Orion has a default setting and uses a semicolon between concatenated fee transactions.  You can change this to a period (or other character) through Invoice Style Settings (you will need to change each Invoice Style).  Go to Billing Manager and choose TOOLS, Invoice Styler.  Locate, highlight and click the EDIT Button on the Invoice Style you want to edit.  Once the invoice style is displayed, choose Invoicing, Settings and change the character in the Concatenate – Separator field. Click OK to close System Settings, and then save your Invoice Style.
