How to count 2 independent variables?

[#1]

Hi:

I have a list of purchases per client and every transaction comes with different products. I need to count as one every transaction per client independently of the quantity. Needless to say, if a customer purchases 2 times, the answer should be 2

Thanks

post sample data please so can help.

The count should be "Destinatario" and "Document". E.G; The first client named "ZAIDA" has 3 different documents, so the answer should be 3.

Try,

Aggr(Count(Documents),Destinatario)

This example is even better, theres 1 customer and 1 document, but 8 different products, and the answer should be 1
