# Background processes and scheduled tasks   
   
Processes running in the background in Colleague are called *phantom processes*. Phantoms can be scheduled, and these are called *outstanding* or *scheduled* phantom processes, and are handled by the Envision Process Handler system. Scheduled processes are assigned to an [Operator](../../notes/Colleague/Operators%20file.md) record, a scheduling queue, and the screen that is responsible for creating the process. When creating a phantom process, the Background Execution Type determines if it is a one-time run ("P", Phantom Process) or if a new schedule should be created ("E", Envision Process Handler).   
   
## Phantom management screens

- **MYPR**: Shows active scheduled processes for the logged-in user, Detail takes you to the associated **PHTS** Detail screen from **PRSC**   
- **OPRI**: Shows all currently scheduled processes, their associated process queue, and when they will next run.   
- **RPRI**: Shows all running processes for the logged-in session.
