i have a requirement to calculate difference between days based on number of days selected.
for ex: if i select a day (10/11/2016) then QV should calculate difference between 10/11/2016 and 09/11/2016,
if i select 2 days (10/11/2016 and 09/11/2016,) then the difference should be calulated between 10/11/2016,09/11/2016 and 07/11/2016 and 08/11/2016, similarly for week and month
Can this be acheived?
The expression that i am using now is calculating difference of last 7 days and the previous week. can this be reused to acheive what i wanted to mentioned above?
sum({$<TransactionDate={">=$(vFirstOfLast7)<=$(vmaxDate)"}>} TAPNUM)
-
sum({$<TransactionDate={">=$(vTwoWeeksAgo)<=$(vEightDaysAgo)"}>} TAPNUM)
