Error - 'object reference not set to an instance of an object' when creating an expense

The error 'object reference not set to an instance of an object' occurs if there are no Expense types available for the user to select. You can check if you have any Expense types on the drop down when creating a new Expense. This is likely to be a Tag set up that could be restricting this. You will need to speak to your Access Workspace administrator about this to discuss the best way to grant you Expense types.
