Can i use scheduling from orchestrator? license is ateended

i have attended license
can i schedule process using attended robot license?

From the Robot Licensing page, Attended Robots section:

You cannot start a process from Orchestrator on this type of Robots, and they cannot run under a locked screen. They can be started only from the Robot tray or from the Command Prompt. Attended Robots should only run under human supervision.

If you want to schedule the job you will need an Unattended Robot licence.
