When employees submit a claim from Self Service, they will only see who the 1st level approver is because they will need to select their name from a dropdown list before submitting the claim.
However, they will not see the 2nd or 3rd level approvers.
Once the claim is approved by the 1st level approver, employees will see in their Self Service menu that the claim now has the status 'Authorised'. This means the claim is awaiting approval from another approver, but employees cannot see the name of their next approver.
This is also the case for System Owners, who can only see the status of each claim in the Payroll menu.
