How to reference the last value a measure produces, within that measure?

[Jmaguirre7]

I have measure that is a running total across a calendar table.  It adds known future inventory injections and subtracts estimated sales for each day.

I would like it to check if the value of the previous date was less than zero.  That way I can modify the measure to stop subtracting the estimated daily sales until another positive inventory injection is received.

Or maybe there is a better way, I have attached a picture of the table for reference.

Hey @Jmaguirre7 ,

did it work with the measure I proposed?

I'm curious if you could solve this issue 🙂

Hello @Jmaguirre7 ,

sure, save the MAX date in a variable and subtract one day.

Then in the Calculate statement use your measure and overwrite the date with yesterday's date. If it's smaller than 0 give another result, otherwise your measure:

Running Total yesterday =
VAR vPrevDay = MAX( 'DateTable'[Date] ) - 1
VAR vRunningTotalYesterday =
    CALCULATE(
        [Running Total],
        'Date'[Date] = vPrevDay
    )
RETURN
    IF(
        vRunningTotalYesterday < 0,
        BLANK(),
        [Running Total]
    )

If you need any help please let me know.
