Hi Nagaraju,
In usual case DRB will provide the options to include or NOT to include the archived data .
Not sure which report/TC you are using SAP-ISU. Please let u know? Which ever the case may be it can be ABAP modified right?
Please also check with Archive Administrator, If the data still exists in the database even after archiving. In general data is deleted only after every thing is made sure okay from archive perspective. It can be deleted so that it not include in report/TC you are running(not sure on archive flag marked data please check).
Feel free to call me I will try to help 
Thanks,
Kolusu
