C_TS4FI Financial Accounting Practice Question
You are testing a new posting in SAP S/4HANA Financial Accounting. After entering a document with a posting date of July 15, the system displays an error: "Posting period 07 2025 is not open for account type S." Where do you check and, if authorized, open the posting period for this account type?
⚠ Common exam trap
Many candidates confuse the configuration of posting period variants (OBBO) with the actual opening and closing of periods (OB52).
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
✓
In the 'Open and Close Posting Periods' app or transaction OB52, by maintaining the period range for account type S.
The error indicates that the posting period for account type S is closed. Posting periods are controlled per account type and period in OB52 or the Fiori app 'Open and Close Posting Periods'. By adding or extending the interval to include July 2025 for account type S, the posting can be made. Other configurations like fiscal year variants or tolerance groups do not govern period opening.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
In the tolerance group configuration for the user using transaction OBA4.
Why it's wrong here
Tolerance groups (OBA4) define permissible payment differences and cash discount tolerances for users. They have no bearing on whether a posting period is open for a particular account type. The error explicitly refers to the posting period, so tolerance group settings are irrelevant here.
- ✗
In the fiscal year variant configuration using transaction OB29.
Why it's wrong here
Transaction OB29 is used to define and maintain fiscal year variants, which determine the number of posting periods and special periods. It does not control whether a specific period is open for posting for a given account type. Changing the fiscal year variant would affect the entire company code and is not the appropriate fix.
- ✓
In the 'Open and Close Posting Periods' app or transaction OB52, by maintaining the period range for account type S.
Why this is correct
OB52 (or the corresponding Fiori app) is the correct place to open and close posting periods for each account type. For account type S (G/L accounts), you must ensure that the period interval includes July 2025. This directly addresses the error message and allows the posting to proceed.
- ✗
In the company code global parameters under 'Posting Periods' using transaction OBBO.
Why it's wrong here
Transaction OBBO is used to define variants for posting periods, not to open or close them. While it is part of the posting period configuration, it does not control the open/closed status for a specific period and account type. Therefore, it cannot resolve the error in this scenario.
