php - limit by subsidiary and transaction type

Hi,

I have script now that can pull transactions for a date range but want to only pull salesorders and invoices for a subsidiary.

for($a=0;$a<365;$a++)
{
    unset($itemSearch);
    $itemSearch = new nsComplexObject('TransactionSearchBasic');
    $sum = 20+$a;
    $sum2 = 21+$a;

    $date = date("Y-m-d",mktime(0,0,0,4,$sum,2009));
    $date2 = date("Y-m-d",mktime(0,0,0,4,$sum2,2009));

    echo"\n$date <br>";

    $itemSearch->setFields(array("dateCreated" => array( "operator" => "within",
                    "searchValue"   => "".$date."T00:00:00.000-07:00",
                    "searchValue2"   => "".$date2."T00:00:00.000-07:00" )));
    $myNSclient->setSearchPreferences(false, 1000);

    $searchResponse = $myNSclient->search($itemSearch);
    $js = json_encode($searchResponse);
    $file_name = "tmp/$date";
    file_put_contents($file_name,$js);
}

Any ideas?
