One Time Ship To thru Service Connect 9.05.702

I have a workflow where I am attempting to add a One Time Ship To Address to the Order Header table through Service Connect but each time I get an error that the Ship to is a duplicate of an existing Ship To.  I am not trying to add a permanent Ship To.  I have tried to ensure that the field OTSSaveAs is blank which denotes that it is not to be saved.  I am at my wits end so if anyone has any ideas I would greatly appreciate it.
