C_TS4FI Financial Accounting Practice Question
Exhibit
TABLE: T001 BUKRS: 1000 PERIV: K4 OPVAR: 1000 CURR: EUR TABLE: T001B BUKRS: 1000 PERIOD: 01 2023 STATUS: LOCKED
Refer to the exhibit. A user attempts to post a vendor invoice in company code 1000 for period 01 2023. Given the configuration state, what is the outcome of the posting attempt?
⚠ Common exam trap
Candidates often assume the system will warn the user but allow the posting. They overlook that table T001B locks are hard stops that trigger errors, preventing the posting entirely.
Answer choices
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 system rejects the posting and triggers an error message regarding the closed period.
The exhibit shows the period 01 2023 is explicitly locked in table T001B. In SAP S/4HANA, the posting control is governed by the posting period variant assigned to the company code. Since the period is locked, the system validation logic will throw a hard error, preventing the document from being saved. This ensures financial integrity by enforcing period-end closing procedures and preventing back-dated entries into closed books.
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 system allows the posting but generates a warning message in the application log.
Why it's wrong here
The status 'LOCKED' in the posting period maintenance implies a restriction that prevents any activity for the specified interval. SAP does not treat this as a warning because allowing postings into locked periods would compromise the accuracy of financial statements prepared for that specific accounting interval during the month-end.
- ✗
The document is posted successfully because the fiscal year variant K4 is active.
Why it's wrong here
The fiscal year variant determines the structure of the periods but does not override the posting period status. Even with a valid fiscal year variant, the explicit lock on the period via transaction OB52 takes precedence, rendering the posting attempt invalid regardless of the underlying calendar setup.
- ✓
The system rejects the posting and triggers an error message regarding the closed period.
Why this is correct
The system checks the T001B table during the posting process. Because the period is set to 'LOCKED', the validation logic encounters a block. This prevents the user from committing the invoice to the Universal Journal, ensuring that no unauthorized entries are made into a period that is already officially closed.
- ✗
The document is saved in the parked status for later approval by the accounting manager.
Why it's wrong here
Parking a document still requires the period to be open for the document date and posting date provided. The system validation logic applies to both parked and posted documents to prevent inconsistencies. Therefore, even parking is blocked when the fiscal period is locked to prevent data manipulation.
