Unattended automation

Unattended automation is a process whereby machines perform tasks on their own, without the need for human intervention. Such tasks are usually:

  • complex

  • repetitive

  • carried out in batches on large amounts of data

And with the help of unattended automation, they become:

  • fast

  • scalable

  • reiterative

  • immune to errors

  • inexpensive

  • able to be run around the clock

Important:

Important: Unattended automation requires elevated permissions, access levels, and credentials, which makes it best suited for highly privileged operations.

Unattended automation is performed by unattended robots, which are deployed from Orchestrator and are programmed to execute based on a certain configuration. They run in the back-end, on dedicated machines, so users never need to interrupt their work to trigger a process.

In a nutshell, these are the components that make up an unattended automation:

The components above, as well as other concepts that are essential to unattended automations, are defined below, in the Useful concepts in unattended automation section.

Necessary permissions

This option is available to you if you meet the following permission criteria:

  1. Role permissions

    1. Machines - View, Create, and Edit

    2. Users - View, Create, Edit, and Delete

    3. Robots - View, Create, and Edit

  2. Organization Administrator role - this is needed in order to create an account at the organization level and assign it to the Everyone group.

  3. Tenant Administrator role - this is needed to create robot accounts from the Unattended setup page.
    Note: If the Create new robot account button is disabled during the unattended setup flow, the current user likely does not have sufficient permissions. In addition to the Orchestrator role permissions listed above, the user must have the Tenant Administrator role in the tenant to create robot accounts.
  4. At least one of these four action combinations:

    1. You have permission to view and edit robot units.

    2. You have permission to view robot units and edit subfolders.

    3. You have permission to view subfolders and edit robot units.

    4. You have permission to view and edit subfolders.

Roles

The following roles are automatically allocated:

  • When creating a robot account, the Allow to be Automation User tenant role is allocated.

  • When selecting a folder, the Automation User folder role is allocated.
