Select the first value by date

Hello!

 

How can I via a measure get the oldest value by date in a table like this?

 

 

Tried FIRSTDATE, LASTEDATE and EARLIEST but it returns first 2021-01-01.

 

Kind Regards,

Anthon

    Hi, Anonymous 

    It is quite difficult for me to understand the cause of having the above result without seeing your data model.

    Please try to use MIN function in your measure.

    Or, please share your sample pbix file's link here, then I can try to look into it to come up with a more accurate measure.

    Hi Anonymous 

    The type of your column is Date/time, however, the type of argument that FIRSTDATE() accepts is Date.

    FYI:

    Besides, you can use the function MIN() mentioned by Jihwan_Kim.
