how to set product attribute value programmatically magento2

Question

I've made a product attribute "inbound" and it has two options, yes and no, I have assigned "no" to it initially but when I'm checking out I'm using an observer to change its value to "yes" programmatically if product quantity less then 100, everything is working fine but can't able to change its value to yes.

Thanks in advance

Here is how you can set attribute value $product = $this->productRepository->getById($productId); $product->setData($attributeCode, $attributeValue); $this->productRepository->save($product);

you are using $this->productRepository->getById($productId); so it means i can use Magento\Catalog\Model\ProductRepository dependency ?? – nihal malik Apr 10 '20 at 12:27
Yes you can set product attribute , by loading product's object and then use set method to set attribute value and then save. – Hamendra Sunthwal Apr 10 '20 at 12:28

hey there, my attribute is multiselect and its adding a new row for the attribute.if a product already has a attribute value selected like "no" if i tried to make it "yes" using your code its working but its not eliminating the "no" it sets both values yes and no for the product – nihal malik Apr 12 '20 at 14:51
is there any posibility to unset no and set yes to the attribute?? – nihal malik Apr 12 '20 at 14:52
i've checked it by making selectbox and multiselect both its adding a new row to attribute which is making a mismatch in data in db.you can refer to this image below. – nihal malik Apr 12 '20 at 15:11

Thanks everyone for the answers, it really helps, i got the right way to do that, rather using setcustomasttribute function cause its throwing errors.you can just simply do this.

$product = $this->productRepository->getById($productId);
$product->setInbound($attributeValue);
$product->setData('store_id', 0);//remember to set store id other wwise data 
mismatch occurs//
$this->productRepository->save($product);
