When modeling an activity, you assign it to a Role according to who is responsible for completing the activity. Each activity (that is each Activity Node, Voting Activity Node, and Compound Activity) must be assigned to a Role. If an activity is not assigned, the process instances created from the process definition will go into error state.
You can assign an activity
To a Role
To particular users in a Role
This section explains how to assign activities to Roles. Refer to section 11.2.1 Assigning an Activity to a User for instructions on how to assign an activity to particular users.
To assign activities to roles:
Select the Activity Node, Voting Activity Node, or Compound Activity.
In the General tab of the Properties view type the name of the role, in the Role field in the Assignee area.
