Manage Refresh Tasks
Administrators can manually refresh extracts or delete their schedules.
Sign in to the site that has the schedules you want to manage, and then click Tasks.
Select one or more scheduled extract refreshes.
From the Actions menu, do any of the following:
Select Change Schedule, and choose a new schedule from the list.
Select Run Now to refresh manually.
Note: If an extract does not have a scheduled refresh, you can refresh it on demand from the Data Connections page.
Select Delete to completely remove the schedule for the selected data sources.
