I need to hide a element on the main report based upon a field (say X) defined in the new dataset created on the main report. But the problem is, I cannot hide this element as this field X is not appearing under print when expression. Only fields identified on the main report query are showing up here. So how do I hide this element now? Note, I cannot add the query from the dataset (which retrives this field X) to the main report query as that query already returns some other data from the DB.
