## LAST DATE

Hello,

I have a What-if parameter set to increment every 7 days.

For example, selected is LAST 7 DAYS from today’s date (August 21-27).

Goal: If a product does not have any sales within this selected parameter, the value should be = zero (0).

Problem: However, a “last 7-day period” value still shows up based on the “LAST” sale.  If the last sale was a far back in March, the value shows the last-7 day sales in March.

Is there something missing in the formula below?  Is it a problem with the DATESINPERIOD and LASTDATE?

Thanks.

---------------------------------

Parameter = GENERATESERIES(7, 365, 7)

Parameter Value = SELECTEDVALUE('Parameter'[Parameter], 7)

----------------------------------------

RollingSum =

VAR NumDays = Parameter[Parameter Value]

VAR RollingSum =

CALCULATE(

SUM('SALES_TABLE'[Invoiced QTY]),

DATESINPERIOD('SALES_TABLE'[Postingdate], LASTDATE ('SALES_TABLE'[Postingdate]),-Parameter[Parameter Value],DAY)

)

RETURN

RollingSum

@Oros usually for time intelligence you should use a calendar table, and you can easily create one from my blog post here Create a basic Date table in your data model for Time Intelligence calculations | PeryTUS IT Solutio...

but you can change your measure like this and try

``````RollingSum =

VAR NumDays = Parameter[Parameter Value]

VAR RollingSum =

CALCULATE(

SUM('SALES_TABLE'[Invoiced QTY]),

DATESINPERIOD('SALES_TABLE'[Postingdate], TODAY(),-Parameter[Parameter Value],DAY)

)

RETURN

RollingSum``````

Hi @parry2k ,

Unfortunately it is still showing the very old 'last 7-day' sales instead of the absolute last 7-day sales from today.
