List of properties


Alias/Connector: EasyVista Service Manager connector used by the data source.

Filter: Filter used to restrict data from the data source.

  • All Discussions: Used to display discussions visible on the Home page > All Discussions tab in Product name - ev itsm.png. These are all of the discussions that logged-in users are authorized to see based on their domain and the visibility of the discussion.
  • My Discussions: Used to display discussions that logged-in users can see on the Home page > My Discussions tab in Product name - ev itsm.png. These are as follows:
    • Discussions they authored.
    • Discussions to which they contributed.
    • Discussions to which they were invited by the author.
    • Discussions they follow.

Configure Field Types: Used to display a preview of the structure and data from the data source via a data editor. 

  • The button Apps - datasources Properties - Preview button.png displayed below the property indicates the number of extracted rows (up to a limit of 15) and columns. Click on it to open the editor. Open url.png See the Description.
  • The button will display No data available as long as you have not selected any of the mandatory elements of the data source.
  • In edit mode, only the first 15 data source records are displayed.
  • In execute mode, all of the data source records are displayed.
  • Data in static data sources comes from the last file upload.
  • Data in dynamic data sources is updated when you open the app in edit mode.

No Data Message: Message displayed when no data is returned in the data source. Enter the code directly in the field or click Apps - Edit Html icon.png to open the text editor


Auto Refresh (Note: Only for dynamic data sources): Used to indicate the automatic refreshment interval for a dynamic data source. The frequency is expressed in hours/minutes. The updating of data is done in execute mode or edit mode, each time the app is run and each time the page is redisplayed.

  • Because the updating of data requires additional activity on the EasyVista Service Apps platform, 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 a screen.

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

Master Data Source: 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 Product name - ev itsm.png table.

Detail Field: Name of the EasyVista data source column identifying the key in the Product name - ev itsm.png table. As a general rule, it is the column whose prefix is FK (Foreign Key).

Example documentation icon EN.png You want to display all actions (detail data source) associated with an incident (master data source):

  • Master Data Source = 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.
