İ need your helps one more time to create a formula about below situation .

 

İ have two tables as below  .

 

Table 1 : contains product , request delivery date, and requested quantities .

Table 2 : contains the stock quantities of the products.

 

 

 

 

 

 

 

As you see i have different delivery dates with different quantities.İ just want to distrubute the stock quantities based on delivery dates..İ would like to show you to  step by step ( based on only one product ) .İ want to tell like that because the issue has some interesting details so just i want to tell correctly 

 

For Product PRC1 distribution: 

 

 

 

 

 

For Product PRC2 distribution: 

 

 

 

 

and the finally whole new table 1 will be as below :

    HI erhang

     

    Try this MEASURE

     

    Distributed Stocks =
VAR stock_to_distirubute =
    CALCULATE (
        SUM ( Table2[Stock Qty] ),
        CROSSFILTER ( Table2[Product], Table1[Product], BOTH )
    )
VAR Cumulativestock =
    CALCULATE (
        SUM ( Table1[Requested Qty] ),
        FILTER (
            ALLEXCEPT ( Table1, Table1[Product] ),
            Table1[Rquested Delivery Date]
                <= SELECTEDVALUE ( Table1[Rquested Delivery Date] )
        )
    )
VAR myqty =
    IF (
        Cumulativestock > stock_to_distirubute,
        SELECTEDVALUE ( Table1[Requested Qty] )
            - ( Cumulativestock - stock_to_distirubute ),
        SELECTEDVALUE ( Table1[Requested Qty] )
    )
RETURN
    IF ( myqty < 0, 0, myqty )

    Hi erhang

     

    To solve this situation, first add a calculated column as follows

     

    Adjusted Delivery Date =
Table1[Rquested Delivery Date]
    + Table1[Document Number] / 10000

    Now you can revise the original measure by replacing Requested Delivery Date with Adjsuted Delivery Date

    i.e.

     

    Distributed Stocks =
VAR stock_to_distirubute =
    CALCULATE (
        SUM ( Table2[Stock Qty] ),
        CROSSFILTER ( Table2[Product], Table1[Product], BOTH )
    )
VAR Cumulativestock =
    CALCULATE (
        SUM ( Table1[Requested Qty] ),
        FILTER (
            ALLEXCEPT ( Table1, Table1[Product] ),
            Table1[Adjusted Delivery Date]
                <= SELECTEDVALUE ( Table1[Adjusted Delivery Date] )
        )
    )
VAR myqty =
    IF (
        Cumulativestock > stock_to_distirubute,
        SELECTEDVALUE ( Table1[Requested Qty] )
            - ( Cumulativestock - stock_to_distirubute ),
        SELECTEDVALUE ( Table1[Requested Qty] )
    )
RETURN
    IF ( myqty < 0, 0, myqty )

    Hello,

     

    Thanks for the answer to the original post. I wanted to know if it is possible to add a bit more complexity to the problem by adding another column to table 2.

     

    https://imgur.com/a/gHiCLm7 

     

    Given the image below, and the algorithm already given, how can i include the idea that the stock is not already available at the beginning ? i receive a bit of stock every week (hence my week column in table 2).

    Also, how can i simulate the fact that i might have to distribute the stock during two weeks  because not enough stock (see example in grey )? How can i display the week when the distribution occured ?

     

    Thanks a lot in advance.
