percentile, group by multiple categories

[rathinavelr]

HI, I need some help from you experts. I tried researching as many articles online but could not find something that would solve my problem. 

I have a table that has data that looks like the one below. I need to see the 80th Percentile Lead time by quarter and/or by site dynamically in a visual. I did look into the percentile visual but could not get it to work the way i require it to work. The Materials are unique to a site, so that is not a concern. 

I would have to see 80th Percentile Lead time by site, 80th percentile lead time by quarter and then see 80th percentile lead time by quarter and site together. I have about 3000 such datapoints to work with. 

HELP ! 

Site	Quarter	Material	Lead Time
Italy	2016Q1	POL1	125
Italy	2016Q1	POL2	110
Malaysia	2016Q1	POL3	90
Malaysia	2016Q1	POL4	87
Japan	2016Q1	EPI1	110
Japan	2016Q1	EPI2	98
Italy	2016Q2	POL5	115
Italy	2016Q2	POL6	100
Malaysia	2016Q2	POL7	80
