## every 8 days value

Indicator value =
var maxdate = MAX(data[Date])
var last6month = DATE(YEAR(maxdate), MONTH(maxdate) - 6, DAY(maxdate))
Return
IF(
LOOKUPVALUE('Date'[Last 8 days dates], 'Date'[Last 8 days dates], data[Date]) = data[Date] && MIN(data[Date]) > last6month,
data[IndicatorValue]
)
_____________________

Last 8 days dates =
var Firstdate_ =
CALCULATE(
MIN('Date'[Date]),
FILTER(
'Date',
'Date'[Date] = MIN(data[Date])
)
)

var lastdate_ =
CALCULATE(
MAX('Date'[Date]),
FILTER(
'Date',
'Date'[Date] = MAX(data[Date])
)
)

var Daterange = DATESBETWEEN('Date'[Date],Firstdate_,lastdate_)

var Series_ =
IF(
'Date'[Date] >= MIN(data[Date])
&& 'Date'[Date] <= MAX(data[Date]),
RANKX(
Daterange,
'Date'[Date],,
ASC
)*7
)

Return
IF(
'Date'[Date] >= MIN(data[Date])
&& 'Date'[Date] <= MAX(data[Date]),
MAX(data[Date]) - Series_
)

___________________

the calculated column and the measure will give me the every 8 days value in last 6 months,
the problem is the calculated coulmn would not work becuase i used DirectQuery mood. Rankx Can't be used here.

any solution?

Can you provide some sample data or simple pbix files? Sensitive information can be removed in advance. What kind of expected results do you expect? You can also show it with pictures.

Please provide sanitized sample data that fully covers your issue. If you paste the data into a table in your post or use one of the file services it will be easier to assist you. (I will be able to emulate Direct Query mode on my side)

Please show the expected outcome based on the sample data you provided. Screenshots of the expected outcome are ok.
