Time buckets based on fiscal year

Dear Experts,

I am struggling to view data in dataview per fiscal period. I have tried creating fiscal year variant and assigned to time bucket profile but I still cant. Not sure what am I missing. Seems something very basic that is cost me a lot of time.

Could you share the steps needed to view the data in planning table by a period like Oct to September. 12 buckets = 1 period.

Thanks

Guru.
