## DAX measure in table running out of memory

Hi,

I have some DAX measures that are used in a table, they are running out of memory. Is there a better way to do this? I want to display this data in a table. What I want to do is measure the number of days between the latest date in the slicer to the invoice date. I have this measure to do this:

``````DaysSinceInvoice =
VAR MaxDate =
CALCULATE(
MAX('Data DateDimension'[TheDate]),
ALLSELECTED('Data DateDimension'[Date]))
VAR Result = DATEDIFF(Min([InvoiceDate]), MaxDate, DAY)
RETURN CONVERT(Result, INTEGER)``````

Then I have three measures that uses the above measure.

``````0To30Days =
VAR Result = IF(Min('Data InvoiceFact'[Owing]) > 0 && [DaysSinceInvoice] >= 0 && [DaysSinceInvoice] <= 30, Min('Data InvoiceFact'[Owing], 0)
Return Result

30To60Days =
VAR Result = IF(Min('Data InvoiceFact'[Owing]) > 0 && [DaysSinceInvoice] >= 30 && [DaysSinceInvoice] <= 60, Min('Data InvoiceFact'[Owing], 0)
Return Result

60To90Days =
VAR Result = IF(Min('Data InvoiceFact'[Owing]) > 0 && [DaysSinceInvoice] >= 60 && [DaysSinceInvoice] <= 90, Min('Data InvoiceFact'[Owing], 0)
Return Result``````

This is displayed in a table. Is there a more efficient way to do this? I am using a measure because I want to base the calculation on the date slicer selection.

You can try storing the data in variables so that the calculations only have to be done once, e.g.

``````0To30Days =
VAR DaysSinceInvoice = [DaysSinceInvoice]
VAR DaysOwing =
MIN ( 'Data InvoiceFact'[Owing] )
VAR Result =
IF (
DaysOwing > 0
&& DaysSinceInvoice >= 0
&& DaysSinceInvoice <= 30,
DaysOwing,
0
)
RETURN
Result
``````
