Szenario

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

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 Selected Services data type. This relationship has already been created and added to the Review service summary Step.
