D365fO Management Reporter reset data mart

If you need to reset the data mart of the managemnt reporter in D365fO the easiest way is to log onto the box that is running the management reporter service. For example BI Server for SAT environments.
Open a PowerShell as an administrator and run the following command:

J:
cd J:\MRProcessService\MRInstallDirectory\Server\MRDeploy
Import-Module .\MRDeploy.psd1
Reset-DatamartIntegration -Reason OTHER -ReasonDetail "TESTDBrestore"


valid values for -Reason are: SERVICING, BADDATA, OTHER.
-ReasonDetail parameter is free text
both are not important. They are just stored in the environment monitoring.
