Days Beetween deliverydates

[RWWRRW]

I have a table with different order numbers, different materials and different delivery dates.
I would now like to have the number of days of the delivery date per material evaluated. In Excel I had the function Days.
In Power Bi this does not work with Datediff.

How i can solve it via a DAX Formula? A Measure oer a calculated Column?

Please provide more information/sample data. It will matter the days  to compare are in separate tables, different rows, etc.

sorry i hope this table shows it. I want in Power Bi via Dax calculate the days beetween the deliverdates from each part

PO	Part	Date LfD	days
551196	4711	07.06.2023
551197	4711	19.06.2023	12
82706078	4712	23.06.2023
82693981	4712	30.06.2023	7
5555125	4713	07.06.2023
5555126	4713	22.06.2023	15
6238279	4715	29.06.2023
6238447	4715	29.06.2023	0
6240493	5050	16.06.2023
6238006	5050	24.06.2023	8
552230	5053	01.06.2023
552230	5053	15.06.2023	14
552230	5053	29.06.2023	14
6240497	78902	20.06.2023
6240576	78902	20.06.2023	0
6240915	78902	27.06.2023	7

Hi @RWWRRW

You can use RANKX to rank the dates by part and another calc column to get the previous date

DateRank = 
RANKX (
    FILTER ( 'Table', 'Table'[Part] = EARLIER ( 'Table'[Part] ) ),
    'Table'[Date LfD],
    ,
    ASC,
    DENSE
)

PrevDate (RANKX) = 
CALCULATE (
    MAX ( 'Table'[Date LfD] ),
    FILTER (
        FILTER ( 'Table', 'Table'[Part] = EARLIER ( 'Table'[Part] ) ),
        'Table'[DateRank]
            = EARLIER ( 'Table'[DateRank] ) - 1
    )
)

Or a single calc column to for the previous date

PrevDate (not RANKX) = 
CALCULATE (
    MAX ( 'Table'[Date LfD] ),
    FILTER (
        ALLEXCEPT ( 'Table', 'Table'[Part] ),
        'Table'[PrevDate (RANKX)] < EARLIER ( 'Table'[PrevDate (RANKX)] )
    )
)

For larger tables, I prefer the RANKX version. Performance shouldn't be an issue with small tables.

Now to get the difference, you can use either of the two previous date column

Difference = 
IF ( 'Table'[PrevDate (RANKX)] = BLANK (), 0, 'Table'[Date LfD] - 'Table'[PrevDate (RANKX)] )

You should have explained it better. Any ways here is the solution.

Use this measure to get days.

Duration = 
Var Start_Date = CALCULATE(MIN('Table'[Date LfD]),ALLEXCEPT('Table','Table'[Part]))
Var End_Date = CALCULATE(MAX('Table'[Date LfD]),ALLEXCEPT('Table','Table'[Part]))
Var Result = DATEDIFF(Start_Date,End_Date,DAY)
Return
Result

Output looks like this:

Not quite yet. It now correctly displays the daydiffernz from the first to the last delivery date. But the days between several delivery dates unfortunately not.
See marked in green.
For Part 5053 I expected from June 1 to June 15 (first delivery date to next delivery date)14 days difference from June 14 to June 29 (next delivery date to next) the difference of 14 days.
In the next part I have three delivery dates, here I would have expected as result 0 and in the second the 7 days day difference.
There can also be several delivery dates per part

Hello @RWWRRW you can use NETWORKDAYS DAX and create a measure and dont forget to mention ALLEXCEPT for the material column so that it will pick days for each material individually.

Your measure should look like this:

Duration = Calculate(Networkdays(Start_Date,End_Date),ALLEXCEPT(Table_Name, 'Table_Name'[Material_Column]))

This will give you the duration for each material individually.
