Magento 2 - Unset Special Price programmatically

Question

I have an import script which imports configs and the variants.

There is set the special price if some is set in my import XML document. If no special price is set, i try to remove the special price. - But it do not work! - The special price is already set, after save!

if ($oProductGroupVariantProductItem->getSpecialpriceBrutto() > 0) {
    $oSimpleProduct->setSpecialPrice($oProductGroupVariantProductItem->getSpecialpriceBrutto());
} else {
    $oSimpleProduct->setSpecialPrice('');
}

what i am doing wrong?

Thanks Andre

Answer 1

Saving the price and forcibly update the product attribute using the resource model worked in my situtation:

$product->setSpecialPrice(null);
$product->getResource()->saveAttribute($product, 'special_price');

Note: Make sure a $product object has store_id = 0. special_price attribute is global attribute. If store_id won't be 0, this method won't work, then you will try to unset special_price.

Answer 2

You just need to save the product after you updated the attributes.

Try this:

$oSimpleProduct->save();
