Adding Members to the Library Team
The out-of-the-box installation and update of PTC FlexPLM creates two user groups, Retail and PDMUsers. These groups are automatically added to the Members role of the library team. You can use these user groups or create your own user groups to enable access to PTC FlexPLM features.
If you are creating your own user groups, you can add them as members of the library by navigating to the Library > Team page and using the Members table to add PTC FlexPLM users to the role called Members.
Otherwise, add your users to the out-of-the-box Retail or PDMUsers groups.
