cognos - Combining Results from 2 Queries. 1 of Which is a Joined Query -
i have 2 list's display data , provide totals.
one joined query, other single query
i have tried join joined query , single query can't work.
im trying calculate return rate. first list produces total return amount each salesman. second produces total sales each salesman.
in 3rd list im trying add , divide totals return rate.
this can achieved using master details report. 
 great simple example can found in following video tutorial here:
