POWER BI - 可以递归计算我的 dax 度量的解决方法？

Question

I have 2 tables on orders with the order validity date and in transit stock (stock reaching where the order will be serviced).

(using sample data to simplify for understanding) I am looking for a final calculation like this in my final table -

have done the calculation till column 4 in power BI

if this was in excel i could have simply done

used_stock(2) = serviced(1) + used_stock(1)

avail_stock(2) = total_qty(2) - used_stock(2)

serviced(2) = min(order(2),avail_stock(2))

My base tables look like this -

order table -

intransit table -

I have done the total_qty measure calculation by finding the cumulative sum of shipment quantity for the dates before selected value of order validity date.

I am trying to do the rest of the measures but ending up in circular references. Is there a way I can do it?

edit -

Clarifying it a bit more for the logic needed -

let's say the 2nd order is 15 and the 2nd shipment reaches on 24th, then the base data and output table should look like this -

With present proposed solution the table will erroneously look like -

Answer 1

Try with these below measures-

total_qty = 

VAR current_row_date = MIN('order'[order valid till date])

RETURN
CALCULATE(
    SUM(intrasit[quantity in shipment]),
    FILTER(
        ALL(intrasit),
        intrasit[expected date of reaching] < current_row_date
    )
)

used_stock = 

VAR current_row_date = MIN('order'[order valid till date])

RETURN
CALCULATE(
    SUM('order'[order quantity]),
    FILTER(
        ALL('order'),
        'order'[order valid till date] < current_row_date
    )
) + 0

avail_stock = [total_qty] - [used_stock]

serviced = 
IF(
    MIN('order'[order quantity]) <= [avail_stock],
    MIN('order'[order quantity]),
    [avail_stock]
)

Here is your final output-
