MATRIX Ordinal Rank / Top N by category/subcategory

[TCavins]

I'm trying to get the ordinal rank for the following matrix. How would I go about displaying just the Top N results per month in the following Matrix?For example, how do I get only the first 20 records per Month regardless of ties in the Product column?

I've played around with Ranking by products but this gives me more than the Top N as there are duplicates. I've tried determining the number of duplicates but that measure is returning the incorrect value.

I have the rank. I only want the Top N rows regardless of ties. If I want the top 20 rows and I filter on rank <= 20, I'll get more than 20 records due to ties.

Thanks. I wound up breaking the tie by mimicking the MIN example in your link and then adding that to my value in the Rank. Basically guarantees adding less than 1 to every record and thus not distorting the overall rank other than ties.
