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: the name of the service performed, the unit cost of the service, the number of times the service was performed, the total cost for each service, and the 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 page list in the Assistance Request case type, and the Services page list in the Service case type to the Services offered data type.

3 Confirm your work

  1. In the header of Dev Studio, click Create > New > Assistance Request to create a new case.
  2. Advance the case to the Service stage.
    Note: In Enter customer information step, select a customer with standard coverage.
  3. On the Select service provider view, select a service provider.
  4. On the Select services view, enter the quantities provided in the following image.
  5. Verify that the total cost is $210.00. 
    Selected services USD210
  6. Click Submit to complete the Select services assignment and resolve the Service case. The Review service summary view is displayed.
  7. On the Review service summary view, verify that the Selected services table displays the three rows filled out in the Service case and that the value of the Invoice total field is $210.00.
    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.
    Review selected services USD210
Note: The empty first line in the list is a result of the Selected services list initialization. The empty line is added to the data relationship by the pySetFieldDefaults data transform in the AssistanceRequest class. To prevent the empty line from appearing in the list, open the data transform, and delete the line that sets the value of .SelectedServices(1).pyLabel.
