Salable quantity won't update from 0 in Magento 2.4.4

Question

I'm trying to update product quantities when something sells or is revised on another selling channel. I have a platform notification which is received, and everything works fine except when I'm trying to revise an out of stock product. In this situation, the quantity will change, buy the salable quantity will not. If I then locate the product in Admin->Catalog->Products and save it without making any changes, the salable quantity will update. What am I doing wrong?

My code is below.

 public function updateProduct(string $sku, int $qty): void
{
        $sourceItem = $this->sourceItemFactory->create();
        $sourceItem->setSourceCode('default');
        $sourceItem->setSku($sku);
        $sourceItem->setQuantity($qty);

    if ($qty > 0) {
        $sourceItem->setStatus(SourceItemInterface::STATUS_IN_STOCK);
    } else {
        $sourceItem->setStatus(SourceItemInterface::STATUS_OUT_OF_STOCK);
    }
    $this->sourceItemsSaveInterface->execute([$sourceItem]);

    $this->reIndex();
}

I got it. I had to update the stockItem after saving the sourceItem. Below is full working code.

use Magento\InventoryApi\Api\SourceItemsSaveInterface;
use Magento\InventoryApi\Api\Data\SourceItemInterfaceFactory;
use Magento\Framework\ObjectManagerInterface;
use Magento\Inventory\Model\SourceItem\Command\GetSourceItemsBySku;

class UpdateProduct
{

/** @var SourceItemsSaveInterface */
protected $sourceItemsSaveInterface;

/** @var SourceItemInterfaceFactory */
protected $sourceItemInterfaceFactory;

/** @var GetSourceItemsBySku */
protected $getSourceItemsBySku;

/** @var ObjectManagerInterface */
protected $objectManager;

/**
 *
 * @param SourceItemsSaveInterface      $sourceItemsSaveInterface
 * @param SourceItemInterfaceFactory    $sourceItemInterfaceFactory
 * @param ObjectManagerInterface        $objectManager
 * @param GetSourceItemsBySku           $getSourceItemsBySku
 //* @param SourceItemInterface           $sourceItemInterface
 */
public function __construct(
    SourceItemsSaveInterface $sourceItemsSaveInterface,
    SourceItemInterfaceFactory $sourceItemInterfaceFactory,
    ObjectManagerInterface $objectManager,
    GetSourceItemsBySku $getSourceItemsBySku,
) {
    $this->sourceItemsSaveInterface = $sourceItemsSaveInterface;
    $this->sourceItemInterfaceFactory = $sourceItemInterfaceFactory;
    $this->objectManager = $objectManager;
    $this->getSourceItemsBySku = $getSourceItemsBySku;
}



/**
 * Updates product quantityn and stock status
 *
 * @param string $sku
 * @param int    $qty
 *
 * @return void
 * @throws \Magento\Framework\Exception\CouldNotSaveException
 * @throws \Magento\Framework\Exception\InputException
 * @throws \Magento\Framework\Validation\ValidationException
 * @throws \Throwable
 */
public function updateProduct(string $sku, int $qty): void
{
        $sourceItems = $this->getSourceItemsBySku->execute($sku);

        foreach ($sourceItems as $item){

            if ($item->getSourceCode() === 'default'){

                $sourceItem = $this->sourceItemInterfaceFactory->create();
                $sourceItem->setSourceCode('default');
                $sourceItem->setSku($sku);
                $sourceItem->setQuantity($qty);
                $sourceItem->setStatus((bool)$qty);
                $this->sourceItemsSaveInterface->execute([$sourceItem]);
                $product = $this->objectManager->get('Magento\Catalog\Model\Product');
                $stockRegistry = $this->objectManager->create('Magento\CatalogInventory\Api\StockRegistryInterface');

                if($product->getIdBySku($sku)) {
                    $stockItem = $stockRegistry->getStockItem($product->getId());
                    $stockItem->setQty($qty);
                    $stockItem->setIsInStock((bool)$qty);
                    $stockRegistry->updateStockItemBySku($sku, $stockItem);
                }

                break;
            }
        }
}

}

I guess your issue might be related to MSI and Reservation functionality

I recommend to review data in inventory_reservation table

Unfortunately, you cannot disable this functionality with configuration, but you can install plugin like https://github.com/AmpersandHQ/magento2-disable-stock-reservation for do this.

If it's a revision logic and you need to set available saleable qty for product you can clear inventory_reservation table data for updating product.
