ISSUE / QUESTION:  We have two department managers that cannot approve time sheets via the Time Sheet Approvals module.  Both are members of the proper groups linked to the approval process flow.  

RESOLUTION:   Recommended that the customer add the ‘fmanager’ role to the manager's Employee Position record.  Also, I noticed that the Action Group was not set on the Time Sheet Approval process.   This resolved the issue and managers can now approve time sheets.
