C_TS4FI Financial Accounting Practice Question
Exhibit
Error Log: ACDOCA-GLACC: 100000 Error: Account 100000 requires a cost element. Context: Manual posting to G/L account via FB50.
Refer to the exhibit. Why does the system trigger this error during a manual G/L posting?
⚠ Common exam trap
Candidates often assume errors during G/L postings are exclusively due to authorization issues or incorrect currency keys, missing the structural link between G/L accounts and cost objects in S/4HANA.
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 G/L account is a primary cost element and requires a cost object.
In S/4HANA, the cost element is integrated into the G/L account master record. If a G/L account is defined as a primary cost element, the system mandates a cost object (like a cost center or order) for every posting. This ensures that all primary expenses are traceable to a specific cost object, enabling accurate management accounting and profitability analysis directly from the financial ledger.
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 G/L account is missing a posting key configuration.
Why it's wrong here
Posting keys define the debit or credit nature of a line item but do not govern the requirement for a cost object. This error is specific to the master data attributes of the G/L account, specifically its role as a cost element within the Controlling module integration.
- ✓
The G/L account is a primary cost element and requires a cost object.
Why this is correct
The system identifies the G/L account as a primary cost element, which requires a cost object to ensure proper integration with the Controlling module. Since the user failed to provide a cost center or order, the document validation fails to maintain consistency between Financial and Management Accounting.
- ✗
The fiscal year is not open for the company code.
Why it's wrong here
If the period were closed, the system would return a specific error message stating that the posting period is not open. The provided error specifically mentions the requirement for a cost element, which pertains to master data and Controlling configuration rather than period status control settings.
- ✗
The company code is not assigned to a controlling area.
Why it's wrong here
If the company code lacked a controlling area, the system would raise a different error concerning the inability to initialize the controlling module. The error specifically relates to the missing requirement for a cost element entry, confirming that the Controlling integration is active but incorrectly handled.
