Measure to calculate based on previous data point.

 

Hello, I need to multiply to parameters. One of which is sampled every 3 days and I need to use the previse sampled point for today calculation until a new sample point arrive, (See screen clip). So for day 02/01/17 calculate 20*1000.

The calculation is:

Product of day parameters = calculate(PRODUCTX(Table2,Table2[PARA1]*Table2[Sample]),Table2[Day])

 

I thought that EARLIER should provide the answer but could not get is to work.

 

Thanks

Hi @Eyal

 

Following DAX formula will do the job

Product Of Day Parameters=
VAR PreviousSample =
    IF (
        ISBLANK ( Table1[Sample] ),
        CALCULATE (
            LASTNONBLANK ( Table1[Sample], Table1[Sample] ),
            FILTER ( Table1, Table1[Day] < EARLIER ( Table1[Day] ) )
        ),
        Table1[Sample]
    )
RETURN
    Table1[PARA2] * PreviousSample

Hi,

 

Try this

 

=calculate(PRODUCTX(Table2,Table2[PARA1]*IF(ISBLANK(Table2[Sample]),CALCULATE(SUM(Table2[Sample]),PREVIOUSDAY(Table2[Day])),Table2[Sample])),Table2[Day])

 

Hope this helps.
