Item Sales Report Product Sales Breakdown Sorting Order

Is this something we can control with Product Tag?

If this is sorted, then I would be able to easily see in order all my different breakfasts to differentiate what is the top seller for a particular category.

so can this be sorted?

i would also like to know in what sequence or logic the report is been shown

Yes you can do this. I will be building some reports along these lines soon. Look here for more syntax. Specifically look at syntax that deals with Tickets and Orders. With fields and expressions you should be able to build a nice report. We may need to request a few things along the way as he is still improving it. But please feel free to play around with it and learn it. The more people that learn this and attempt to use it the faster Samba matures and develops
