Can somehow tell me how to get the average quantity sold per month by the top 3 selling vendors filtered by the type of product? On my data set I have two types of products, which are pre-rolls and carts. I'd like to create a measure that will show me the average monthly sales of the top 3 vendors by quanity sold of carts. I also need another measure of the top 3 vendors by quanity sold of pre-rolls. Thanks in advance.
