C_TS4FI Financial Accounting Practice Question
When migrating to SAP S/4HANA, which activities are mandatory for the Financial Accounting data migration?

Correct answer & explanation
✓
Reconciling open items and balances between legacy and target systems.
Data migration is the most critical phase of an S/4HANA transition. It requires precise synchronization between the source system and the target S/4HANA environment. Ensuring the consistency of open items, closing balances, and master data is essential for the system to function correctly. These steps ensure that the financial integrity is maintained and that the new ledger structure can accurately reflect the company's historical financial position.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Migrating every historical document from the legacy system.
Why it's wrong here
Migrating every historical document is not required and is technically inefficient. SAP best practices suggest migrating only open items and account balances. Keeping historical document data in an archive system is standard procedure to reduce the database footprint and optimize the performance of the new S/4HANA environment.
- ✓
Reconciling open items and balances between legacy and target systems.
Why this is correct
Reconciliation is the fundamental requirement for a successful financial migration. It ensures that the opening balances in the new S/4HANA system match the final balances in the legacy system. Without this validation, the financial statements generated in S/4HANA would be inaccurate, violating fundamental accounting and audit requirements.
- ✗
Manually creating all cost elements as G/L accounts.
Why it's wrong here
In S/4HANA, the migration cockpit automates the transition of cost elements into the G/L master records. Manual creation is unnecessary and prone to errors. Using the migration tool ensures that all necessary technical fields and attributes are correctly mapped according to the updated S/4HANA data model.
- ✗
Changing the chart of accounts during the migration process.
Why it's wrong here
While it is possible to change the chart of accounts, it is not mandatory for the migration itself. Many companies perform a chart of accounts redesign as a separate project or during the migration phase, but it is not a requirement for the technical migration of financial data.
