To integrate SSRS reports in flex 4.6

[Tushar]

I want to integrate SSRS reports in flex 4.6. I am using IFrame to show SSRS reports in the flex module but i m facing width, height issues, 

sometimes SSRS reports are not getting loaded in the module. Also, I want to pass session details like loginid from flex to SSRS Report.

Require you assisstance.

Thank you,

Tushar.
