Hi Tanisha,
I also think its some authorization issue please check with Basis team.
there are other ways also we can check data from infoprovider
1)For DSO go to manage tab and click on active table and execute
for cube also go to manage tab and content
2)you can open your infoprovider in analyzer aslo to check the data
open Bex analyzer open query select infoprovider and click it will show the data then you can drill down with specific char to validet.
Hope it will helpful.
