Hello Experts,
I have a report table with :
- Multiple Report periods with same values (one by reseller active contract over period): 01/01/2021,01/12/2021,01/11/2021 ....
- Those resellers can have multiple contracts with the same reference for the same period.
I must retrieve the distinct lost contracts from previous periods ( month -1, month -2 ...)
I have tried comparing two results with except but i don't know why this is not working as it doesn't return correcly my reseller ref.
Attrition M =
var _Q = SELECTEDVALUE(Revenue[Period])
var _Q_1 = DATEADD(Revenue[Period],-1,MONTH)
var _Resellers = CALCULATETABLE(DISTINCT(Revenue[Reseller Ref]),
FILTER (ALL(Revenue[Period]),
Revenue[Period] = _Q))
var _Old_resellers = CALCULATETABLE(DISTINCT(Revenue[Reseller Ref]),
FILTER (ALL(Revenue[Period]),
Revenue[Period] = _Q_1))
RETURN
COUNTROWS(
EXCEPT(_Old_resellers,_Resellers)
)
I give you a sample with my queries in attachment:

Regards.
Thank you for your reply @amitchandak I am really lost !
In fact it seems the same problem than my other request:
MTD =
var _Q = SELECTEDVALUE(Revenue[Period])
var _Resellers = CALCULATETABLE(DISTINCT(Revenue[Reseller Ref]),
FILTER (ALL(Revenue[Period]),
Revenue[Period] = _Q))
RETURN
COUNTROWS(_Resellers)
LMTD =
var _Q_1 = DATEADD(Revenue[Period],-1,MONTH)
var _Old_resellers = CALCULATETABLE(DISTINCT(Revenue[Reseller Ref]),
FILTER (ALL(Revenue[Period]),
Revenue[Period] = _Q_1))
RETURN
COUNTROWS(_Old_resellers)
Lost MTD = SUMX(VALUES(Revenue[Reseller Ref]),if(ISBLANK([MTD]) && not(ISBLANK([LMTD])) , 1,BLANK()))
New MTD = SUMX(VALUES(Revenue[Reseller Ref]),if(ISBLANK([LMTD]) && not(ISBLANK([MTD])) , 1,BLANK()))
I retrieve 0 values for LOST MTD. It seems related to SELECTEDVALUE segment:
Which retrieve multiple values from my report:
@Anonymous , refer if this approach of using isblank can help
