## Average on a column with 7 days moving window

Hi Dear Community,

I have a column which is a text column, containing 3 distinct values: Ok, Failed, Error.

I want to create a moving 7 days average either column or a measure of the Failed values.

I have this dax function:

Rolling 7 days AVG(column) =
CALCULATE (
COUNTA('alr ALR_PCI_SNIFFER_v2_DAILY_LOGS'[Result]), 'alr ALR_PCI_SNIFFER_v2_DAILY_LOGS'[Result] = "Failed",
DATESINPERIOD ('Date Table'[Date], LASTDATE ('Date Table'[Date]), -7, DAY),
)
Which gives only Blanks.

Can anybody help me figure this issue out?

Hi @Anonymous ,

You can try below formula:

``````Rolling =
CALCULATE (
COUNTA ( 'alr ALR_PCI_SNIFFER_v2_DAILY_LOGS'[Result] ),
'alr ALR_PCI_SNIFFER_v2_DAILY_LOGS'[Result] = "Failed"
&& DATESINPERIOD ( 'Date Table'[Date], LASTDATE ( 'Date Table'[Date] ), -7, DAY )
)``````

or

``````Rolling =
CALCULATE (
COUNTA ( 'alr ALR_PCI_SNIFFER_v2_DAILY_LOGS'[Result] ),
'alr ALR_PCI_SNIFFER_v2_DAILY_LOGS'[Result] = "Failed",
DATESINPERIOD ( 'Date Table'[Date], LASTDATE ( 'Date Table'[Date] ), -7, DAY )
)``````

@Anonymous , Check is Failed value has some spaces in table or have some issue with case

for Avg, you need a measure like

CALCULATE (
AverageX(values('Date Table'[Date]), CALCULATE (COUNTA('alr ALR_PCI_SNIFFER_v2_DAILY_LOGS'[Result]), 'alr ALR_PCI_SNIFFER_v2_DAILY_LOGS'[Result] = "Failed")),
DATESINPERIOD ('Date Table'[Date], MAx('Date Table'[Date]), -7, DAY),
)

It gives blanks even if I don't include that Result = "Failed" filter.
