How to delete the duplicated records, not just surpress the records?

Question

I am new to CR. Right now I am doing a project which needs CR get query from Oracle. I got the query from Oracle. There are records with duplicated fields. For example (the following only show part of fields):
ID    body_code  
1            10            
2             10            
3             15            
4              15           
5              15           
6              16           
I need to only select records (not surpress, because I will do some caluculate later) like following:
ID         body_code        
1             10         
2              15
3               16   
I tried to creat selection fomula in fomula workshop, shown as follows:
onlastrecord;
<>next
but CR said next can be evaluated. I think it must have something to do with the print-time. So what show I do to delete the duplicated records.Thank you very much.

Answer 1

Ting,
Try this:
Insert a group on body_code.  Then create a running total called Distinct Count.  Field to summarize -> ID, Evaluate on change of group Group # 1 Body Code, and Never Reset.
Then insert a chart in the report header:
In the advanced layout, select body_code on change of and select Distinct Count running total in the Show values.
I hope I understood what you're looking to accomplish.
