SAP ABAP CDS Basic Exercises
1. Create a new CDS view and define the data structure by using the ABAP Core Data Services (CDS) syntax.
2. Implement the SELECT statement in the CDS view and retrieve data from the underlying database tables.
3. Use CDS associations to define relationships between different CDS views.
4. Implement CDS expressions and calculated fields in the CDS view to perform complex calculations on the data.
5. Use CDS annotations to add additional metadata to the CDS view such as labels and descriptions.
6. Implement CDS associations with cardinality and use the ON-condition to define the association behavior.
7. Create CDS views with input parameters and use them in the SELECT statement to retrieve data based on user input.
8. Use CDS views to define the data model for an OData service and expose the CDS views as entities in the OData service.
9. Use CDS views as the data source for a new ABAP report and display the data in a tabular format.
10. Use CDS views in a new ABAP class to perform business logic and use the data from the CDS view.
SAP ABAP CDS Advance Exercises
1. Create a CDS view that utilizes the CDS Join construct to join multiple tables and retrieve data from them.
2. Implement the use of CDS views with type hierarchies, which allow to create a parent-child relationship between different entities.
3. Use CDS views to implement the Unions and Intersection concepts to combine data from different views.
4. Use CDS views to implement complex filtering and sorting logic, using the CDS Where and Order By constructs.
5. Implement the use of CDS views with the Association Path construct to navigate through the associations defined in the CDS views.
6. Use CDS views to implement the use of Aggregates and Group By concepts to perform calculations on the data.
7. Implement the use of CDS views with the SELECT statement using sub-queries and subselects.
8. Use CDS views to implement the use of CDS views as function modules and pass input parameters to the CDS views.
9. Implement the use of CDS views with the SELECT statement using UNION, INTERSECT and EXCEPT.
10. Use CDS views to implement the use of the CDS views with the SELECT statement using the CASE construct and perform conditional calculations on the data.
