Overview of Additional Workflow Controls
You can use additional workflow controls to control actions by participants in a change workflow.
You can add up to five roles as participants so that users with the configured role can take specific actions on changes. For instance, you can allow users with the role Engineer to manage affected objects.
In short, you can control which actions change participants can perform at each status in the workflow. You can also use Additional Workflow Controls to edit the attributes of the changes through the standard option of Manage Change Header Attributes.
Before update 25D, a user’s permissions and actions in a workflow were determined solely by the configuration in the additional workflow controls. This setup defined whether a user could serve as a Creator, Requestor, Assignee, or another role.
Starting with update 25D, the application validates both additional workflow controls and access control lists to determine what actions a user can perform in a workflow. This validation is applicable only when the profile option named Enable Access Control List for Workflows is enabled. If either control is missing, the user can't perform the action or access the object. For more details, see the related links.
