[Grouped product] Can´t add simple products to cart if one other is out of stock

@JadeArtistry 

You no need to create the same file path in app/code folder. Your way will not work. 

Please find the file below folder structure:

\vendor\magento\module-grouped-product\Model\Product\Type\Grouped.php

You can check with change in this file. 

Also I would suggest you to override this code with creating a custom module.

Hi @JadeArtistry 

It's delayed massage. You have created a wrong directory structure.

File code changes are correct but directory structure is wrong

Update code line no. 347

if ($isStrictProcessMode && !$subProduct->getQty() && $subProduct->isSalable()) {

You can update the file code changes on vendor/magento/module_groupedproduct/Model/Product/Type/Grouped.php file for now later update with the creating custom module.
