C_TS4FI Exam Questions: Free SAP System Tasks [2026]

Process Flow:

• Analyze the legacy classical ABAP extensions (Tier 3) identified by the ABAP Test Cockpit and Custom Code Migration app.
• Identify which custom developments can be completely replaced by standard SAP Fiori apps or Key User In-App Extensibility tools (Tier 1).
• For required custom ABAP code, map it to the ABAP Cloud development model using only released SAP APIs and objects (Tier 1).
• For custom code requiring unreleased SAP objects, design a custom wrapper (Tier 2) to bridge the gap until a released API becomes available.
• Plan the decoupling of complex or highly specialized applications using SAP Business Technology Platform for side-by-side extensibility.

Expected Outcome: A finalized extensibility architecture document that outlines the transition from classical ABAP to Tier 1 and Tier 2 extensions, ensuring the resulting system is lifecycle-stable and cloud-ready.

Common Mistakes:

• Applying classical ABAP extensions directly into the SAP S/4HANA Cloud system, which violates the Clean Core model and complicates future release upgrades.
• Failing to utilize SAP Business Technology Platform for complex side-by-side extensions, thereby overloading the core ERP system.

Exam Insight:

• Tests advanced knowledge of the Three-Tier Extensibility Model and the strategic implementation of the "Clean Core" concept.
• Essential for understanding how to properly govern, modernize, and decouple custom code during an SAP Activate system conversion.

Step-by-Step Execution:

1. Copy the standard correspondence type SAP01 (Payment notice) to create a customized user-defined correspondence type.
2. Assign the relevant print program (RFKORD00) and selection variant to the new correspondence type.
3. Navigate to the reason code configuration and select the According to Reason Code checkbox.
4. Assign the newly created correspondence type specifically to the Miscellaneous Deduction (MD) reason code.
5. Save the configuration to ensure the specific letter is triggered during payment settlement.

Example Values:

• Standard Correspondence Type: SAP01
• Reason Code: MD (Miscellaneous Deduction)

Expected Result: When a residual item is created with the MD reason code, the system automatically requests the custom payment notice correspondence type instead of the tolerance group default.

Quick Mistakes:

• Modifying the standard SAP01 correspondence type directly instead of copying it, which risks it being overwritten during a system upgrade.
• Forgetting to assign the print program (RFKORD00) or form ID to the selection variant, resulting in a print failure.
• Not checking the According to Reason Code box, causing the system to ignore the reason code link.

Exam Insight:

• Tests the understanding of correspondence types, print programs, and reason code linkages.
• Highlights that reason code correspondence overrides the default payment notice assigned to the tolerance group, provided all reason codes in the document share the same correspondence type.

Step-by-Step Execution:

1. Select the Business Catalog where you wish to place the reference.
2. Click the Add Tiles/Target Mappings button and choose Add Tiles/TMs to Selected Catalog.
3. Locate the application in the Tiles/Target Mappings tab by searching for a property such as App ID or Title.
4. Select the line containing the Tile and Target Mapping (Tile + TM).
5. Click the Add Tile/TM Reference button to insert the full app descriptor into the Business Catalog.

Example Values:

• App ID: F2814 (Manage KPIs and Reports)

Expected Result: The app descriptor reference is successfully added to the Business Catalog without creating a new technical definition.

Quick Mistakes:

• Using the Launchpad Designer to create original definitions instead of just referencing them, which violates the recommended practice of keeping definitions strictly in Technical Catalogs.
• Applying client-specific changes in the configuration scope (/UI2/FLPCM_CONF) instead of the customizing scope (/UI2/FLPCM_CUST).

Exam Insight:

• Tests the architectural rule that Business Catalogs control user access and should only contain references, while Technical Catalogs hold the actual definitions.
• Important for maintaining lifecycle-stable launchpad content administration.

Resolution:

• Verify that if multiple reason codes are used on a single document, they all share the exact same correspondence type.
• Alternatively, assign a universally applicable payment notice to the tolerance group to handle multi-deduction scenarios.

Prevention Tip: Keep deduction logging simple per payment or align the Customizing of correspondence types across frequently used reason codes.

Resolution:

1. Navigate to Customizing for General Ledger Accounting under Master Data.
2. Select Preparations and choose Define Retained Earnings Account.
3. Define the required retained earnings account and run the balance carryforward program (FAGLGVTR) again.

Prevention Tip: Always verify that retained earnings accounts are configured before executing the first balance carryforward for a newly created company code.
