How to Omit part of time series for one department

Anonymous — Fri, 24 Jun 2022 14:48:10 GMT

We have a model where we have some outlier-values in a measure for one department until a given date. We want to keep the values in the model, but hide them from one of the visuals.

Basically I try to express a condition:

FilterTest = if(Sheet1[Department] = "New Haven" && Sheet1[Date] < 08/01/2021, 0, 'Key Measures'[SumXvalue])

... hoping that this will give me nothing for New Haven until August 2021 and the original value for all other departments, including for New Haven from August 2021 onwards.

I have tried various IF, SWICTH, CALCULATE and FILTER combos, but always end up with an error:

A single value for column 'Department' in table 'Sheet1' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.

The value we are working with in the real case is the result of a complex calculation (two 12-month rolling averages divided by eachother) so I cannot just omit the value from the underlying query.

I have uploaded a small pbix-file that illustrates the essence of the problem. Link to PBIX-file

Any suggestions would be highly appreciated.

I create a new table with a date giving the start date you want to show results for each department

Department	Date
Madrid	01/01/2018
Copenhagen	01/01/2018
New Haven	01/07/2021

and after i changed your measure

FilterTest =

var dategraph = min(Sheet1[Date])

var site= SELECTEDVALUE(Sheet1[Department])

var datemin=LOOKUPVALUE(Date_Afich[Date],Date_Afich[Department],site)

var result = if(dategraph>datemin,[SumXvalue])

return

result

Hope this will help you

Thank you very much! This worked and has now been implemented in the main model. Also served as an illustration on how we can share ideas and solutions in the forum. Great!
