Issue putting in mileage expense claim under different operating unit - additional information not s

Hi, I am hoping someone could be able to help again.  We have been running with Internet Expenses in Northern Ireland Water for the last year but we have been asked to set up a new instance of Internet expenses under a different operating unit.  So that expenses specific to the employees in the new operating unit can only be viewed by them. Our current operating unit is called WS Organisation and our new operating unit is called NIW Alpha.  Employees under the new operating unit would access Internet Expenses by using a customised Internet Expenses responsibility with the operating unit attached accordingly via the MOsecurity profile. We have set up a number of new expense types for the new operating unit and they are available to select but for some reason the additional information entered under the expense type is not being saved,
