The New Constructed Inventory Feature https://docs.ansible.com/automation-controller/4.4.0/html/userguide/inventories.html#constructed-inventories is the successor to the existing Smart Inventory feature, and is now presented as another choice when creating an Inventory in Ansible Automation Platform controller.
After you click “Add constructed inventory” under Inventories, this is the menu you will see: There are three key items unique to constructed inventory. Input inventories is where you will list existing inventories that the constructed inventory will get inventory content (hosts, groups, etc).
Let’s look at groups for this particular example: When the constructed inventory update ran, it copied the “account_1234”, “account_4321”, and the “accounts” groups from the input inventories into the resultant constructed inventory.
