How to resolve the error A function 'DATEADD' has been used in a True/False expression that is used

[PbiCeo]

Hello everyone,

I want to sum Amount with some conditions like below:
If a year month value is 2019 or 2020, it sums Amount of 1 year ago with 2 days plus.
(for example, 2020/1/1 -> value of 2019/1/3)
If a year month value is not 2019 or 2020, it sums Amount of of 1 year ago with 1 day minus.
However, got the error with the below measure.

measure :=
CALCULATE (
SUM ( 'Table'[Amount] ),
'Table'[Status] IN { "A" },
IF (
LEFT ( 'CALENDAR'[YEARMONTH], 4 ) IN { "2019", "2020" },
DATEADD ( DATEADD ( 'CALENDAR'[Date], -1, YEAR ), 2, DAY ),
DATEADD ( DATEADD ( 'CALENDAR'[Date], -1, YEAR ), 1, DAY )
)
)

Error:
A function 'DATEADD' has been used in a True/False expression that is used as a table filter expression.
This is not allowed.

How can I resolve that?

Encapsulate it in a FILTER() .

measure :=
CALCULATE (
SUM ( 'Table'[Amount] ),
'Table'[Status] IN { "A" },
FILTER(CALENDER,IF (
LEFT ( 'CALENDER'[YEARMONTH], 4 ) IN { "2019", "2020" },
DATEADD ( DATEADD ( 'CALENDER'[Date], -1, YEAR ), 2, DAY ),
DATEADD ( DATEADD ( 'CALENDER'[Date], -1, YEAR ), 1, DAY )
))
)

Btw, it's Calendar, not Calender. 🙂
