Administrators can change the priority of scheduled extract refreshes relative to other server tasks, 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 Change Priority, and enter a number between 1 and 100 to move the extract up or down in the priority list.
Select Delete to completely remove the schedule for the selected data sources.
