Solved: Need to find latest end date and earliest start da...

Anonymous · ‎02-21-2020

Project	st date1	end date 1	st date 2	end date 2
P1	2/2/2018	2/2/2020	4/4/2020	5/5/2022
P1	3/3/2019	3/3/2021	3/3/2018	6/6/2020
P2	1/1/2019	3/3/2022	1/3/2017	3/5/2020
P2	1/2/2018	4/4/2023	3/4/2018	5/1/2022

What I want output to be is

Project	st date 1	end date 1	start date 2	end date 2
P1	2/2/2018	3/3/2021	3/3/2018	5/5/2022
P2	1/2/2018	4/4/2023	1/3/2017	5/1/2022

Help will be greatly appreciated.

Thanks

Hi,

it depends a littel bit on what you want to do. Do you want to add a new table to the model? Or show the data in a table visual?

If you want to show it in a table you could just use 4 different measures:

Start 1 = MIN('ProjectTable'[st date1])
End 1 = MAX('ProjectTable'[end date 1])
Start 2 = MIN('ProjectTable'[st date2])
End 2 = MAX('ProjectTable'[end date 2])

If you want to get rid of the total row:

Start 1 = IF (HASONEVALUE('ProjectTable'[Project]), MIN('ProjectTable'[st date 1]))
End 1 = IF (HASONEVALUE('ProjectTable'[Project]), MAX('ProjectTable'[end date 1]))
Start 2 = IF (HASONEVALUE('ProjectTable'[Project]), MIN('ProjectTable'[st date2]))
End 2 = IF (HASONEVALUE('ProjectTable'[Project]), MAX('ProjectTable'[end date 2]))

To create a calculated table:

NewTable =
ADDCOLUMNS (
    VALUES ( ProjectTable[Project] ),
    "Start 1", CALCULATE ( MIN ( 'ProjectTable'[st date1] ) ),
    "End 1", CALCULATE ( MAX ( 'ProjectTable'[end date 1] ) ),
    "Start 2", CALCULATE ( MIN ( 'ProjectTable'[st date 2] ) ),
    "End 2", CALCULATE ( MAX ( 'ProjectTable'[end date 2] ) )
)

Hello @Anonymous , I have written 2 of the 4 DAX Measures required here. You can easily substitute Start Date 1 and End Date 1 with Start Date 2 and End Date 2 in the formula. See formulas below:

Earliest Start Date 1 =
CALCULATE (
    MINX (
        SUMMARIZE (
            'Table',
            'Table'[Project],
            "minimumdate", MIN ( 'Table'[st date1] )
        ),
        [minimumdate]
    )
)
Latest End Date 1 =
CALCULATE (
    MAXX (
        SUMMARIZE (
            'Table',
            'Table'[Project],
            "maximumdate", MAX ( 'Table'[end date 1] )
        ),
        [maximumdate]
    )
)

Hi, there is just one small thing I am not able to format it on the date, its not giving any option to change, would you be able to help?

Anonymous · ‎02-21-2020

In a table/calculated table in Power BI you can change the display format here if that's what you mean. The same for measures.

Hope it helps 🙂

Hi Thanks for your suggestions, I did apply those formulas but somehow its not bringing in the right values.

For some its picking up correctly but for most its just picking a random dates from the column.

Anonymous · ‎02-21-2020

Hi @Anonymous,

I tried my formulas on your example data and it gave the same result as what you wanted.

Thanks . Thats strange it does not for me.

How are you using the measures? In a table? Pivot table? Did you try the calculated table?

NewTable =
ADDCOLUMNS (
    VALUES ( ProjectTable[Project] ),
    "Start 1", CALCULATE ( MIN ( 'ProjectTable'[st date1] ) ),
    "End 1", CALCULATE ( MAX ( 'ProjectTable'[end date 1] ) ),
    "Start 2", CALCULATE ( MIN ( 'ProjectTable'[st date 2] ) ),
    "End 2", CALCULATE ( MAX ( 'ProjectTable'[end date 2] ) )
)

Yes, I did , with same results unfortunately.

@Anonymous Please share the formulas you have written for a check.

@Anonymous this looks very correct to me. Have you checked that you don't have some other report filters hindering this? Do you mind a call via Zoom and you share your screen?

Anonymous · ‎02-21-2020

I dont mind at all , I dont ahve an account on zoom though.
