Analysis for Office not refreshing reports on hidden sheets

Hi,

I have created a number of Analysis workbooks connecting to various DataSources in BI/BW.

For the most part this is all working very well.

The only issue I have is that if there is a DataSource inserted on a hidden sheet, this does not refresh when running the prompts.

do I really need to have all sheets unhidden in order for the data source within to refresh upon running the prompts?

Thanks.
