Why did the workflow stop responding?

In change orders and new item requests, the workflow can stop responding due to one of the following reasons:

• Approval rule has an empty approval group.

• Approval rule not being associated with an approval group.

• An invalid approver. The user or role selected as an approver doesn't exist in the application.

• One or more lines don't match any rules in the approval task.

• Extensible flexfields not being generated.

• Inactive rules.

• Rules unavailable for the header stage.

• A new item request definition step assigned to a role and the role not being assigned to any user.

• An error in SOA workflow. Use Enterprise Manager to view workflow errors.

• Use of an incorrect case to specify the value of a parameter such as priority code.
