Add role assignment option is disabled while trying to assign a role to a user using portal

Question

While I click on the ADD option I find that the Add role assignment option is disabled. How to enable it?

Answer 1

If you don't have permissions to assign roles, the Add role assignment option will be disabled. 

To add or remove role assignments, you must have:

• Microsoft.Authorization/roleAssignments/write 

• Microsoft.Authorization/roleAssignments/delete permissions, such as User Access Administrator or Owner

Ensure you have these permissions.
