EasyVista Discussions Data Source
This data source belongs to the Applications category in the data source library. It is used to define a dynamic data source associated with Service Manager discussions.
- 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.
See the example.
Notes
See General remarks on data sources.
- Discussions related to the current object are displayed by specifying the master-detail relationship, i.e. the relationship between the Data Viewer widget and the Discussion widget linked to the data source. See the procedure.
