Ax2012 SSRS Report Error

When designing SSRS reports in Ax2012, sometimes when we do changes to report’s temporary tables (like adding/removing fields) the change is not reflected in the report even if we deploy the report or restart the AOS.
I have added a new field in the report temporary table and refreshed the dataset in the visual studio.But the field is not updated in the ssrs report. I tried restarting AOS and deploying the report but none of them worked.Finally i tried restarting the SQL reporting services and it worked.

Restarting the SQL Sever Reporting Services will solve the problem and update the table properly.
