## Getting the total value of a created Measure

#### This is the measure formula:

``````Meter 1 Consumption =
VAR ConsumptionToday =
CALCULATE(SUM(ConsumptionDaily[QC Meter 1]))
VAR ConsumptionPriorDay =
CALCULATE(SUM(ConsumptionDaily[QC Meter 1]), PREVIOUSDAY('ConsumptionDaily'[Date]))
VAR DIFF =
ConsumptionToday - ConsumptionPriorDay
RETURN
IF(ISBLANK(ConsumptionPriorDay),BLANK(),IF(DIFF<0,DIFF+9999999,DIFF))``````

### If you can help please

Helper I

You should use the effect of a telescopic sum here.
Instead of summing over all of the daily consumptions, just calculate the difference between first consumption and last consumption within the time, using your logic:

``````Meter 1 Consumption =
VAR MaxDate = MAXX(Datecolumn)
VAR MinDate = MINX(Datecolumn)
VAR ConsumptionEnd =
CALCULATE(SUM(ConsumptionDaily[QC Meter 1]), date = MaxDate)
VAR ConsumptionStart =
CALCULATE(SUM(ConsumptionDaily[QC Meter 1]), Datecolumn = MinDate)
VAR DIFF =
ConsumptionEnd - ConsumptionStart
RETURN
IF(ISBLANK(ConsumptionStart),BLANK(),IF(DIFF<0,DIFF+9999999,DIFF))``````

Might need to substract one day from MinDate.
