Unique product ids bought

[catalinmartin]

Hi guys,

I've created a metric showing me the unique products ids from an order. I have used approx count distinct and works as expected if I user Order id as dimension & this new metric.

Now, I would like to know for a specific month, for example, number of unique product ids bought. Do you have any suggestions on how the definition of this new metric should look like? The same metric will return less volumes than expected (something like 50% less).

Any hint will be much appreciated.

Thank you in advance.

Yeah, if you put order IDs inside approximate count distinct, then use that calculated metric against a month dimension, that should give you what you're looking for.
