Limitations¶

Before creating and using any models, model packages, model elements, or model views, please read the following content carefully. The restrictions listed here apply to a single OU (Organization).

The restrictions outlined in this file are default settings. To extend these restrictions, please contact your system administrator. When restrictions are extended, the impact can fall into the following categories:

Current Environment: Once extended, the restrictions apply to every OU within the current environment.
Current OU: Once extended, the restrictions apply only to the current OU.

General¶

The following general restrictions apply simultaneously to models, model packages, model elements, and model views. For instance, if the number of tags that can be added to a single model is extended, the number of tags that can be added to the aforementioned other objects will also extend within the scope of the impact.
