Crystal Reports - Two Tables in one report, grouped by machine.

Question

I have two tables for machine schedules.  One is a Current Job Table, and the other is a Que Job Table.  I do have tables joined to a definition table for the machine name.
Cur Job Table - Def table
Que Job Table - Def table
I want to report the information from the current job table for each 13 machines in sequence.  Some machines may have more current jobs than qued jobs.
...Machine 1 (Machine Name)
.....Current Jobs (Cur Job Table)
.....Qued Jobs (Que Job Table)
...Machine 2 (Machine Name)
.....Current Jobs (Cur Job Table)
.....Qued Jobs (Que Job Table)
Etc.
Is there a way to do this easily?  I have tried grouping and sub reports.  Seems like I end up with duplicate records due to the SQL joins.

Sharon,
Select distinct will not work here, as select distinct checks all fields in the record, and when joining the two detail tables, it will not clear out "duplicates" on only one side of the join.
I would also humbly suggest that using Select Distinct to try to "clean up" a query is rather dangerous.  You may end up dropping some data that should appear on the report.  (In fact I recently had to fix a report due to this issue - coded by someone else, of course!  :->)  If you are getting duplicate records and you don't want them, the query should be coded to produce the desired result set WITHOUT the Distinct clause being the reason duplicates are dropped.  (This is not to say that select distinct is not useful, or should never be used.  If you need a distinct list of customers over a date range, using Select Distinct custcode from sales where date between {?start} and {?end} is perfectly OK.)
