Non-current Versions

The versions within a version group that are not current:

Can be included as entries on a model object list.
Can be edited like any other model object.
Are subject to the same locking restrictions as other model objects.
Can be documented, copied and deleted.
Have unique implementation names and can be generated and called (external functions only).

For more information on calling non-current versions of external functions, see the Testing an External Function section in this chapter.
