C_ABAPD Exam Questions: Free SAP System Tasks [2026]

Step-by-Step Execution:

1. Right-click your package in the Project Explorer, choose New, and select Data Definition.
2. Enter a name and description, select the database table as the Referenced Object, and choose Next.
3. Select the Define View Entity template from the list of templates and choose Finish.
4. Modify the element list to include specific fields, using the AS addition to define mixed-case alias names.
5. Define the key fields by placing the keyword KEY before the respective elements.
6. Press Ctrl + F3 to activate the data definition.
7. Place the cursor in the source code and press F8 to invoke the Data Preview tool.

Example Values:

• Name: Z00_R_EMPLOYEE
• Referenced Object: Z00EMPLOY
• Alias Names: EmployeeID, FirstName, LastName

Expected Result: An active CDS view entity that successfully fetches and previews data from the referenced database table using the newly assigned alias names.

Quick Mistakes:

• Including the client field in the CDS view element list when the source is a client-dependent database table, which should generally be excluded.
• Forgetting to define at least one key element in the view, which results in a syntax warning during activation.

Exam Insight:

• Tests knowledge of DDL syntax and the handling of client fields and primary keys in ABAP Core Data Services.
• Emphasizes the best practice of defining keys and using mixed-case aliases for improved readability in modern SAP programming models.

Step-by-Step Execution:

1. Right-click the active database table in the Project Explorer and choose Generate ABAP Repository Objects....
2. Select ABAP RESTful Application Programming Model -> OData UI Service and choose Next.
3. Ensure your target package is correct, then enter the required artifact names for the Data Model, Behavior, and Service components.
4. Complete the wizard, confirm your transport request, and choose Finish.
5. Open the newly generated Service Binding, press Ctrl + F3 to activate it if inactive, and choose Publish.
6. Select the entity from the Service Version Details section and choose Preview... to launch the Fiori app.

Example Values:

• CDS Entity Name: ZR_##Flight
• Binding Type: OData V4 - UI
• Service Binding Name: ZUI_##FLIGHT_O4

Expected Result: All required RAP development objects are generated, the local service endpoint is published, and a browser opens showing a functional Fiori application.

Quick Mistakes:

• Forgetting to choose Publish on the service binding before attempting to preview the app.
• Attempting to generate objects for a database table that does not contain the mandatory administrative fields for concurrency control (ETags).
• Clicking Next in the generator wizard before fully providing all required artifact names.

Exam Insight:

• Tests understanding of the RAP object generation wizard and the relationship between CDS entities, behaviors, and service bindings.
• Demonstrates how backend database models are exposed as consumable OData UI services for SAP Fiori.

Step-by-Step Execution:

1. Open transaction SQLM in the productive environment to activate the SQL Monitor for a specified period.
2. Allow the system to collect real-time database execution statistics across all ABAP objects.
3. Open transaction SQLMD to display the aggregated monitoring data.
4. Sort the analysis results by the total number of database executions or total database execution time.
5. Double-click the most expensive SQL statements to navigate directly to the unoptimized ABAP code line for refactoring.

Example Values:

• Transaction Code: SQLMD
• Sort Criteria: Total DB Time

Expected Result: A clear identification of the specific ABAP objects and exact lines of code that contain expensive or redundant SQL statements, allowing for targeted performance optimization for the SAP HANA database.

Quick Mistakes:

• Analyzing SQL performance in a sandbox development system with low data volume instead of a productive environment, leading to inaccurate execution metrics.
• Ignoring the volume of executions and only looking at individual query execution time, missing the impact of nested SELECT statements (SELECTs within loops).

Exam Insight:

• Tests the Optimize workstream of the custom code adaptation process.
• Validates knowledge of standard SAP performance tools used to refine and optimize legacy ABAP code for the SAP HANA in-memory architecture.

Resolution:

1. Locate the LOOP AT ... INTO statement in the source code editor.
2. Insert a MODIFY statement (without the INDEX addition) inside the loop before ENDLOOP.
3. Activate the class and execute the code to verify the internal table updates.

Prevention Tip: Remember that modifying a local work area does not alter the internal table memory; explicitly call MODIFY within the loop to save your changes.

Resolution:

1. Open the Problems view in Eclipse IDE, select the error message, and press Ctrl + 1
2. Choose the quick fix "Adjust and activate database table, convert data"
3. Once the Quick Assist log shows success, re-activate the domain definition

Prevention Tip: Always run a where-used list before shortening the length of a domain to understand which database tables will require a data conversion.
