Akito --
This is an interesting question, and I actually had to do some research to give you the correct answer. I am sad to report to you that the answer is no, you cannot create a rule with the requirements you state. When you create a rule, the filtering
criteria only apply to the fields that were updated by the team member, such as Actual Work or % Work Complete. You cannot filter on all other fields, such as Outline Level in your situation. Sorry. But hope this helps.
