If your universe has multiple star schema, having more than
1 fact table is natural. The issue, however, is when we
have more than 1 fact table in one star schema formation.
This is because, that would lead to fact to fact join -
which is normally manay to many cardinality join. For more
details and to understand the concepts, read this:

Regarding Hyperlinking in Business Objects. We have a few reports in QA environment where a number of hyperlinks are employed using OpenDoc function.In some of the reports,hyperlink is used to move to another tab within the same report.The formula used include "DocID" and ReportName="tab name".This works fine but now,for the PROD move,this will not work as the Doc Ids are subject to change. Is there a way to overcome this?Without DocID,how will move to a particular tab? Thanks in advance
