Activity lookup based on project Id

Hi,

I have a requirement to make an activity lookup based on the project id as same as in all timesheet form for this i override lookup method of control and use the following code please consider bellow screenshot.

public void lookup()
        {
            //super();

            Query                   query = new Query();
            QueryBuildDataSource    qbdsSmmActivities, qbdsProjTable, qbdsActivityParentLinkTable;
            QueryBuildRange         qbrActivityParentLinkTable, qbrProjTable;
            QueryBuildLink          qbl1, qbl2;

            SysTableLookup  sysTableLookup = sysTableLookup::newParameters(tableNum(smmActivities), this);

            sysTableLookup.addLookupfield(fieldNum(smmActivities, ActivityNumber));

            qbdsSmmActivities = query.addDataSource(tableNum(smmActivities));

            qbdsActivityParentLinkTable = qbdsSmmActivities.addDataSource(tableNum(SmmActivityParentLinkTable));
            qbdsActivityParentLinkTable.relations(false);
            qbdsActivityParentLinkTable.joinMode(JoinMode::OuterJoin);
            qbdsActivityParentLinkTable.addLink(FieldNum(SmmActivityParentLinkTable, ActivityNumber),FieldNum(smmActivities, ActivityNumber));
            qbrActivityParentLinkTable = qbdsActivityParentLinkTable.addRange(fieldNum(SmmActivityParentLinkTable, ParentType));
            qbrActivityParentLinkTable.value(queryValue(smmActivityParentType::Project));

            qbdsProjTable = qbdsActivityParentLinkTable.addDataSource(tableNum(ProjTable));
            qbdsProjTable.relations(false);
            qbdsProjTable.joinMode(JoinMode::OuterJoin);
            qbdsProjTable.addLink(fieldNum(ProjTable, RecId), fieldNum(SmmActivityParentLinkTable, RefRecId));

            qbrProjTable = qbdsProjTable.addRange(fieldNum(ProjTable, ProjId));
            qbrProjTable.value(XYZ.valueStr());
            
            sysTableLookup.parmQuery(query);
            sysTableLookup.performFormLookup();
        }

But I am unable to get the filtered values of activity numbers based on project id.
