Reversed loop over dates

Anonymous — Mon, 11 May 2020 14:58:44 GMT

Hi,

I'm trying to make a model that can predict if I can deliver a certain plant from stock. Lets say that the plant takes up 2 quantity of "Item 1". Then I want to make a revesed loop from the largest date which is the 30/07/2020 and stop when it is no longer possible to deliver the item which will be on the 30/05/2020. It means that my possible delivery date is the 15/06/2020 because from that date I can deliver all the dates in the future from the known data.

How do I make a measure that can poste this date for me?

Quantity Accumulated

Transaction quantity

Stock 40

15/05/2020 -13 27

30/05/2020 -26 1

15/06/2020 10 11

30/06/2020 -3 8

15/07/2020 -4 4

20/07/2020 10 14

30/07/2020 -5 9

File attached. The code works the way you wanted... but I don't think you have considered all the possible arrangements of dates and quantities.

Hi,

Yeah it didn't solve it. The task I had seems to be difficult to solve with dax.

It was solve using SQL instead.

It's not difficult to solve with DAX. Problem is you have not defined the full logic. But if your SQL works - great 🙂
