Calculating the number of periods

[Anonymous]

Hello,

i want to calculate the number of periods of sales for each product.

For example, for the product "ADVANCE" we have 5 periods available, how can i calculate this number?

I used the function count but i think that i used incorrectly. Can i help me please? I really need it.

Thank you,

best regards,

Alâa Eddine.
