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
