HI nanutum ,
Can you please elaborate on why you are using LASTDATE function in your DAX?
You can use MAX function also.
Add details please: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490
Thanks,

The simple answer is: because LASTDATE returns a one-row-one-column table which can be used under CALCULATE as a filter. MAX is a scalar function and hence, it can't be used directly under CALCULATE.- Pragati11
Hi Anonymous ,
I am just trying to understand the requirement here.
Thanks,

nanutum , Create a date table join with this and use date from there.
To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

Appreciate your Kudos. - nanutum
As the error clearly says, LASTDATE is a table function that operates on a column of dates but the dates must be UNIQUE. This function should be used on a proper Date table in the model, not just on any column that happens to store dates.
Please create a proper calendar in your model, connect to your fact table and you'll be good to go.
By the way, your model should be a star schema. Please refer to this: https://docs.microsoft.com/en-us/power-bi/guidance/star-schema#star-schema-overview- nanutum
i very confused this 2 measure is not error in lastweek
Hi nanutum ,
Since there is no data sample and expected output , I’m not sure why the LASTDATE() function not works.
As this article said, 'firstdate' and 'lastdate' function not works if your date table contains duplicate records.
If you're using a fact table where the same date can be repeated more than once, you should use MIN and MAX instead.
If you have any further questions ,please upload your pbix file after doing mask sensitive data.
