When documents are migrated to the PLM, either by setting them to preliminary in SmarTeam or using the RFC in PLM command*, they are in a frozen state in SmT. Therefore, if people need to edit a document in SmT they must create a new version.
Although this new document will not be visible in the PLM until its migrated itself, the previous version available in the PLM will be flagged as ‘non-current’.

This property can be viewed on the PLM search grid and the structure tab on a CAD Document profile card.

*Documents already released in SmT need to be migrated manually, contact plm-support@cern.ch for help.
