If your environment's approval type is based on organisation roles and groups, approvers can be missing on the expense report in portal if they aren't assigned the correct organisation role.
An expense approver can be assigned any of these roles:
Line manager (LM)
Expense approver
Reports to manager
To determine what role is used on your environment, check the following in portal.
Click Administrator Dashboard, then click Site Manager.
Click Admin Settings, then search for expapp_org_role. If this is set as MGRESS for example, this means the reports to manager role needs to be assigned to approve claims.
To assign the organisation role to approvers on portal, follow the steps below.
Click People Management, then click Data Centre.
Click People Management, then search for Maintain organisation roles
Click Maintain Organisation Roles, then click the relevant Organisation Group item from the dropdown menu.
Click Find, then from the role drop-down list, select the relevant role, e.g Reports to Manager.
