I need to find out how many of the different items I sold last year. As my stock administrations was extremely messy, due to all the Tryton introduction troubles, I should sum it up over all sales, and not calculate it on base of stock moves.
I found the sales > report > sales menu item, tried “per item” and per category, but always end up with an empty window. (I choose a period of time and a warehouse as well). What could I do wrong - or should I try another approach?
