The SSI EDI Standard

Testing EDI 850 for SSI should include sample documents, required segments, validation rules, acknowledgments and exception scenarios. The goal is to confirm that the purchase order workflow works correctly before production traffic starts.

The first workflows for SSI should usually be the documents that drive production, order, shipment and invoice workflows. In practice, this means starting with 810, 850, 855 and 856, then adding optional documents such as 812, 820, 824, 846, 860, 861 and 870 when the business process requires them.

SSI EDI documents can fail testing because of missing required segments, invalid identifiers, incorrect dates, bad item references, quantity mismatches, totals that do not balance or documents sent through the wrong communication setup. This is especially important for all product and supply-chain industries where partner requirements can affect downstream teams.

Barcode labels and ASN processing should be aligned so the receiving team can match physical cartons to EDI shipment data. For SSI, this usually means testing label values, shipment references and the 856 ASN together.

Partner identifiers should be validated in envelopes, headers, map logic and the connected system. For SSI, incorrect sender or receiver IDs can cause files to fail before the business document is even processed.

SSI EDI should connect with accounting and finance systems when those platforms manage invoice posting, payment reconciliation, remittance advice and financial exception handling. The integration should keep EDI documents, business rules, acknowledgments and exception handling aligned.

Testing should confirm required segments, partner identifiers, document references, dates, item data, quantities, totals, acknowledgments and posting in the connected system. This applies across 810, 850, 855 and 856 and optional workflows.

Manual rekeying can be reduced by mapping 810, 850, 855 and 856 into the right ERP, WMS, TMS, eCommerce, accounting or shipping system. The map should also handle exceptions and acknowledgments clearly.
