Calculate days

Hi all,

I would like to calculate the number of days each application is at each stage. 

 

 

From above image 'Earliest FirstDate' column shows the first date that the application went into each category. The categories listed above have subcategories, that's why there are more than one date for each category. I want to calculate the number of days between the first date of each category. You will seen a summary for Case ID showing first dates for each category.

 

 

For example I want to show:

'Post AIP- Pre App' days = ('Apps in Preparation' minus 'Post AIP- Pre App')

'Apps in Preparation' days = ('Apps With Credit' minus 'Apps in Preparation')

'Apps With Credit' days = ('Drawdowns - Apps With Credit')

'Drawdowns' = Total of all category days OR ('Drawdowns' minus 'Apps in Preparation')

 

Please note 'Sort Order' column is from a different tabel than the rest. See below.

 

Table  Column
Status Activity  Case ID
Status Activity  Stage
Stage Order  Sort Order
Status Activity  Status Date
Status Activity  Earliest FirstDate

 

Appreciate any help on this.

Thanks all.

      Hi Greg,

      Thanks for your reply.

      The sample data is in the first table above. There are a number of dates at each stage. I've created a measure that identifies the first date of each category. You will see the column called 'Earlies FirstDate'.

      I want to know how long the case has been at each stage using the first date of each stage.

       

      LineStageEarliest FirstDateDaysDays Calculation
      1Post AIP - Pre APP15/03/20230Line 2 minus 1
      2Apps in Preparation15/03/202319Line 3 minus 2

      4With CMO15/04/202319Line 5 minus 4
      5Drawdown04/05/202350Sum of line 1 to 4

       

      The table I'm using in Power BI is the first one with the columns:

      Case ID

      Stage

      Sort Order

      Status Date

      Earliest FirstDate

       

      Note also - Status source table is different to the others. I've included table view above.

      Hope you understand this.

      Thanks

        Hi  smithub , 

        I create a sample to have a test.

         

        Days Calculation = 
VAR _SUMMARZIE =
    SUMMARIZE (
        ALLSELECTED ( 'Table' ),
        'Table'[Case ID],
        'Table'[Stage],
        'Table'[Sort Order],
        'Table'[Earliest FirstDate]
    )
VAR _ADD1 =
    ADDCOLUMNS (
        _SUMMARZIE,
        "DateDiff",
            VAR _LINENEXT =
                MINX (
                    FILTER (
                        _SUMMARZIE,
                        [Case ID] = EARLIER ( [Case ID] )
                            && 'Table'[Sort Order] > EARLIER ( [Sort Order] )
                    ),
                    [Earliest FirstDate]
                )
            RETURN
                DATEDIFF ( [Earliest FirstDate], _LINENEXT, DAY )
    )
RETURN
    IF (
        MAX ( 'Table'[Sort Order] )
            = MAXX ( ALLEXCEPT ( 'Table', 'Table'[Case ID] ), 'Table'[Sort Order] ),
        SUMX ( _ADD1, [DateDiff] ),
        SUMX (
            FILTER (
                _ADD1,
                [Case ID] = MAX ( 'Table'[Case ID] )
                    && [Stage] = MAX ( 'Table'[Stage] )
            ),
            [DateDiff]
        )
    )

         

        Result is as below.

         

         

        Best Regards,
        Rico Zhou

    To solve this correctly in Power BI, create a new summary table with one row for each Customer_ID using this DAX formula:


    CustomerDays = SUMMARIZE(Tabla, Tabla[Customer_ID], "Dias", DATEDIFF(MIN(Tabla[Date_start]), MAX(Tabla[Date_end]), DAY))

    This will correctly calculate the days between the first and last date per customer. You can then do sums and averages on this new table (CustomerDays) in your visuals to get the correct values.
