Re: Need a simple report showing who owes me what based on product or class. should be easier than this
Yes that is a difficult analysis at the AR level. A sales analysis by item & class would be easy. But AR is maintained per invoice - and invoices can each contain multiple products, and maybe classes too. So QB isnt going to cough this up easily.
Possibly you can use the 'customer type' field as a way of segregating sales - and that can be used within AR reports.
You might be able to get there by creating a sales analysis, and then filtering it down based on invoice status = "open"- but i've never tried that.
