In Magento 2.1.7 after adding new product i can't create new entry in stock id. It create only default stock qty and i can't add the others.

Now I found how add Stocks per zone, but after set it i can't close checkout anymore. After some debugging i found where error is generated:

• Magento\Quote\Model\QuoteManagement -> placeOrder
• checkout_submit_before event to Magento\CatalogInventory\Observer\SubtractQuoteInventoryObserver

  $this->stockManagement->registerProductsSale(
  $items,
  $quote->getStore()->getWebsiteId()
  );

• Magento\CatalogInventory\Model\StockManagement in condition

 if (!$stockItem->hasAdminArea()
                && !$this->stockState->checkQty($productId, $orderedQty, $stockItem->getWebsiteId())
            ) {
                $this->getResource()->commit();
                throw new \Magento\Framework\Exception\LocalizedException(
                    __('Not all of your products are available in the requested quantity.')
                );
            }

the error is placed in condition $this->stockState->checkQty($productId, $orderedQty, $stockItem->getWebsiteId())

Please help

Thanks
