Dynamic property access?

[BenFransen]

I have created a measure like _thisDateCode = if(month(today())=1; "Jan"; if(.. up to dec

In my data I have columns from Jan, Feb, .. Dec.

I tried to make a calculation for the current month column like: This Months Total = sumx(filter('my_table'; 'my_table'[year]=year(today()); 'my_table'[_thisDateCode])

But that doesn't seem to work, I get an error:

Can I access a column dynamically using a measure? I got it working creating 11 if statements in the sumx' expression, but that feels clumsy. Besides I also need to make more measures with multiple criteria in the filter expression and would like to isolate repeating DAX parts to measures/variables.

Hi @BenFransen,

Based on my understanding, you want to make a calculation for current month, right? 

In your scenario, rather than using a measure to convert today's month number to month name, like Jan, Feb, Mar, etc, why don't you convert the text value in month column to numeric month number, like 1,2,3, etc.

You can create a calculated column called [MonthNo] in 'my_table' using below formula:

MonthNo=IF('my_table'[Month]="Jan",1,IF('my_table'[Month]="Feb",2,IF(...up to 12))

Then, the calculattion measure could be:
This Months Total = sumx(filter('my_table', 'my_table'[year]=year(today()), 'my_table'[MonthNo]=Month(Today())),'my_table'[ColumnName])

If I have something misunderstood, please elaborate your requirement with some sample data, and it would be better you can post an image to describe your expect output.

Best regards,

That's a possiblity as well, but it would be neater if it is/was possible to reference a column name dynamically. For now I'll stick with the current approach.
