BEx Analyzer workbooks as precalculated documents can be generated using the BEx Broadcaster. For more information, see Precalculating and Distributing Workbooks.
The precalculated documents with historic data are stored in Knowledge Management (not in the BI system).
You can use the Portal Content Studio to create iViews with precalculated workbooks. The iViews are of type KM Document iView and have the code link com.sap.km.cm.docs. The most important property is the path to the document. You can use the KM-Content iView from the Content Administration portal role to determine the path for the document.
For more information about other iView properties, see iView Properties.
