Applying MAX to Summerize

AltGr9 — Thu, 11 Nov 2021 11:31:35 GMT

Hello all, I have a summerize statement that returns a count of rows by date, and I'm trying to find the max date with a count greater than 10.

Here is what I have so far, but it doesn't want to accept _s[Count]. Any help would be appreciated.

Max Date With Count Greater Than 10 = VAR _s = SUMMARIZE ( 'Fact Table' ,'Fact Table'[Date] ,"Count", COUNT('Fact Table'[Date]) ) RETURN CALCULATE( MAXX(_s, [Date]), _s[Count] > 10 )

Hi,

I am not sure how the measure operates without seeing the actual sample file. However, what I can suggest based on what I see is that, inside VAR in your measure, you can try to filter _s table first, and then write RETURN MAXX(.....

If you can share your sample pbix file's link, it will be helpful.

Thank you.

Hi Thanks for your help.

Is this the link you asked for? It says "People in your organization" so I don't know if you'll have access.

Hi,

Sorry that if I was not clear.

I was asking for the sample power bi desktop file's link, not your power bi service link.

Thank you.

One final thing: I would like it to be dynamic, so not using a calculated table.

Hi,

Please check the below picture.

One thing that I want to share is, try to use addcolumns & summarize functions together, instead of using only summarize when adding expressions to the virtual summarized table.

The reason is that, not very often happen in general cases, but in some cases (in fact, quite a lot...), if authors use only summarize function and add expressions into the virtual summarized table, there might be an issue in creating correct numbers and having a good performance.

Max Date With Count Greater Than 10 =

VAR _s =

FILTER (

ADDCOLUMNS (

SUMMARIZE ( 'Fact Table', 'Fact Table'[Date] ),

"Count", CALCULATE ( COUNT ( 'Fact Table'[Date] ) )

[Count] > 10

)

RETURN

MAXX ( _s, 'Fact Table'[Date] )
