Hi Venkitta,
Do you mean that all projects are duplicated in adhoc view?
If you select projects on adhoc view, they are duplicated in report?
Could you provide more details about duplicate?
Did you run Load Data Warehouse job with Full option?
It will truncate DWH tables and re-insert records from PPM tables.
(DWH tables will be synchronized by current PPM tables.)
After Load Data Warehouse job with Full option, duplicated records may be removed.
Regards,
Shoichi
