Hello, folks. I have a problem you might be able to help me with. I have a sheet with multiple sales order lines. I have three columns:
Column A: Item number
Column B: Month (1, 2, ... 11, 12)
Column C: Quantity
There can be several lines for each item number in the same month, so I want an extra column, D, where, if there are duplicate item numbers in column A, the quantities are summed IF they are also in the same month, and if not, leave a 0. From there I know how to make a fifth column where I can retrieve the summed quantities, or the original quantities if there is a 0.
I have tried messing around with some IF, IFS, SUM and SUMIFS formulas, but I can't seem to make it work. How do I do this?
