SSRS表达式计数查询

Question

I have table where want to display a count of all cases opened in last 30, 90, 180 and 12 months.

I have following expressions which errors when I run my report. I specified the team name and count is on Involvement ID.

Any ideas.

This is my expression:

=CountDistinct(iif(Fields!Team.Value="AAC",(IIF(DateDiff("d", Fields!OPEN_DATE.Value, Now) <= 30,Fields!INVOLVEMENT_ID.Value,Nothing))))

Answer 1

Your first IIf function doesn't have a third argument:

=CountDistinct(iif(Fields!Team.Value="AAC",(
IIF(DateDiff("d", Fields!OPEN_DATE.Value, Now) <= 30, Fields!INVOLVEMENT_ID.Value, Nothing)
), ...))
