C_TS4FI Financial Accounting Practice Question
During a foreign currency vendor invoice posting in SAP S/4HANA Finance, the accountant notices that the exchange rate used by the system differs from the rate the accountant expected. The invoice is posted in USD with the local currency being EUR. The exchange rate was determined automatically based on the posting date. Which configuration object is responsible for the exchange rate determination, and where should the accountant verify the rate used?
⚠ Common exam trap
The trap here is assuming that exchange rates are configured in company code global parameters or posting period settings rather than in the dedicated exchange rate table accessed via OB08.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The exchange rate type maintained in Customizing, verified in the currency exchange rates table via transaction OB08.
Exchange rates in SAP S/4HANA Finance are maintained by exchange rate type, currency pair, and validity date using transaction OB08. The system determines the rate for a foreign currency posting based on the exchange rate type configured for the document or company code and the posting date. Verifying the rate in OB08 for the relevant exchange rate type and date confirms which rate the system applied.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The currency translation ratios defined in the company code global parameters, verified in transaction OY01.
Why it's wrong here
Currency translation ratios are used to convert between currencies with different decimal places, but they do not determine the actual exchange rate applied to a posting. Transaction OY01 is used for country-specific settings, not for displaying exchange rates. The exchange rate itself is stored in the exchange rate table and maintained via OB08, so this option does not correctly identify the object or the verification transaction for the scenario.
- ✗
The valuation area settings in Asset Accounting, verified in transaction OAYZ.
Why it's wrong here
Valuation areas in Asset Accounting define how assets are valued for different purposes, such as book depreciation or tax depreciation. They are not involved in determining exchange rates for vendor invoice postings in Financial Accounting. Transaction OAYZ is used for asset accounting configuration, not for currency exchange rate determination, so this option is irrelevant to the foreign currency invoice posting scenario described.
- ✓
The exchange rate type maintained in Customizing, verified in the currency exchange rates table via transaction OB08.
Why this is correct
Exchange rates are stored by exchange rate type, currency pair, and validity date in the SAP S/4HANA Finance currency tables. Transaction OB08 is the standard transaction for entering and displaying exchange rates. The system determines the rate based on the exchange rate type assigned in the document type or company code settings, the currencies involved, and the posting date. Verifying the rate in OB08 for the correct exchange rate type and date allows the accountant to confirm or correct the rate used for the posting.
- ✗
The posting period variant assigned to the company code, verified in transaction OBBO.
Why it's wrong here
The posting period variant controls which posting periods are open for which account types; it does not determine exchange rates. Transaction OBBO is used to maintain posting period variants. While the posting period variant affects whether a posting is allowed in a given period, it has no influence on the exchange rate applied. Therefore, this option does not address the exchange rate discrepancy the accountant is investigating.
