Note: Ideally, for the Work Cache you should run an update rather than a refresh. To run a refresh in a site, you need to have Full Control permissions in the site.
Tip! You can easily run the Work Cache refresh from the Project Ribbon by clicking
Before running the Work Cache refresh you can check when the next scheduled run of the Work Cache update is set, and may decide it is worth waiting rather than performing a refresh.
To perform a refresh of either cache:
Click Site Settings.
Click Refresh BrightWork Caches.
Note: Depending on the size of the site and subsites the length of time this takes could vary.
