Forecast shown by Group in forecast screen

Hi, 

I have a question related to FORECAST.  #Forecast Type  #Forecast Tab

I need to have a forecast by product (not by family), so I have not checked the group by family set up.

I have 2 issues. One, I'm not able to see the forecast split in products (only family group when the checkbox of family is true) and I'm not able to choose Quantity in any forecast type.

What setup did I miss?

Thanks in advance

Veronica
