Changing the Data source in Business Objects XI

Question

Hi,
  Is it possible to change the data source(not universe) in runtime to generate business objects reports. I am using BOXI 3.1.
Below is the code I am using to change the universe in runtime. I would like to change this so that i can change the data source instead of changing the universe. My intention is to generate report from multipple database using same universe. Right now I am using multipple universes connected to multiple datasources to achieve this. I am using Report Engine SDK(Java).
           if("Webi".equals(mDocKind))
               // Added for multiple database support
               DataProviders dataProvs = documentInstance.getDataProviders();
            try{
                //To support multiple queries in BO reports
             for(int count=0;count<dataProvs.getCount(); count++){
               DataProvider dp=dataProvs.getItem(count);
               DataSource ds= dp.getDataSource();
               infoUniverseObjects = getUniverseObject(infoStore,NewUniverseName);
               infoUniverseObject = (IInfoObject)infoUniverseObjects.get(0);
               String newDsCuid = infoUniverseObject.getCUID();
               dataProvs.changeDataSource(ds.getID(), "UnivCUID=" + newDsCuid, true);
               if(dataProvs.mustFillChangeDataSourceMapping())
                    // Re-map data source to target Universe objects
                    ChangeDataSourceMapping mapping = dataProvs.getChangeDataSourceMapping();
                    ChangeDataSourceObjectMapping[] maps = mapping.getAllMappings();
                    dataProvs.setChangeDataSourceMapping();
                }//for dataProvs.getCount()
            }catch(Exception e)
                  mLogger.info("BOReportObject","createReport","Inside multiple data providers loop"+e.getMessage());
Thanks in advance

Hi Shameer,
I think this is only possible with the Universe Designer SDK (which is only available in COM).
Please kindly refer to the API reference for the Universe Designer SDK for more details:
http://help.sap.com/businessobject/product_guides/boexir31/en/bodessdk.chm
Also, please note that changing the universe connection when viewing a document on-demand is not recommended because this could lead to possible issues.
For example:
Two users trying to view documents that uses the same universe at approximately the same time.
But user A wants to use connection X and user B wants to use connection Y.
This could lead to an error while openning the document or while refreshing/retrieving the the data.
Hope this helps.
Regards,
Dan
