You can save and load template reports outside the Anaplan XL environment. 

This is done from within the Report Designer.

Once you have set up a grid, use Save to save it for later use. 

Save to a Windows folder: The template is saved as type Anaplan XL Grid. This file can then be emailed or distributed as needed.

To retrieve a saved grid template, select Open Report. Open the template from the saved Windows folder.
