond the base standard, watch these:
How EDISQ maps it
The certified Big Lots 850 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Big Lots's spec before transmission, and the sandbox replays Big Lots test scenarios until everything passes.
Common rejection reasons
Nearly all 850 rejections trace to reference data, not syntax: identifiers that don't match Big Lots's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Big Lots ever sees the document.
