Previous non-continuous date value
I have a table from where I want to get the value from the previous available date for the specific Country-Indicator. The previous available date can be a day, month or quarter before.
I am available to get the inmediate previous date for the specified "Country-Indicator Key", and this is the formula I need support with twiking.
Previous Date =
CALCULATE(
MAX(Indicators[Date]),
ALLEXCEPT(Indicators,Indicators[Country-Indicator]),
Indicators[Date]<EARLIER(Indicators[Date])
)
What I get from the above DAX is a column that shows the previous available date for the specified "Country-Indicator":
Currently I have a work arround that creates a "Previous Key" and then looks for this value on the table, thus bringing the previous value, this can be either calculated column by column or in a single column:
Previous Value (not Fancy) =
VAR
PreviousDate =
CALCULATE(
MAX(Indicators[Date]),
ALLEXCEPT(Indicators,Indicators[Country-Indicator]),
Indicators[Date]<EARLIER(Indicators[Date])
)
VAR
PreviousKey =
FORMAT(PreviousDate,"yyyy-mm-dd")
&"-"&
Indicators[Country-Indicator]
RETURN
LOOKUPVALUE(
Indicators[Value_Rev],
Indicators[key],
PreviousKey
)
As mentioned I am looking for a way of modifying the "Previous Date" formulato bring the previous value instead of the previous date. I am just looking for a more elegant solution which I am confident it exists.

If the below screenshot is your expected result , please try the below code, you don't need to combine the Country and Indicator as a key, don't need to add an index column in Power Query. Just use DAX code.PreviPreviousValue = VAR _CurrentDate = SELECTEDVALUE ( Sales[Date] ) VAR _PreviousDate = CALCULATE ( MAX ( 'Sales'[Date] ), ALLEXCEPT ( Sales, Sales[Country], Sales[Indicator] ), KEEPFILTERS ( 'Sales'[Date] < _CurrentDate ) ) VAR _Result = CALCULATE ( SUM ( Sales[Value_Rev] ), 'Sales'[Date] = _PreviousDate, REMOVEFILTERS ( Sales[Date] ) ) RETURN _ResultHi Oscar_Mtz_V
I think a good solution would be to create an Index column via Power QUery Editor mode (Add column pane -> Index column)
Then you will be able to do absolutely the same workaround as for date, but for Index column, like
Previous Value = CALCULATE( MAX(Indicators[IndexColumn]), ALLEXCEPT(Indicators,Indicators[Country-Indicator]), Indicators[IndexColumn]<EARLIER(Indicators[IndexColumn]) )do not hesitate to give a kudo to useful posts and mark solutions as solution
Why do I keep getting a earlier/earliest refers to earlier row contex that does not exist error?? Please help
I am trying to do this in Power Pivot.
