Please i need to create a Master-Detail report in RS, that is the first record in the master query is displayed then all its related records from the Detail query, the second record from Master... and so on..

how can i do this? can i have any workthrough? i tried the subreport but seems i didnt catch the correct way to implement it, the subreport expected the sum of the master table IDs as a parameter while it should consider each ID from the master and repeats itself for each ID...
