hi Sanjeev,
Request available for reporting has a different symbol than data mart status.
Data mart status means the request has been loaded into further target.IF you post your request any further, you will see the data mart status.
Data mart status is only visible in DSOs. The symbol inside red box below is "Available for Reporting" status. The Blue box is 'Data Mart' status - meaning that request has been loaded furhter to toher targets.
Hope this helps!
Thanks,
Sheen
