Ordering Change Only Updates

In the online ordering system you can choose to set up an automated COU order to be either every 2 months or every 6 months from the date you place a full supply order. The COU option must be selected at the same time as the full supply. Retrospective manual COU is no longer possible.

For example:-
Full supply order on the 15th April will generate a COU 
2 months later on the 15th June or
6 months later on the 15th September depending on which option is selected on the 15th April.

You can also choose to have a Feature Validation Dataset- FVDS- file sent with your COU.

Please note COU can only be applied to CD/DVD and FTP orders.

Products with a Download option can only be delivered as full supply orders.
