I try set new sku using catalog_product_save_after event, its continuously run this observer, But Not save the sku value.


<event name="catalog_product_save_after">
    <observer name="my_custom_product_save_observer" instance="Vendor\module\Observer\Productsaveafter" />



    namespace Vendor\Module\Observer;

    use Magento\Framework\Event\ObserverInterface;

    class Productsaveafter implements ObserverInterface

        public function execute(\Magento\Framework\Event\Observer $observer)
            $_product = $observer->getProduct();  // you will get product object
            $_sku=$_product->getSku(); // for sku


Suggest Me, Why Its Not saved Sku value in magento 2.


It's because you are using catalog_product_save_after. so on product save you are again saving and again this event called so bottleneck happen. I would suggest to use different event. or Use catalog_product_save_before event and just set the $_product->setSku("testNew1"); and not save $product object.

  • I have used catalog_product_save_before and save $_product->setSku("testNew1"); but SKU is not change after add product from back end side :( – Pratik Patel Dec 19 '18 at 9:48

I stuck in the same situation after spending lot of time when i remove/commented $_product->save(); it works for me.

So for the observer in Magento2 don't need to use $_product->save();
