Issue
When accessing the Dashboards in Patch and Compliance and check the "Patch Installed" dashboard, it shows no data at all, even though you have recently run a repair task which had successfully installed patches to the client machines.
Cause
The historical information gathered only included definitions published less than 90 days ago by default, any previously released definition will not be reported on.
Solution / Workaround
1. Go to Patch and Compliance > Create a task > Gather historical information.
2. Set the value of the "Build report data for definitions published less than" to a longer period than the release date of the patch you wanted to report on.
E.g. The patch I have installed with Patch Manager was released on 2016/7/12, thus I have set this value to "250" days. ( Today's date is 2017/2/6)
3. Select "Save and gather now", wait for the job to finish.
4. Now data has been imported and is shown on the dashboard.
