В АХ 2012 R2 чуть по-другому, но суть та же:

private void dataSourceLoad(QueryBuildDataSource _queryBuildDataSource)
{
    SysDictTable sysDictTable;
    if (_queryBuildDataSource.allowAdd()  == QueryAllowAdd::AllFields)
    {
        sysDictTable            = new SysDictTable(_queryBuildDataSource.table());
        allTables.clear();
        allTables.DataSourceNo  = _queryBuildDataSource.uniqueId();
        allTables.Table_Id      = _queryBuildDataSource.table();
        allTables.Prefix_Id     = _queryBuildDataSource.table();
        allTables.IsOriginalTable = true;
        allTables.PrefixLabel   = this.getDataSourceLabel(_queryBuildDataSource.uniqueId());
        allTables.Tablelabel    = this.getDataSourceLabel(_queryBuildDataSource.uniqueId());
        allTables.insert();
        this.prefixLoad(_queryBuildDataSource,sysDictTable);
    }
}
