[happyfeet11]

Hi Friends

which means it has to be dynamic. 

how do i do it and please provide videos if anyone has them.

what you need are the boundary dates, pretty much the same principle as this post:

https://community.qlik.com/t5/New-to-Qlik-Sense/how-to-calculate-previous-year-sales-till-current-ye...

you change the expressions for the start and end periods you are interested in.

the only difference is that you want one condition ANDed with another condition to combine set analysis modifiers you use <>* <> which is an intersection

a little tweak:

use e function instead. 

the first measure are employees with vacations past 2 quarters,, 2nd are those in the future, third is for employees with future vacations but no vacation in the past 2 quarters.

note that all are controlled by start and end dates.  so with these expressions the challenge is really defining these boundaries. 

from the description above, its not very clear how to define the boundaries, so for proving the logic, these are the  variables (starting with vEndDate):

and it computes for the current quarter: vStartDate to vEndDate, 6 months back is v6MonthsPrior, and the future is day after vEndDate

the user selects any date, vEndDate gets the quarterend of the max of the selection.  from v6MonthsPrior to vEndDate is the 6-month period. vFuture is day after vEndDate
