Security roles can be configured to allow or block access from users to specific parts of Winner. There is also the option to view only for some areas which allows the user to view the values on screen without the ability to change them.
To access security roles at Project level click Global Settings > Security > Edit roles
Note: options will be defaulted to green which means the option is enabled if you click on the empty circle it will change to red which means the option is disabled. For some security roles the option Read only can be selected which will make the circle gold.
We have an article for each group of security roles. Click the links below to view them:
