How to calculate the measure only within one month?

[Anonymous]

Faced such a problem. There is a format table Key (unique) - Date - Doctor - Area

There is a measure that is calculated by the formula: Proc from total = count ('Reel status' [Key]) / CALCULATE (COUNT ('Reel status' [Key]), filter (all ('Reel status'), [Doctor] = "Doctor"))

I drop this measure to the visualization and add Area to the filters. As a result, I get the number of lines in which the Area corresponds to the one I need as a percentage of the total number of lines with Doctor in the "Doctor" field. And it works. I display information for the year and total rows with the Doctor status, I have 65K, and for a specific area - 28K. About 42% Will do.

But now I go down to the level below and see not completely correct statistics. The sum of all the columns is still 42%, but now they are smeared by months.

If I understood correctly, then in my measure the numerator is counted for a month, and the denominator is still common. How to explain the measure that if statistics are displayed for a month, then both count ('Reel status' [Key]) and denominator CALCULATE (COUNT ('Reel status' [Key]), filter (all ('Reel status'), [Doctor ] = "Doctor")) should be counted only for a month?

Hi, @Anonymous ;

I think you could create other measure .

Proc from month = COUNT(data[Key]) / CALCULATE (COUNT ([Key]), filter (ALL(data), MONTH([Spliced At])=MONTH(MAX([Spliced At]))&&[Doctor] = "Doctor"))

The final output is shown below:

@Anonymous , do have data for more than a year?

Demonimator is everything across all year for [Doctor] = "Doctor"

And numerator is based on axis

Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

Correctly it turned out to unload information in only a couple of months. Hope this will be enough.

No, now I have information only from the beginning of this year, but in the future I want to increase this range.
I will now try to make an upload without personal information.
