Dear Leslaw,
yes, i am using some time characteristics (Posting Date, Clearing Date & Netdue Date)in columns to derive ageing. wrt to your earlier post i have created aggregates on those time characteristics too..and executed the report in RSRT, still it is showing usage as 0 and last used column as blank. Below is screen shot of RSRT.
In RSRT screen shot it is showing that my query is not using aggregates, what would be the reason for this?
Regards,
PRK
