Expense AWE workflow for Reviewer

APP 9.1 tool 8.52.16 For Expenses if a reviewer is not assigned to a department in approver assignment, the report will bypass the reviewer and go the the supervisor, however in the worklist tje supervisor is listed as the reviewer. When the supervisor then goes into the report, the reviewer buttons are at the bottom not the approver buttons. However when the supervisor clicks the reviewed button the report goes to APY.  The workflow works correctly if a reviewer is assigned to a department but we will have cases for a department no reviewer is required.
