I've created a scheduled data extract and suppressed a number of fields. When I connect to that data source in desktop i only see the fields that are visible. When I connect to the data source through web authoring I see the hidden dimensions with an exclamation attached. What's up with that?
Alas, no love here on the forum. I noticed that the ghosting fields are from a table join that was in the data source but removed. Something was causing those dimensions to hang on. I ended up rebuilding the source in a new workbook and everything works as it should.
