How to get a list of products for a month from the Shop-Products-Reports section without using the bitrix:sale.bestsellers component.
First did this:

CModule::IncludeModule("sale");
    $arFilter = [];
    
    $date = new DateTime();
    $date->modify("-4 week");
    $month_earlier = $date->getTimestamp();		
    $arFilter = [">=DATE_INSERT" => date($DB->DateFormatToPHP(CSite::GetDateFormat("SHORT")), $month_earlier)];
    $db_sales = CSaleOrder::GetList([], $arFilter);
    
    $arOrders = [];
    while ($ar_sales = $db_sales->Fetch()) {
      $arOrders[] = $ar_sales['ID'];
    }
    
    if (count($arOrders)) {
      $dbBasketItems = CSaleBasket::GetList([], ["ORDER_ID" => $arOrders, 'ORDER_PAYED' => 'Y'], false, false, []);
      $arTopItems = [];
      while ($arItem = $dbBasketItems->Fetch()) {
        $arr[] = $arItem['NAME']; 
        $arTopItems[$arItem['PRODUCT_ID']] += 1;
      }
      arsort($arTopItems);
      print_r($arTopItems);
      $arTopItems = array_slice($arTopItems, 0, 50, true);
      foreach($arTopItems as $k => $v){
        $keys[] = $k;
      }

but wrong id's fall into $keys
