Counting a Measure
Hey PowerBI123456 ,
here you will find a new approach :-), be aware that this approach is referencing the columns from your dimension tables. For this it's also necessary to change the visuals as well. Meaning: use columns from the dimension tables instead.
This measure is also not that generic, as it returns the max requestID, so it will return the expected results whenever the acoount colum is used.
If you use the measure on a card visual it will retrun 12 instead of 4. If you need the 4 I recommend using a SUMX or COUNTX in combination with VALUES('...'[account]MaxReq Star = var t = ADDCOLUMNS( VALUES( 'DIM: Accounts'[Account] ) , "maxrequestid" , var MaxResponseID = CALCULATE( MAX( 'FACT: Activity'[ID] ) , ALL('DIM: Date' ) , ALL( 'DIM: Users' ) , ALL( 'FACT: Activity'[ID] ) , 'DIM: Activity'[Activity] = "Response" ) var MaxRequestID = CALCULATE( MAX( 'FACT: Activity'[ID] ) , ALL( 'DIM: Date' ) , ALL( 'DIM: Users' ) , 'DIM: Activity'[Activity] = "Request" --, 'FACT: Activity'[ID] = MaxResponseID - 1 , 'FACT: Activity'[ID] < MaxResponseID ) return MaxRequestID ) return CALCULATE( MAX( 'FACT: Activity'[ID] ) , TREATAS( t , 'DIM: Accounts'[Account] , 'FACT: Activity'[ID] ) )Here is a screen shot that shows the column usage of the tree map visual:
Be aware that the overall challenge we are facing is based on the fact that the datastore (our beloved SSAS Tabular inside Power BI) does not know a sequence data type. Sometimes, here, this makes things hard, the other times it's a plus.
Nevertheless, if this does not work, you might want to read this article, here I present a different approach to tackle the previous value challenge: The previous value - Mincing Data - Gain Insight from Data (minceddata.info)Regards,

TomMartens I have uploaded the PBI in the link below. The table on the left is what the data looks like and the table on the right is what the measure shows me. I want to do a count of that so it would be 4 in this example.
Hey PowerBI123456 ,
the most simple form to count if a measure returns a value, no matter of the result, is using the table iterator function COUNTX ().
The following measure iterates across the accounts, and counts the "Accounts" that return a value. As VALUES() returs a table (many rows, but just one column) with distinct values, no "double-counting" is happening.
Measure =
COUNTX(
VALUES(
'Activity'[Account]
)
, [Max Request ID]
)A little screenshot based on the pbix you provided:
Hopefully, this is what you are looking for,

TomMartens Thank you sooo much!
So another thing I am trying to do is a treemap showing the count by the user who made the last request, but this count is including all users who made a request on the account. Do you know how to only show the 4 users? Updated file: Sample File
Thank you so much for your help!
Hey PowerBI123456 , explain what should be counted based on your sample data in the pbix and the expected result.

TomMartens Hi - I am trying to show the users who put in the last request. Based on the data, it would be:
- Account 1: John
- Account 2: Will
- Account 3: Amber
- Account 4: John
I want to use a treemap to show that each of those 4 people had 1 request. The problem is my current treemap is counting everyone that made a request for each account, so its showing more than I want. Hope that makes sense.
