When an expense or request is sent for approval, if the rule used requires approval from a cost centre or cost carrier manager, Moss will first look for the cost centre (or carrier) allocated to the request or expense and then look for the user allocated as the manager of that cost centre (or carrier). That said, for field based smart roles to work, customers must ensure that (a) managers are allocated to each cost centre (carrier) and (b) the field is visible and if preferred set as mandatory for spenders
A manager should be assigned to each cost centre (or carrier).
Configuring automatic cost center assignments ensures that rules take effect immediately, and making the cost center allocation a mandatory field can avoid routing errors.
You can assign managers to cost centers or carriers by following this process:
Click on "Settings" > open up "Accounting"
Go to "Dimensions"
Select either "Cost center" or Cost carrier" > click on a specific cost center or cost carrier
Under the manager section you can now select a Moss user
