Fiscal weeks (Time Buckets Profile - Data View)

I can upload the data in calendar days and display data in periods (which are fiscal months) in my data view .

But I cannot display data in fiscal weeks. I can display data in calendar weeks only.

I cannot see any option for Fiscal Weeks in Display and Basic periodicity in /SAPAPO/TR30 ( Time Buckets profile transaction)

Is there any settings in time buckets profile to display in fiscal weeks.

I have weeks, months, posting period checked in Storage Buckets Profile (/SAPAPO/TR32) and also I entered Fiscal year variant .

Any input will be highly appreciated .
