I need to analyse the transactions for one group of products. Can I do it?
Check out the Create Subset option in Salesmatrix v4. This allows you to narrow your dataset to a particular section of your market and deal with that data alone. The Create Subset tool creates additional smaller datasets without having to script or reconnect to your original invoicing system. For example if you want to focus on the sales generated by one particular product or from one supplier, or if you want to send the sales data for one state to that states sales manager, then the subset tool makes this very easy.
