License Exclusion Groups
If you are part of multiple projects spanning across different license groups and do not use all the features associated with the license groups, then memberships of multiple license groups can be costly. When you are required to perform actions and use specific Windchill capabilities that span across different license groups, then ensure that you are member of the license exclusion group. The users who are part of the license exclusion group are granted access to Windchill license without consuming the license.
A Windchill License Exclusion Group also enables you to allocate license to test and administrator users without accounting that license against the total license count.
The license exclusion group influences the behavior of the daily active and named licenses in the following ways:
• Active Daily License — When an active daily license user gets license exclusion group membership, then the purchased Windchill license is not consumed. However, if the user consumes the active daily license before acquiring the license exclusion group membership, then that license is consumed and remains unavailable for that day.
• Named License — There are no restrictions on the membership granted to named user license users. For example, if a user has purchased 30 PDMLink Named User licenses and added 25 members to the PDMLink license group, the available count of PDMLink license group will be 5. If license exclusion group has 10 members and added as a member of PDMLink license group, then the available count will remain as 5. Since there is no restriction in membership count for license exclusion group member, the available license count will not get decremented.
Adding Users with Dual role to License Exclusion Group
When you add users with dual roles to license exclusion group ensure that such users dual two distinct User IDs, such that only one ID is a member of the license exclusion group.
For example: John works as a CAD designer and sometimes he is also expected to be involved in post-production analysis. To provide production access to John, the administrator grants him the license exclusion group membership through a new user ID. John now uses two separate user IDs. He uses his regular user ID to perform his work as a CAD designer and uses the new user ID which is part of the license exclusion group for post-production analysis.
