New Release C_BASD_01 SAP Certified Development Associate Certification Questions

To run your application with live data, you need to do the following steps:

• In the target run configuration to run with, configure the data source as “Live Data”. This will enable your application to consume external OData services from their original sources, instead of using mock data from the sample data folder1.
• In the target run configuration to run with, configure the destination of OData service properly. For each OData service, you must specify the target configuration that refers to the external OData service: BTP destination name and an optional path to the service endpoint2.

You do not need to delete any existing run configurations that do not have “Live Data” chosen as data source, as they can be useful for testing your application with different scenarios. You also do not need to rename the target run configuration to run with, to make sure it contains “Run with Live Data” text, as the name of the run configuration does not affect its functionality.

To define associations, you must use data model entities. Associations are relationships between two entities that are defined in the data model layer of your application. You can use the CDS graphical modeler or the CDS source editor in SAP Business Application Studio to create and edit associations. Associations can be used to navigate from one entity to another, to filter or sort data, or to expose related data in a service model12

 To access the data in your application, you need to have the appropriate role collection assigned to your user. A role collection is a set of user-related authorizations that restrict access to resources and services based on defined user permissions. You can create a new role collection for your application in the SAP BTP subaccount cockpit, or use an existing one that matches your application’s requirements. Then, you need to assign the role collection to your user via the SAP BTP subaccount cockpit, so that you can access the data in your application. Redeploying the project or logging out and in again will not solve the issue, as the rolecollection assignment is independent of the deployment or the login process. References:

The correct way for an application developed on SAP Business Application Studio to use data directly from a back-end system is to consume an external data service. This can be done by using the Service Center in SAP Business Application Studio, which simplifies the connectivity to external data sources, enables data source exploration from different providers, and integrates the data source into the application in development. For example, you can consume an external service from SAP S/4HANA by adding the Business Partner API to your application and adding the Business Partner entity to your application service. References:
