I need to first group by my data by date and then calculate second quartile. I used the function SUMMARIZE() But I cannot refer the virtual table column as an argument in the PERCENTILE.INC() and gives below error
`
MyPercntile=
var tbl_group=SUMMARIZE(site,site[تاريخ],"summm",
CALCULATE(sum(site[حجم معامله به تن]))
)
var bb=PERCENTILE.INC(tbl_group[summm],0.2)
return
bb
error is Table variable 'tbl_group' cannot be used in current context because a base table is expected.
What should be done for functions that only have to pass columns?
