We have only a specific user group that deals with one-off versions. For other users, one-off versions have no value. Therefore, we would like to show/hide one-off version for specific user groups.
Right now there's absolutely nothing in the Windchill data model to differentiate a one-off version from a regular version. Even the Revision attribute value of a one-off version is exactly the same as that of the corresponding regular version. For example, if I create a one-off version for Rev A, the new one-off version's Revision attribute value is still A. Only the the version changes to "A-1,<iteration>".
There is a need for a separate attribute (which acts as a flag) in the data model to clearly differentiate one-off versions from regular versions. This attribute can then be used to show/hide one-off versions.
