I'm trying to create a straight table to show me historic forward sales.
I want to see the sum of Sales_QTY where the Order_Date is before a date and the Shipping_Date is after the date.
Example: If the Order_Date is 2022-01-01 I want to sum all Sales_QTY where the Order_Date is smaller than 2022-01-01 and Shipping_Date is greater than 2022-01-01.
