SAP Integration Advisor: MIGs, MAGs and AI-Proposed B2B Mappings

Keep this: job aid

Integration Advisor MIG and MAG checklist

• Start from the partner's spec: type system, message, version (for example ASC X12 850 004010) and envelope.
• Create the MIG from 10-25 real partner files (EDI flat file ZIP) so nodes and qualifiers are auto-selected.
• Set direction from the B2B view (inbound 850 and its ORDERS05 target are both In) and at least one business context value.
• Qualify generic segments (N1 BY, N1 ST; PO1 BP, VP), cut codelists to used values, add notes that cite spec page and version.
• Simulate each MIG with real payloads; resolve every node the MIG doesn't define.
• Build the MAG; accept a proposal only with a spec reference, and document rejections.
• Test with expected target payloads: zero differences, repeating groups, every qualifier and code value, negative files.
• Activate MIGs, then the MAG; export or inject runtime artifacts; check the complete-message-XSD setting.
• In TPM: profiles, template transactions with MIG and MAG, agreement, Activate; use Update MIGs/MAGs for new versions.
• Change only through a new draft version; export PDF documentation and keep test evidence per version.
