Your Workspace size is continually monitored. As you approach or go over your allowance you receive an alert notification.
The amber alert displays when you reach 75% capacity of your workspace allowance.
The red warning displays when you exceed your workspace allowance.
The alert is also shown when you are in the Manage Models interface.
When you receive an alert regarding your workspace allowance, you can archive any models that are no longer in use so that their size does not contribute to the total workspace size.
If you need more space, contact Anaplan Support.
