Kindly follow below steps.
First right click on client name as shown below. then click on sort.
By clicking sort, it will open another window as shown below. then click sort order as descending,
and sort by field and select your measure and aggregation, it will sort based on your selection.
With out fiscal I am able to sort properly. But with fiscal year we are unable to do .
We have to sort all measures simultaneously depending on client.
Our business Req is if I sort 1 measure either in ascending or descending the entire table should be sorted accordingly
It won't possible. If we sort one measure then entire table will change based on that measure, but it does not sort all measure at a time. Tableau does not provide entire table sorting option. you can sort only one dimension or measure and based on this entire table changes.
