C_TS4FI Financial Accounting Practice Question
Your company posts a vendor invoice for office supplies to a cost center in SAP S/4HANA. The accounts payable accountant notices that the expense line item automatically contains a profit center and segment, even though the vendor invoice was entered without any profit center or segment information. Which configuration enables this automatic derivation?
⚠ Common exam trap
The trap here is assuming that profit center and segment must be entered manually on every expense line, when in fact the cost center master record drives the derivation automatically.

Correct answer & explanation
✓
Profit center derivation from the cost center master record
In SAP S/4HANA, posting an expense to a cost center automatically derives the profit center from the cost center master record. Since profit centers are assigned to segments, the segment is also populated. This real-time integration ensures that profitability and segment reporting reflect the correct organizational units without manual data entry, which is why the expense line contains both profit center and segment despite none being entered.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Profit center derivation from the cost center master record
Why this is correct
The cost center master record contains a profit center assignment. When a cost center is entered on an expense line item, the system derives the profit center from that master record and, because the profit center is assigned to a segment, the segment is also derived. This is standard real-time integration between Controlling and Financial Accounting in SAP S/4HANA, ensuring consistent reporting without manual entry.
- ✗
Default profit center maintained in the company code global parameters
Why it's wrong here
Company code global parameters hold settings such as the chart of accounts, fiscal year variant, and field status variant. They do not contain a default profit center for expense postings. Profit center derivation is driven by the cost center master, not by company code-level defaults, so this configuration would not produce the observed automatic assignment on a cost center expense line.
- ✗
Substitution rule triggered by the cost center field in the line item
Why it's wrong here
Substitution rules (GGB1) can derive values, but they are custom validation/replacement rules that must be explicitly created and activated. The scenario describes standard behavior observed without mention of custom substitutions. The automatic profit center and segment derivation is a delivered integration feature, not a substitution rule, so this option misidentifies the mechanism.
- ✗
Automatic account assignment configured in the vendor master record
Why it's wrong here
The vendor master contains payment terms, reconciliation accounts, and bank details, but it does not carry profit center or segment defaults for expense lines. Vendor master data is used to determine the reconciliation account and payment behavior, not the profit center of the offsetting expense. Therefore, it cannot explain the automatic derivation seen on the expense line.
