hi,
Like Matthew mentioned, you can sort the data in master data by sorting thedata in your end routine code. If you want to view the records in descending sort order, you can just use the sorting buttons available in the display output page for that. If you want the output in descending order in your report, you can put the sort functionality at the bex query level.
May I know your requirement here, why and where you want to display the sorted data?
Regards,
Rathy
