Forum Post: Create a report using the Sales Invoice data and Vendor Invoice Data

Hello, We are running Sage 50 2016. We direct ship the majority of our sales. We have some inventory but more non-stock. Each type of product has a Non-Stock item defined in our inventory. Items direct shipped are invoiced using the Non-stock inventory item. The Customer invoice number is then recorded on the Vendor Invoice(s). I'd like to create a cost of sales report by salesrep using these two data files. Has anyone done this already? Can it be done within Sage 50 or do the files need to be exported then processed? Thank you for your assistance. Ellen
