 Open url.png  See General remarks on data sources.

Best Practice big icon.pngBest practices

  • You should use an Easyista KPI data source when it is linked to a KPI widget containing chronological data.
  • The indicator is not recalculated when data from the data source is updated. Its calculation frequency is completely independent. As such, you should not specify an automatic refreshment interval for the data source (using the Auto Refresh property) that is less than the indicator calculation frequency.

Example

You want to view performance Product name - ev itsm.png indicators for the number of incidents created this week

  • Data source linked to the parent query of the indicator Number of incidents created this week (indicator calculated twice a day)
  • Display the data from the data source using a KPI widget

SelectFirstRowAsCurrentRecord

Select First Row As Current Record: Used to indicate if the first record of the data source, when displayed in widgets, is selected by default (box is checked) or if no record is selected by default (box is not checked).

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

AutoRefresh

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.

    Best Practice icon.png

  • 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.
