Search for last date with certain condition

Hello, I'm Agustin lopez, Horticulture from Chile working with avocado. I'm working with some irrigation data set anda  I need a hand with a DAX.

I have 2 tables.
1- The theorical data table that is supouse what has to happend. (Name: Base de dato Agricola)
2- The data table with the data that really happend. (Name: Informacion Agricola)

I have the following data set

Table 1 (theorical irrigation)
Sector     Time of irrigation(min)
   5                 80
   6                100

Table 2 (Real Irrigation)
Sector      Date         Time of irrigation
 5           20-11-2021       80
 5            22-11-2021     160
 5             01-12-2021     80


In the dax, I need to see when was the last day (max date) of an irrigation that has a 2x time of irrigation from the Theorical data (Table 1). i.e. the dax should give me back the date of 22-11-2021  of the data set as example. I use as a key the Sector.

Thanks!

    Hi Alopez11 

    Try this:

     

     

    max date of an irrigation =
VAR _A =
    MAX( 'theorical irrigation'[Time of irrigation] )
VAR _B =
    FILTER(
        ADDCOLUMNS(
            'Real Irrigation',
            "TI", 'Real Irrigation'[Time of irrigation] / _A
        ),
        [TI] >= 2
    )
RETURN
    MAXX( _B, [Date] )

     

     

     

     

    I used this table as a Real Irrigation (Add some data for Sector 6):

     

     

     

     

     

    and the Output:

    Hi,

    This should do what you are describing:


    Irrigation Maxdate =
    var selection = SELECTEDVALUE('Irrigation T'[Irrigation])
    var sector = MAX(Irrigation[Sector]) return
    MAXX(filter(Irrigation,Irrigation[Irrigatio]=2*selection&&Irrigation[Sector]=sector),Irrigation[date])


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