FICO Central Finance Part 2: Configuration and Document Replication Flow

Key takeaway

Set up Central Finance: system connections and SLT replication, initial load steps (balances, documents, CO), real-time replication, mapping configuration, and how a source document becomes a central journal entry with its reference kept.

Explanation

📌 KEY POINTS
✅ Connect source systems and configure SLT for replication of accounting documents.
✅ Initial load brings historical balances/documents; then real-time replication runs continuously.
✅ Mapping translates source keys (company code, accounts, cost centers) to central values.
✅ Central documents keep a reference to the source document for traceability.
⚠️ Starting real-time replication before mapping is complete floods AIF with errors.

━━━━━━━━━━━━━━━━━━━━
▶ WHERE WE ARE
Part 1 explained the concept. Now configuration.

━━━━━━━━━━━━━━━━━━━━
▶ 1. CONNECTIVITY

RFC, SLT configuration, source registration.

━━━━━━━━━━━━━━━━━━━━
▶ 2. INITIAL LOAD

Preparation, load, validation.

━━━━━━━━━━━━━━━━━━━━
▶ 3. REAL-TIME REPLICATION

Continuous transfer of new postings.

━━━━━━━━━━━━━━━━━━━━
▶ 4. MAPPING SETUP

Key mapping, value mapping, mapping actions.

━━━━━━━━━━━━━━━━━━━━
▶ 5. DOCUMENT FLOW

Source reference kept; drill back.

━━━━━━━━━━━━━━━━━━━━
▶ STEP BY STEP

Configure SLT and source registration.
Maintain mappings.
Run initial load; validate.
Activate real-time replication.

✅ CHECKPOINT: new source postings appear centrally within minutes.

Code example

ABAP Code

===== FLOW =====Source document (BKPF/BSEG) → SLT → Central Finance interface → mapping → central journal entry (ACDOCA) with source reference ===== SETUP ORDER =====Connectivity → mapping (keys/values/actions) → initial load (balances, documents, CO) → validation → real-time replication

Real project scenario

A consumer goods group activated replication before mapping cost centers; thousands of AIF errors appeared. Pausing, completing mapping and reprocessing cleared the backlog.

Common mistakes

Replication before mapping.
Unvalidated initial load.
Ignoring source changes.
No reference checks.
No monitoring.

Best practices

Map first.
Validate loads.
Sync master data changes.
Keep references.
Monitor continuously.

Interview angle

Questions: "How does replication work?", "What is the initial load?", "What does mapping do?"
Strong answer: connectivity, load, real-time, mapping, references.

Practice this lesson

Quick check

1. Before real-time replication is switched on for a source system in a Central Finance implementation, which process is used to bring already-posted historical documents into the Central Finance system?

2. Thousands of replication errors appeared right after activation. What was likely done wrong?

3. Which SAP component is typically used to harmonize and consolidate master data (such as customers, vendors, and G/L accounts) from multiple source systems before or during Central Finance replication?

Interview questions

1. How would you apply Central Finance in a real SAP project? Walk through the design or implementation approach.

Answer it in your own words first, then compare.

2. Plan the configuration and go-live of Central Finance replication for three source systems.
