Возможно дело в названии ичточников данных, попробуйте использовать QueryBuildDataSource.name() при формировании связки.
Набросал тут упрощенную версию запроса по RAssetLocation:

static void jbRAssetLocationOR(Args _args)
{
    RAssetLocation          rAssetLocation      ;
    RAssetTransferTable     rAssetTransferTable ;
    
    QueryBuildDataSource    qbdsRAssetLocation  ;
    QueryBuildDataSource    qbdsRAssetTransfer  ;

    Range                   rangeRAsset         ;
    RAssetLocationId        rAssetLocationId    ;
 
    Query                   query               ;
    QueryRun                queryRun            ;
    ;
    
    rAssetLocationId = '1 01 01 11 00' ;
    info( 'From X++ Select:' ) ;
    while select rAssetLocation
        where   rAssetLocation.Location ==  rAssetLocationId
        join rAssetTransferTable
        where   rAssetTransferTable.NewLocation ==  rAssetLocation.Location ||
                rAssetTransferTable.OldLocation ==  rAssetLocation.Location
    {
        info( rAssetTransferTable.JournalNum ) ;
    }
        
    query = new Query() ;
    qbdsRAssetLocation = query.addDataSource( tableNum( RAssetLocation ) ) ;
    qbdsRAssetTransfer = qbdsRAssetLocation.addDataSource( tableNum( RAssetTransferTable ) ) ;
    qbdsRAssetTransfer.relations( false ) ;
    
    rangeRAsset = strfmt(   '((%1.%2 == %4.%5) || (%1.%3 == %4.%5))'    ,
                            qbdsRAssetTransfer.name()   ,
                            fieldStr( RAssetTransferTable, NewLocation ),
                            fieldStr( RAssetTransferTable, OldLocation ),
                            qbdsRAssetLocation.name()   ,
                            fieldStr( RAssetTable, Location ) ) ;
                            
    findOrCreateRange_W( qbdsRAssetLocation, fieldNum( RAssetLocation, Location ), SysQuery::value( rAssetLocationId ) ) ;
    findOrCreateRange_W( qbdsRAssetTransfer, fieldNum( RAssetTransferTable, RecId ), rangeRAsset ) ;
    
    info( 'From QueryRun:' ) ;
    info( qbdsRAssetLocation.toString() ) ;
    queryRun = new QueryRun( query ) ;
    while( queryRun.next() )
    {
        rAssetTransferTable = queryRun.get( tableNum( RAssetTransferTable ) ) ;
        info( rAssetTransferTable.JournalNum ) ;
    }
