I don't think you will be able to do this directly in SSRS.

You have a couple of options. I would suggest you do this in your dataset query but if your tags are correct then it looks like the dataset is not create from a SQL query.

Alternatively you could use a matrix and have a row group by account and a column group by product. Then set the data value to COUNT rather then the default SUM . It won't be in a flat list like you want but might suffice.
