Acumulate fortnight

[Anonymous]

Hi, I´m new here and have a doubt about DAX.

Yesterday I was dealing with the purchase attachment and wanted to create a table with the following information:

Knowing that the supplier ship on the 15th and 1st of each month, I wanted a table that would accumulate those purchases on the days they ship, to get a table showing how much quantity I will receive on each day.

I tried to do a DAX measure with MTD and with this I was able to get the 15th day, but I am not able to get the 1st day.

Any suggestions?

Thanks.

Hi @Anonymous ,

Please follow the steps:

1.Create a new table

The model:

2.Create a table visual, and create a measure

Shipment =
VAR cur_date =
    MAX ( 'Table 4'[Dates] )
VAR pre_date =
    CALCULATE (
        MAX ( 'Table 4'[Dates] ),
        FILTER ( ALL ( 'Table 4' ), 'Table 4'[Dates] < cur_date )
    )
VAR temp_table =
    CALCULATETABLE (
        'Table 3',
        'Table 3'[Date] <= cur_date
            && 'Table 3'[Date] >= pre_date
    )
RETURN
    CALCULATE ( [sum_purchase], temp_table )

If I misunderstand your demands, please feel free to let me know.

@Anonymous Not 100% following, what are the expected results from the sample data?

Sorry @Greg_Deckler , I just see that the table is not okay.

My table´s purchase has the following structure:

Date		Purchase
2022/01/05		706
2022/01/10		1,312
2022/01/22		806
2022/01/27		210
2022/02/02		1,037
2022/02/10		1,808
2022/02/17		1,311
2022/02/25		1,793
2022/03/03		1,500

And I want to get the next table: 

Dates		Shipment
2022/01/15		2,018
2022/02/01		1,016
2022/02/15		2,845
2022/03/01		3,104
2022/03/15		1,500
