value for min/max date for each item in table

[kageyoshi777]

I'm trying to show the difference between lowest/highest value of real estate offers next to eachother in one table.

I've got table like this.

advert_number	data_download	price
111	02.01.2020	100
111	03.01.2020	200
111	04.01.2020	300
…	…	…

And measures..

Mindate = 
CALCULATE(MAX(estate_data[price]), FIRSTDATE(estate_data[date_download]))

Maxdate = 
CALCULATE ( max ( estate_data[price] ), LASTDATE(estate_data[date_download]))

But for some reason in few cases I dont see price for min/max date like in this example. 

Where I made an error?

Hi,

For these kind of calculations I recommend using thins kind of pattern:

Maxdate = 
var _mdate = CALCULATE ( max (estate_data[date_download]),All(estate_data[advert_number]))return

CALCULATE ( max ( estate_data[price] ), all(estate_data[date_download]),estate_data[date_download]=_mdate)

The idea here is to first define the desired date in variable then remove some filter context using all and finally returnin filters to the calculation by using the variable defined. You might need to adjust the variable and ALL to get the desired outcome but the idea remains the same. If you have calendar table instead of using ALL(estate_data[date_download]) in the calculate you can use ALL(calendar).

I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!

Hi, this solution does not solve my problem 😑. Of course for some "adverts" it works, like old measures worked too.

But for others still nothing. 

In this case I'm not using any data tables etc. Only plain data table like in my first post

Hi  @kageyoshi777 ,

I created a sample pbix file(see attachment) for you, please check whether that is what you want. You can update the formula of measure [Mindate] and [Maxdate] as below:

Mindate = 
VAR _seladvert =
    SELECTEDVALUE ( 'estate_data'[advert_number] )
VAR _mindate =
    CALCULATE (
        MIN ( 'estate_data'[data_download] ),
        FILTER (
            ALLSELECTED ( 'estate_data' ),
            'estate_data'[advert_number] = _seladvert
        )
    )
RETURN
    CALCULATE (
        MAX ( 'estate_data'[price] ),
        FILTER (
            ALLSELECTED ( 'estate_data' ),
            'estate_data'[advert_number] = _seladvert
                && 'estate_data'[data_download] = _mindate
        )
    )

Maxdate = 
VAR _seladvert =
    SELECTEDVALUE ( 'estate_data'[advert_number] )
VAR _maxdate =
    CALCULATE (
        MAX ( 'estate_data'[data_download] ),
        FILTER (
            ALLSELECTED ( 'estate_data' ),
            'estate_data'[advert_number] = _seladvert
        )
    )
RETURN
    CALCULATE (
        MAX ( 'estate_data'[price] ),
        FILTER (
            ALLSELECTED ( 'estate_data' ),
            'estate_data'[advert_number] = _seladvert
                && 'estate_data'[data_download] = _maxdate
        )
    )

If the above one can't help you get the desired result, please provide more sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
