Hi,
I have this Max function that's returning incorrect result. It's returning max date in data instead of date of the maximum count.
Example scenario: if selectedvalue [AIC_RTO] = "Ruapehu" then expected result = 01/01/2022. Manual check of max [Pop_Count] = 6051.
However current function is returning incorrect result of 31/01/2022
@tamerj1 , @Whitewater100 appreciate any help please. Thanks.
Max date of vistor count = IF( MAX(DataVentures_ALL[Pop_Count]) = CALCULATE(MAX(DataVentures_ALL[Pop_Count]) ,ALLSELECTED(DataVentures_ALL[AIC_RTO] ,DataVentures_ALL[Pop_Type])) ,
FORMAT(MAX(DataVentures_ALL[Date]) ,"dd mmm'yy" ))
Solved! Go to Solution.
Hi @Anonymous,
There some mistakes.
First, some filter you lost some filter on this visual. [Latsed month] is 0 applied on visual "Max daily visitor count", but not on "Max date of vistor count".
Then format the maximum date of 6051. You can just use 'DataVentures_ALL' table directly as the context due to it has been filtered by other slicers on this page. DAX you can refer this:
Max date of vistor count =
FORMAT (
CALCULATE (
MAX ( DataVentures_ALL[Date] ),
FILTER ( 'DataVentures_ALL', [Pop_Count] = MAX ( DataVentures_ALL[Pop_Count] ) )
),
"dd mmm'yy"
)
I modified your pbix file in the end you can refer.

@v-chenwuz-msft Perfect, that worked. Thank you so much for your response and help with this, much appreciated.

Here is the sample file with the solution https://www.dropbox.com/t/LfIreNwcUKqWWqSW
Actually I've noticed that even after modification, the measure still returns the very last date at the grand total level (Which is the level that is displayed at the card visual). Therefore I rewrote the measure as follows
Max date of vistor count =
Var SelectedTable =
CALCULATETABLE (
DataVentures_ALL,
ALLEXCEPT ( DataVentures_ALL, DataVentures_ALL[AIC_RTO], DataVentures_ALL[Pop_Type] )
)
VAR MAxCount =
MAXX ( SelectedTable, DataVentures_ALL[Pop_Count] )
VAR FilteredTable =
FILTER ( SelectedTable, DataVentures_ALL[Pop_Count] = MaxCount )
RETURN
FORMAT (
MAXX ( FilteredTable, DataVentures_ALL[Date] ),
"dd mmm'yy"
)
Also I notied that the card visual that desplays the maximum count is also returning wrong numbers at least as per my understanding (please let me know if I am mistaken). I wrote another measure for that:
MAx daily visitor count =
CALCULATE (
MAX ( DataVentures_ALL[Pop_Count] ),
ALLEXCEPT ( DataVentures_ALL, DataVentures_ALL[AIC_RTO], DataVentures_ALL[Pop_Type] )
)
This is how your dashboard looks like now
Hi @Anonymous
When you say "max [Pop_Count] = 6051.", this number is based on what exactly? What are you slicing by in your report?
@Anonymous
I failed to find a way to get "6051" as the maximum Pop_Count for AIC_RTO "Ruapehu" and Pop_Type "Domestic". I actually get "14766" applying manual filter. However, am not sure if I fully understand your requirement but I think the issue might be with ALLSELECTED which in my openion should be replaced with ALLEXCEPT
Max date of vistor count =
IF (
MAX ( DataVentures_ALL[Pop_Count] )
= CALCULATE (
MAX ( DataVentures_ALL[Pop_Count] ),
ALLEXCEPT ( DataVentures_ALL, DataVentures_ALL[AIC_RTO], DataVentures_ALL[Pop_Type] )
),
FORMAT ( MAX ( DataVentures_ALL[Date] ), "dd mmm'yy" )
)
Hi:
I'm better with having the data but will take a shot. Once your max measure is working the way you want, then
Can you try FIRSTNONBLANK OR LASTNONBLANK
Date of Max = LASTNONBLANK(DataVenture[Date], [put formula for the max here])) -Best Option
in a more simple example FIRSTNONBLANK(DataVenture[Date], SUM(DataVenture[units]))
If this doesn't work and you have example data I can check it out a bit later..Hope this helps.
Thanks for your quick response @Whitewater100 I tried your solutions but couldn't get it to work.
Here's link to sample file and I've highlighted the card visual referencing the max forumula.

Hello:
OK, final got it. Boy, yo have 20 dae tables (in the background) and some serious bi-di, however if you bring your filter over for month = 0 and use this measure it should be good to go. I beleive 7-11-20 is the all-time high but Jan1 2022 is what we get with the filtering with 6051 daily vistors.
The picture
Hello:
Can you give this a try?
@tamerj1 @Whitewater100 thank you both so much for your detailed responses, much appreciated. I haven't heard back from the client who owns the file/project. Yes I agree the data model is a bit complex and messy and requires some tweaking to make it more efficient.
I'll follow up again here if I hear back from the client to resume work on the project. Many thanks again for your help.
Good am:
When filtering down to your requirment on the DATAVENTURES_ALL I believe theresult was for 1-1-2022 with 651 count. I think that was solved?
If you can find a way to slide a date table in and get the facts and dims squared away, you should be in great shape!
Thanks!
Hi @Whitewater100 , agree the moded needs a date table and refinement but I'll leave that for the client to decide.
I did manage to resolve the issue based on current model by tweaking the formula based on the responses here including yours.
So again, many thanks for your kind efforts and help with this, much appreciated.
