7 Day Rolling - Issues with date slicer

[Anonymous]

Hello,

I am trying to put togther a 7 day rolling average and the formula works, but when I use the slicer to select the amount of days I want to see (28, 42, 63) the first couple of days are not calculating the previous vaules it just starts to calculate from the begining of the period selected. I want those intial values to stay stable, continue the pattern, and not recalculate. Below the formula I am using.

► 7 day cancelled meetins =

averageX(

DATESINPERIOD(

'Team Schedules'[Scheduled_Department_Date],

LASTDATE('Team Schedules'[Scheduled_Department_Date]),

-7,

DAY),

CALCULATE([Cancelled Meetings]))

Hi,

You should have a Calendar Table with a relationship from the Scheduled_Department_Date of the Team Schedules table to the Date column of the Calendar Table.  Create a Date slicer from the Calendar Table and select a certain date in that slicer.  Now try this measure

7 day cancelled meetins = averageX(DATESINPERIOD('Calendar'[Date],min('Calendar'[Date]),-7,DAY),[Cancelled Meetings])

Hope this helps.
