FICO Central Finance Part 3: Mapping and Reconciliation Controls
Keep Central Finance reliable: key vs value mapping, mapping actions (keep, map, clear), master data synchronization (often with MDG), cost object mapping, and reconciliation reports comparing source and central balances and documents.
Explanation
📌 KEY POINTS
✅ Key mapping maps master data IDs (e.g. customer, supplier, material); value mapping maps codes (e.g. company code, payment terms).
✅ Mapping actions decide per field: keep source value, map, or clear.
✅ Master data governance (e.g. MDG) keeps mappings in sync with source changes.
✅ Reconciliation compares source vs central balances and document counts regularly.
⚠️ Mapping maintained manually without ownership degrades quickly.
━━━━━━━━━━━━━━━━━━━━
▶ WHERE WE ARE
Part 2 configured replication. Now controls.
━━━━━━━━━━━━━━━━━━━━
▶ 1. KEY VS VALUE MAPPING
- IDs vs codes.
━━━━━━━━━━━━━━━━━━━━
▶ 2. MAPPING ACTIONS
- Keep, map, clear.
━━━━━━━━━━━━━━━━━━━━
▶ 3. MASTER DATA SYNC
- MDG or controlled processes.
━━━━━━━━━━━━━━━━━━━━
▶ 4. COST OBJECTS
- Cost center/order mapping.
━━━━━━━━━━━━━━━━━━━━
▶ 5. RECONCILIATION
- Balance and document comparisons; exceptions.
━━━━━━━━━━━━━━━━━━━━
▶ STEP BY STEP
- Review mapping per entity.
- Set actions per field.
- Run reconciliation and analyse differences.
✅ CHECKPOINT: differences explained daily.
Code example
===== MAPPING EXAMPLES =====Key mapping: source supplier 100234 → central BP 5000123Value mapping: source company code 1000 → central 1010 | payment term Z30 → N030Mapping action: profit center = map | text field = keep | obsolete field = clear ===== RECONCILIATION =====Source vs central: balances per company code/account | document counts per dayReal project scenario
A new source profit center had no mapping; its postings failed centrally for a week. Adding a master data sync rule for new profit centers and daily reconciliation ended silent gaps.
Common mistakes
- Unowned mappings.
- No sync for new master data.
- Wrong actions.
- No reconciliation.
- Ignoring cost objects.
Best practices
- Assign owners.
- Sync via governance.
- Review actions.
- Daily reconciliation.
- Map cost objects.
Interview angle
Questions: "Key vs value mapping?", "What are mapping actions?", "How do you reconcile source and central?"
Strong answer: mapping types, actions, sync, cost objects, reconciliation.
