I just designed a pretty and complex ""Monthly Sales by Salesperson"" report for a client, grouping by the AR_Customer.SalespersonNo field and then the client tells me they want to see the sales totals by all of the split salespeople assigned to the account. The standard Salesperson Commission report has built-in logic that groups by all salespeople associated with the invoice but I have to try to figure out how to perform this same grouping on my custom so that I can use the Customer Salesperson assignments. Has anyone ever been successful with writing a custom report that would group by 2 or more of the ""SalespersonNoX"" fields when they exist, or can think of a formula for me to try? Thanks in advance!
