This is my first post, though I have been visiting for a little while.
I have an issue that I hope somebody can help with and hopefully improve my understanding at the same time.
I am trying to find the frequency of basket sizes against a set of sales. I have a unique identifier for a sale as [Sales invoice] and I count the unit quantity by line item (product) as [Units Sold].
My attempt to find the above is to use the following:
AGGR(SUM([Units Sold]), [Sales invoice])
However this results in inaccurate quantities. Where the above should show (Basket Size 4 = Frequency 2, Basket Size 7 = Frequency 1), instead it is showing inflated numbers which do not seem to match anything I can find.
Hopefully I have explained that clearly, any help would be much appreciated.
