What Loblaw expects in the 856
Loblaw trades on X12 4010 over AS2. Beyond the base standard, watch these:
How EDISQ maps it
The certified Loblaw 856 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Loblaw's spec before transmission, and the sandbox replays Loblaw test scenarios until everything passes.
Common rejection reasons
Nearly all 856 rejections trace to reference data, not syntax: identifiers that don't match Loblaw's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Loblaw ever sees the document.
