Get the value base on lastest date condition

[ngocrin1]

Hi Everyone,

I have order table and delivery table and need to get the exact value (Delivery date & Order ID) as below:

I dont know the way to solve it in Power Query. Has everyone help me?

You will need the orderID in your delivery table as well.. Otherwise there's no way to tell which order the delivery date is referencing.

Tks @Syk . I think if we can add a column with the date range between the day of 2 orders we can lookup exactly the order. But I dont know to do it.

Hi @ngocrin1 

Do you have an OrderID column in Delivery table? If so, you can use Merge queries feature. Select both OrderID and CustomerKey as matching columns. This will match the corresponding DeliveryDate based on OrderID and CustomerKey fast and easily. 

If you don't have OrderID column in Delivery table, you can still use Merge queries feature but select only CustomerKey as matching column. 

Then add a custom column with below code 

let vOrderDate = [OrderDate] in List.Min(Table.SelectRows([Delivery Table], each [DeliveryDate] >= vOrderDate)[DeliveryDate])

Tks. Excellent solution. I don't have OrderID so the "Add columns" step is exactly what I need.
