Hi Raghu
After running the repository sync in you Role details does it have Yes for Exists in the System. Also, is the role set as Productive?
You will see these details under the Additional Details Tab of your role in BRM. There will be a drop down for overall Role Status and then a table with each System for the role showing is it exists and if provisioning is allowed.
After checking out those, check if the user is authorised (SLG1 logs will show issue or run ST01 trace).
