Controlling foundation

This page explains why PHASE 4 matters for SAP S/4HANA Controlling design in the FIT 4 SAP prototype. In short, you define the financial “nervous system” that keeps every cost, revenue, and valuation posting consistent, traceable, and truthful. It matters because every later process — procurement, production, sales, planning — collapses without a clean controlling foundation. Use this phase when you need internal reporting that matches reality, and avoid it when you think FI alone can carry the weight (it cannot).

Step 04-14: Why do Cost Elements decide whether your numbers are facts or fiction?

Step 04-15: Why do Number Ranges decide your controlling documents can be trusted?

The Principle

If FI tells the story of what happened, CO explains why it happened and who is responsible for it.
