AWE Journal Approval

We use the Approval Framework for our GL Journals. It's set up so that every journal goes to a supervisor for approval. Anything over $200k is sent to our Controller/CFO for approval, regardless of who the supervisor approver was. We thought that the supervisor approval was based on who created the journal, but recently discovered that it's actually based on who submitted the journal for approval. This could potentially allow the creator of the journal to be the approver of the journal, which is a huge no-no for us. We also discovered that a workflow admin can re-assign the approval
