Hi,
I am trying to figure out how to calculate the # of years a donor has been active.... if they have skipped a year, I want it to start over again.
i.e. in the table below, customer #2 should only be active for one year, because they did not donate in 2019. I can't figure how how to do this if they skipped a year or more.
Thanks!

Solved! Go to Solution.
Please try this measure expression in a table visual with your Fiscal Year column, replace Donors with your actual table name.
Consec Yrs =
VAR vMaxYear =
MAX ( Donors[Fiscal Year] )
VAR vThisCustomer =
MIN ( Donors[Customer ID] )
VAR vLatestNotDonation =
MAXX (
FILTER (
ALL ( Donors[Fiscal Year] ),
ISBLANK (
CALCULATE (
COUNTROWS ( Donors ),
Donors[Customer ID] = vThisCustomer
)
)
),
Donors[Fiscal Year]
)
VAR vLatestIfBlank =
IF (
ISBLANK ( vLatestNotDonation ),
MINX (
ALL ( Donors[Fiscal Year] ),
Donors[Fiscal Year]
) - 1,
vLatestNotDonation
)
RETURN
IF (
vMaxYear = 2020,
vMaxYear - vLatestIfBlank
)
