What ALDI expects in the 855

ALDI trades on X12 4010 over AS2. ALDI's 855 follows the standard X12 layout — no partner-specific companion-guide quirks are curated for this document yet. The certified base map covers the standard requirements, and validation still runs against the 855 spec before anything transmits.

How EDISQ maps it

The certified ALDI 855 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against ALDI's spec before transmission, and the sandbox replays ALDI test scenarios until everything passes.

Common rejection reasons

Nearly all 855 rejections trace to reference data, not syntax: identifiers that don't match ALDI's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before ALDI ever sees the document.
