If you have a template which results in an empty interview, then the interview can be suppressed using the command «HideEmptyInterview(Yes)»
The question is, why would you have such a template? It could be that the template consists of fillpoints which merge in data from a data source, for example, and that the data elements are all excluded from the interview (using the ExcludeFromIv command).
This command is available in Version 4 of XpressDox.
