Drill in Webi reports via Java SDK

Question

Hi!
Is it possible to programatically drill up\down in Webi reports? I'm looking throught RE documentation - there are interfeces providing drill functionality (DrillInfo etc). But I can't understand how I can drill in InfoObject instance or may be I can schedule a report with a drill on?
I need to create a code that will create the instance of docement with drill by some dimensions..
Thanks a lot

I try to use this part of code and get an exception.. (list all dimensions and then try to get hierarhies for drill for al least one of them)
                        // drill
                        // get a report
                        Report objReport = doc.getReports().getItem("Main");
                        // DrillInfo - information about drill of a report
                        DrillInfo objDrillInfo = (DrillInfo) objReport.getNamedInterface("DrillInfo");
                        // add a new drill element from
                        // Path where to drill
                        DrillPath objDrillPath = objDrillInfo.getDrillPath();
                        objDrillPath.setAction(DrillActionType.UP);
                        DrillFromElement objFromDrillElement = (DrillFromElement)objDrillPath.getFrom().add();
                        DrillToElement objToDrillElement = (DrillToElement)objDrillPath.getTo().add();
                        // get dimensions - here is a wrapper around report query
                        Metric metrics[] = query.getMetrics();
                        for (int i = 0; i < metrics.length; i++) {
                            Metric metric = metrics<i>;
                            if (metric.getQualification().name().equalsIgnoreCase("DIMENSION") ) {
                                DrillHierarchies drillHierarh = objDrillInfo.getContainingHierarchies(metric.getUnderlying().getID());
                                if (drillHierarh != null) {
                                    objFromDrillElement.setObjectID(drillHierarh.getItem(0).getID());
                                    objToDrillElement.setObjectID(drillHierarh.getItem(drillHierarh.getCount() - 1).getID());
Line
DrillHierarchies drillHierarh = objDrillInfo.getContainingHierarchies(metric.getUnderlying().getID());
causes
java.lang.RuntimeException: com.businessobjects.rebean.wi.ServerException: An internal error occured while calling 'getDrillBar' API. (Error: ERR_WIS_30270)
I can't understand why. I get this error even if i send ""  as a parameter.. In documentation it is written that it is and ID of dimension. Could you please help me, or may be It is impossible to to set drill elements and drill in this way?
Big Thanks!
