To ensure that customers are billed for only the services provided, the program manager wants the application to display a list of the services performed by the service provider. The list must include the following information:
- Name of the service performed
- Unit cost of the service
- Number of times the service was performed
- Total cost for each service
- Total cost of the services performed
On the Perform service flow, configure the CopySelectedServices data transform to copy services provided from a Service case to an Assistance request case.
The following diagram displays the relationships of the Selected services Embedded data type in the Assistance Request case type, and the Services data relationship in the Service case type to the Services offered data type.
The following table provides the credentials you need to complete the challenge:

Note: In a real-life implementation, ensure that the list of selected services in the Assistance Request case is read-only and restricts users from adding or removing items. You can remove the Add item and Delete controls by editing the section rule that displays the list, which is outside the scope of this challenge.
Note: The empty first row in the table is a result of the Selected services list initialization. You can remove the empty first row by deleting the .SelectedServices(1).pyLabel created by default in the pySetFieldDefaults data transform, which is outside the scope of this challenge.
