There are many locations in Anaplan where you have the option to insert new data types into your model: versions, modules, users, line items, list entries and dashboards.
On the toolbar click Insert. You can enter as many items need - when you've entered everything, click OK.
You can choose where to insert items by selecting Before, After, Start, or End. The indicator shows where in the list the item will be inserted.
When inserting Versions, you can apply None/Read/Write permissions using the Access Level list.
