C_TS4FI Financial Accounting Practice Question
Which object acts as the single source of truth for all financial data in SAP S/4HANA?
⚠ Common exam trap
Candidates frequently guess older classic tables like BSEG or BKPF as the single source of truth, forgetting that S/4HANA consolidated everything into the Universal Journal.

Correct answer & explanation
✓
Table ACDOCA
The SAP S/4HANA architecture transitioned from multiple tables to a single unified ledger, the Universal Journal (ACDOCA). This evolution simplifies the data model, enhances performance, and provides a real-time view of financial data. Understanding this table is fundamental for any S/4HANA finance professional, as it replaces separate tables for G/L, CO, Asset Accounting, and Material Ledger, ensuring data consistency across all components.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Table BSEG
Why it's wrong here
BSEG remains as the entry-level table for line item data, but it is no longer the primary source for reporting. S/4HANA utilizes the Universal Journal for high-performance reporting, and BSEG is only accessed when line-item-specific detailed information is required that is not indexed in the primary ledger.
- ✓
Table ACDOCA
Why this is correct
ACDOCA is the Universal Journal where all financial transactions are recorded. It integrates data from G/L, CO, AA, ML, and Profitability Analysis into one central table. This consolidation eliminates data redundancy and reconciliation efforts, serving as the definitive source for all financial reporting within the S/4HANA system.
- ✗
Table FAGLFLEXT
Why it's wrong here
FAGLFLEXT was the total table used in New General Ledger accounting for ECC systems. In S/4HANA, this table is obsolete as the functionality of total tables has been integrated into the Universal Journal, which performs real-time aggregation and eliminates the need for maintaining separate total tables.
- ✗
Table COEP
Why it's wrong here
COEP was the CO line item table in older SAP versions. In S/4HANA, the controlling line items have been moved into the Universal Journal table. Keeping CO data in COEP would result in redundant data storage, which contradicts the simplified data model design of the S/4HANA Finance platform.
