There is currently an issue with the 2014 Workgroup/Professional if you map a Vault Property to an Inventor System property that the Inventor System property is not updated when synchronizing properties via Jobserver.
For example you create a mapping from Vault System Property "Initial Approver" to the Inventor System Property "Engr Approved By":
Changing the file to released will fill the "Initial Approver" in Vault with the user name and a job to synchronize properties is executed.
However you realize (after successfully running that job) on this Inventor file that the "Engr. Approved By" is still empty:
This issue doesn´t occur if you map the Vault Property to an Inventor user defined property.
