Enabling User Access to PTC FlexPLM through Team Membership
In PTC FlexPLM, system administrators must assign all PTC FlexPLM users as members of the team for the Windchill library that contains the PTC FlexPLM business object data. This requirement also applies for external vendors who access PTC FlexPLM data through the vendor portal. In a typical installation, the Windchill library that contains PTC FlexPLM data is named RFA. The name of the library is defined at the time of installation. The name can most easily be identified by looking in the custom.lcs.properties file for the value of the property:
com.lcs.wc.util.flexContainer.libraryName
* 
If the PTC FlexPLM server is also being used for independent CAD Data management by another business unit that does not require access to PTC FlexPLM, do not assign those users as members to a role in the Windchill library that contains the PTC FlexPLM business object data.
