Use the tabcmd to do the same and run the below command
tabcmd refreshextracts --datasource sales_ds
go to workbook or datasource sections where datasource is present schedule the particular datasource alone so that under schedules tab you can see newly created scheduled task use that schedule to run a specific datasource refresh
Hope this helps kindly mark this answer as correct or helpful so that it will help others
Hi Naveen ,
is there any way other than tabcmd.
can refresh it from tableau server it self ?
i am trying to create new schedule task for that particular data source, no luck . it's automatically scheduling all extracts , i am not able to see any customization to select particular data source .
