Hi,

I have a holiday table which has

Date                           Number

01/01/2016                1

02/01/2016                2

 etc and in my fact table I have 

TDD Date

Basically I am wanting a column/measure in my fact table that gets the number for todays date and minus the TDD Number.

Any help to go about this appreciated.

Thanks

Hi @Anonymous,

First what are today's number and the TDD number? What's the relationship between holiday table and fact table? And what's the logic to make today's number minus the TDD number?

Please share us more information about your requirement like your table structure and some sample data with its expected result.

Thanks,
Xi Jin.

Hi @Anonymous,

Did you mean this?

Measure:

Minus Value =
VAR TDDNum =
    CALCULATE (
        MAX ( Holiday[ID] ),
        FILTER ( Holiday, Holiday[Date] = MAX ( 'Fact'[TDD Date] ) )
    )
VAR TodayNum =
    CALCULATE ( MAX ( Holiday[ID] ), Holiday[Date] = TODAY () )
RETURN
    TDDNum - TodayNum

Thanks,
