  • Discussions are displayed using a Discussion widget.
  • A filter enables you to display all discussions or only those that the logged-in user is authorized to see.
  • A master-detail relationship between a Data Viewer widget and a Discussion widget linked to the data source will display only the discussions related to the current Service Manager object. Open url.png See the example.

Auto Refresh (Note: Only for dynamic data sources): Used to indicate the automatic refreshment interval for data from the data source in hours/minutes.

Caution: The updating of data requires additional activity on the Service Apps platform.

Best Practice icon.png  

  • You should define an automatic refreshment interval only if the app is required to constantly display real-time data for long periods of time on screen.

example  View dashboard data

  •  You should not specify an automatic refreshment interval if the app is only used for displaying a snapshot of data.

example  Display a portal where catalogs can be consulted



Master Datasource: In a master-detail relationship, this is the name of the master data source linked to the current data source.

Master Field: Name of the primary key in the master data source used to establish the link with the current data source.

  • As a general rule, it is the PK (Primary Key) column in the Service Manager) table.

Detail Field: Name of the EasyVista data source column identifying the key in the Service Manager table.

  • As a general rule, it is the column whose prefix is FK (Foreign Key).

example  You want to display all actions (detail data source) associated with an incident (master data source):

  • Master Datasource = Incidents data source defined using the Operation > Incidents > All Incidents parent query.
  • Master Field = PK identifying the Incident_ID column in the Incidents table.
  • Detail Field = FK_AM_ACTION_REQUEST_ID identifying the action number related to the incident.
