An ITP Model can be outdated for two reasons:
In other words, the outdated [in development] model revision cannot be recreated exactly as it is in the current state.
Note
Deleting, renaming, or moving elements in the Data Definition component of a Data Backbone will outdate the ITP Models based on this Data Backbone. Additions to the Data Definition component will not outdate the ITP Models based on that Data Backbone. Any changes to the Data Retrieval component of the Data Backbone will also not result in outdated ITP Models.
Creating the ITP Model will make it up to date again, reflecting the changes to the Data Backbone revision or the document revision(s).
When an outdated ITP Model is unlocked the outdated [in development] revision is changed into a revision proper, but not made the [current] revision.
