Hi Ryan
For your information.
1. I think Graeme Ham will report to Patrick OLLIVIER. Because Mr.Patrick is Chief Human Resource Officer Asia Pacific. That mean he should be his/her direct boss.
2. For below error screen, Normally IT Workflow can assign to only one of head of department.
Example.
If you submit IT Workflow to Director of Human Resource after that you know now he/she was on vacation. So you will resend IT Workflow again but this time You send to Human Resource Manager.
At the same time if Director of Human Resource see your email and He/She will approve your request the result will like your error screen. Because you already assign this permission to Human Resource Manager.
