To get the Connectivity Studio history data exported to the Dataverse database that is used by the Connectivity Monitor PowerApp, you need a special Connectivity Studio project: BisHistoryExport.
In the D365 F&SCM environment from which connectivity history must be exported, in Connectivity Studio, import the BisHistoryExport project XML file. For more information on how to import the project file, refer to Import project from file.
The BisHistoryExport project contains the predefined setup (messages, web service, connectors, and documents) that is required to export Connectivity Studio history data.
