I have a dataset with variables as "SalesID", "ActualSales" , "TargetSalesAmt" and "Region". I need to create a performance index based on total sales achieved against the target set, and identify the best performing region overall. How can this be done without using Proq SQL. Example:- SalsID ActualSales TargetSales Region XE908 19000 13800 East XA908 20000 18000 East XC102 25000 30000 West XB102 15000 18000 East XA908 20000 22000 West XE908 10000 10000 North XB102 30000 25000 South
