Expense Report Status Definitions

Summary:

We need an official documentation showing the definitions of various expense report statuses, and clarification on the difference between "manager" approval and "individual" approval.

Content (required):

A business user audits expense reports for checking fraud and she needs to know what the different expense report statuses mean (i.e. status definitions, not the status names).

We tried to find an Oracle document containing the information she needs, but the best we found was Doc ID 2666454.1, which is incomplete. Below are all the statuses which we can see from our end. We're hoping to get the official definitions and meaning of ALL these statuses for her analysis.
