Sending unchanged data on a confirmation statement

If we accidentally send in unchanged data on a CS01, which would otherwise have appeared on an AR01 (say sic codes, statement of capital or shareholder info) will the confirmation statement be rejected?

I am particularly concerned with the period after June 30th before we can confirm that companydatarequest is working OK thereafter, as you provide no test facilities for this call.

The SIC codes, capital and shareholders requirements are the same as for the annual return in that changes can be notified on this document. We are asking for all the shareholders, rather than changes, to be submitted to CH via software filing packages. However the software providers need only ask their own customers for changes to this data.
