Release : 14.X
Component : CA IDENTITY SUITE (VIRTUAL APPLIANCE)
There is no out of the box way to hide "Role Management" menu in in Identity Governance.
There is no configuration option in the product that allows this.
The only way to do it is to find in the ear the css file that controls the display, set it to hidden and redeploy the ear.
This is unsupported as on the next patch or upgrade it will be overwritten and set back to the out of the box file
