Infor M3 Migration Reconciliation — Auditor-Grade Sign-Off

Infor m3 migration reconciliation is the auditor-grade discipline of proving that M3 source data and Oracle Fusion target data agree at every level that finance, tax, statutory reporting, supply chain ops and quality care about. Validation (which runs continuously inside the pipeline) catches technical errors; reconciliation produces the periodic signed evidence pack that says 'every M3 GL posting for CONO 100 period 2025-12 is accounted for in Fusion GL — full stop'. The reconciliation framework reconciles trial balance, AP aging, AR aging, inventory valuation, lot/serial counts, sales-order open balances, PO open balances, and inter-company (CRS165) per-counterparty pair. Threshold is zero variance. Sign-off is finance, audit, supply-chain and quality leads.

Inter-company is where most M3 migrations break finance trust late in the cycle. M3 inter-company postings flow through CRS165 with linked FGL entries — when Nordic CONO 100 invoices Continental CONO 200 for an inter-company transfer, both sides post simultaneously and must reconcile to the cent at every period close. The infor m3 migration reconciliation framework treats inter-company as a first-class dimension: per period, per CONO-pair, per currency, the framework reconciles M3-side posting against Fusion-side counterparty posting, identifies any difference, classifies cause (timing, FX, rounding, missed mapping), and produces per-pair drill-down. Finance signs off per pair before any pair is allowed to advance to the next period.

Customers with EU CONOs subject to SAF-T (Portuguese, Norwegian, Luxembourg, French FEC, Polish JPK, Hungarian Online Invoice and others) need the migration to preserve the audit-lineage from GL line back to source document. The infor m3 migration reconciliation framework runs jurisdiction-aware checks per relevant CONO: SAF-T-expected fields populated, audit-trail integrity verified, source-document traceability preserved end-to-end. For each jurisdiction, the reconciliation deliverable includes a SAF-T pre-flight pass — a structured extract from Fusion that matches what the country's tax authority would request, validated against M3's equivalent extract, so go-live tax-filing produces identical statutory output.

German entities under HGB are required to retain accounting records for 10 years with auditor access on demand. The infor m3 migration reconciliation framework treats HGB-applicable CONOs specially: 10 years of GL postings preserved (typically in long-term Syntra cloud archive when not migrated to Fusion), audit-trail integrity validated per posting, GoBD (German principles for orderly bookkeeping) compliance verified, and the long-term storage strategy signed by tax. Migration reconciliation includes a HGB pre-flight: a structured archive index of every retained German posting per CONO per year, with verified audit-trail chain back to source M3 voucher and beyond to AP/AR/inventory document. Tax signs the pre-flight before sign-off.

Food, beverage and pharma customers running FDA 21 CFR Part 11 have non-negotiable recall-traceability requirements. The infor m3 migration reconciliation framework runs end-to-end lot-genealogy reconciliation: per sampled finished-lot in Fusion, walk the chain back to received raw material lots; per equivalent finished-lot in M3, walk the same chain; chains must match exactly. Lot count per item per warehouse reconciled. Quality status, expiration, manufacture, country-of-origin, supplier-lot reconciled. FDA Part 11 electronic signatures verified intact. Quality leads sign per CONO per vertical before sign-off. Recall query replay is the killer test — if it doesn't produce identical output on both sides, the load is rejected.

Modifications classified during assessment as 'replace with Fusion DFF' carry custom data into Fusion descriptive flexfields. The infor m3 migration reconciliation framework reads the signed crosswalk register, identifies every mod-extended field that maps to a Fusion DFF, and runs row-level field-equality reconciliation on every record. Mods classified as 'retire' (data not migrated) generate a confirmation report — explicit evidence that zero records were migrated for the retired field, with sign-off from the business owner who made the retire decision. Mods classified as 'rebuild as custom' are validated against the rebuilt Fusion extension's data model — typically VBCS-stored or OIC-routed.

The continuous validation pipeline runs in 8–12 hours per full-scope load. The periodic reconciliation framework — the signed evidence pack for period sign-off — typically runs in 4–8 hours per CONO per period: GL trial balance reconcile (1–2 hours), AP aging reconcile (30 min), AR aging reconcile (30 min), inventory valuation reconcile (1–2 hours), lot/serial reconcile (1–2 hours), inter-company reconcile per counterparty pair (30 min per pair), SAF-T and HGB pre-flights (30 min per applicable CONO). A 5-CONO multi-jurisdiction tenant typically completes monthly reconciliation in 2–3 calendar days end to end, with finance, tax, ops and quality signing in sequence.

Variances post-cutover are rare when the validation pipeline has done its job — but the framework is built to handle them. The infor m3 migration reconciliation engine retains the M3 source extract for the retention window (typically 12 months minimum), so any post-cutover variance can be re-extracted, re-validated and root-caused without re-engaging the source M3 BE. Classification of variance into root-cause categories (crosswalk drift, late delta replay, timing, FX, manual Fusion adjustment) is automated. Resolution path is documented (corrective Fusion journal, supplemental data load, or business-process correction). Every variance and its resolution flows into the audit log for the next reconciliation cycle.
