License Allocation

This topic has the details of the Windchill process that automatically determines the effective license for a user, prevents common license misconfiguration, and ensures accurate license consumption reporting. Assigning a single user to multiple licenses with overlapping capabilities, either unintentionally or due to unclear understanding of license entitlements can result in over-consumption of licenses, paying for licenses that are not actually required, and confusion when reviewing license usage and reports.

Determining the Effective License

The system uses the ranking rules to determine the effective license. In case of license misconfiguration, the system automatically corrects the problem and accurate record of effectively consumed licenses is maintained. The effective license is determined when any of the actions listed here occurs.

• A user or a group is assigned to a group or license group.

• A license file is imported manually into the system.

• A license file is fetched from PTC for a connected Windchill instance.

• The method server is restarted.
