Hi Navya,
Users and groups assigned to a role inherit the permissions of the role. By default this is end user permission. To change the permissions of the role, see Setting Permissions :
Setting Permissions in the Permission Editor - Portal - SAP Library
In addition you can also refer to the following End User Configuration:
3.4 End-User Configuration - SAP NetWeaver Business Client - SAP Library
I hope this will help you.
Best Regards,
Sharon Dassa
