    var _last a maxx(filter(Table, [FROM DATE] < earlier([FROM DATE])),[FROM DATE])
    Return
    if(isblank([expected]) to isblank(_last) , blank() , maxx(filter(Table, [FROM DATE] to _last),[Duration]) -[expected])

    Dear amitchandak ,

     

    The file last values.pbix run very well, but I don't know when I apply this for my project the error also show. My data is queried from SQL Server (Import data type).

     

    Maybe earlier cannot support this, right?

     

    Thanks.
