Thank you dirk. It was exactly I wanted to do about the username.
I think I wasn't clear enough. Configurations are for grouping Document versions, something like to label documents in the repository.
Help in "Grouping Document Versions in a Configuration" (Core Features Guide > Storing, Sharing, and Reporting on Models > The Repository ).
We intend to have a Configuration management for all aterfacts created on the projects.
Before the scripts do go to production we will label all project documents and we need that this labels are in Oracle file header.
Regards, Jan.
