I don’t think it will work, because COUNTIF needs criteria and there is none.
It just must automatically count how many times in a column there was a unique appearance of certain value. How can I specify criteria for “uniqueness”?
Then I would need to show that value per date in a pivot table, but let’s save it for later. So basically, I need how many orders there were per month. This in theory should be a simple task and yet, it feels impossible. Counting manually is not a solution when there are too many orders per month and a lot of order items in each order. It’s easy to do a mistake manually.
I could return the number of orders from different table, but then, how do I do pivot table from different and not compatible sources? The source table I have, have all the data I require, but the order values are repeated multiple times in a row, when there are more order items. So I need to calculate how many orders there were from that.
I found solution for Excel, but since it uses English version of the formula, I cannot find how it is named in LO:
