Roles in NetSuite are an efficient way to delegate specific permissions to Employees. If we need to set one default role for the employee those who had multiple roles
The steps are as follows
Step 1: Navigate to the View My Roles Page
In the top right corner of NetSuite is the login information drop-down. Hovering over the Employee name will list the several options. Click the “View My Roles” option. This will bring to the page where a default role can be selected.

Step 2: Set a Default Role
On the “My Roles” page, a user can easily switch between roles, hide roles, or select a default role. To select a default role, hover over the button with three dots on the role of choice. Then there is an option to make the role default.

Once a default role is selected, We can automatically sign in to that role whenever log in to NetSuite.
