# Roles and Performers

**Roles** are assigned with **Tasks** and each **Role** in a **Bpm Process** can have **"N"** **Tasks**. But a **Task** can be assigned to only one **Role**. One **Role** per **Task** is enough in most of cases but there are situations where a **Task** must have more than on **Role**. For these situations **Performers** are used. **Performers** are also **Roles** but more than one **Performer** can be assigned to a single **Task**. When **Performers** are used **Bpm Lanes** are ignored.

Check how to do this at **Design Time** in the following link: [Roles and Performers](/project/application-manuals/backoffice-manual/main-menu/processes/define-new-process/performers-and-roles.md)

**Performers Implementation**

When **aBpmUser** take **aBpmAssignment** then a worker is added to the **BpmTask**. The instance variables \[***rolesWhoWorked***] and \[***usersWhoWorked***] are only used when performers are set.

Internally when **aBpmTaskAssignment** is finalized and it has **Performers** then the **BpmProcessInstance** do NOT generate next tasks. The **BpmTaskAssignment** is released (#free) and the next **Performer** is now able to take it.
