You cannot assign users to a role within Power BI Desktop. This is done within the Power BI service. You can enable dynamic security within Power BI Desktop by making use of the username() or userprincipalname() DAX functions and having the proper relationships configured.
Manage security on your model
To manage security on your data model, you will want to do the following.
- Select the ellipse (…) for a dataset.
Select Security.
This will take you to the RLS page for you to add members to a role you created in Power BI Desktop. Only the owners of the dataset will see Security available. If the dataset is in a Group, only Administrators of the group will see the security option.
You can only create or modify roles within Power BI Desktop.
Working with members
Add members
You can add a member to the role by typing in the email address, or name, of the user, security group or distribution list you want to add. This member has to be within your organization. You cannot add Groups created within Power BI.
You can also see how many members are part of the role by the number in parenthesis next to the role name, or next to Members.
Remove members
You can remove members by selecting the X next to their name.
RLS has changed several times with each new update so this can change soon.
