Keep this: job aid

Procurement EDI setup and test card

• 850 out: NAST output NEU, application EF, medium 6, partner function VN; WE20 LI profile ORDERS / ORDERS05 / process code ME10.
• 860 out: ORDCHG line with EF / NEU / ME11 and Change message set; decide output-relevant fields.
• Output control alternative: Output Parameter Determination, PURCHASE_ORDER, role LF, channel EDI; switch via Manage Application Object Type Activation.
• No IDoc after save? Check the PO output log first; a missing partner profile fails the output.
• 855 in: ORDRSP / ORDERS05, process code ORDR (IDOC_INPUT_ORDRSP); PO item needs a confirmation control key (Contoso: 0001).
• A new EDI acknowledgment replaces all earlier ones for the item: suppliers must restate the full picture.
• 856 in: DESADV / DELVRY07, process code DELS (IDOC_INPUT_DESADV1); creates an inbound delivery, LA line if the key expects it.
• Change ASN-created inbound deliveries in VL32N, not in the PO; watch for duplicate ASNs.
• MRP-relevant categories move receipts in planning; GR-relevant LA means receiving against the inbound delivery.
• Test: split and replaced 855s, date tolerance, missing key, partial and excess ASN, duplicates, GR into 171S.
