Set custom default qty when creating new product Magento 2.3

Magento Asked by Vadim Shmyrov on September 9, 2020

I need Quantity field to be filled with custom value when creating new product in admin. I have already tried modificators (haven’t figured out how to set data for new product with modifyData($data) and
this answer seems to be not working anymore.. Is there some way to do so?

Making an observer on event catalog_product_new_action and $observer->getEvent()->getProduct()->setQty(%number%) doesnt work either.

Cheers.

You can create your own modifier pool in your custom extension to achieve this. Following files would do the work.

etc/adminhtml/di.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <virtualType name="MagentoCatalogUiDataProviderProductFormModifierPool">
        <arguments>
            <argument name="modifiers" xsi:type="array">
                <item name="defaultQtyModifier" xsi:type="array">
                    <item name="class" xsi:type="string">VendorModuleUiDataProviderProductFormModifierDefaultQtyModifier</item>
                    <item name="sortOrder" xsi:type="number">200</item>
                </item>
            </argument>
        </arguments>
    </virtualType>
</config>

Ui/DataProvider/Product/Form/Modifier/DefaultQtyModifier.php

<?php

namespace VendorModuleUiDataProviderProductFormModifier;

use MagentoCatalogUiDataProviderProductFormModifierAbstractModifier;
use MagentoCatalogModelLocatorLocatorInterface;

class DefaultQtyModifier extends AbstractModifier
{
    public function __construct(
        LocatorInterface $locator
    ) {
        $this->locator = $locator;
    }

    public function modifyData(array $data)
    {
        $model = $this->locator->getProduct();
        $modelId = $model->getId();

        if (!isset($data[$modelId][self::DATA_SOURCE_DEFAULT]['quantity_and_stock_status']['qty'])) {
            $data[$modelId][self::DATA_SOURCE_DEFAULT]['quantity_and_stock_status']['qty'] = 12;
        }

        return $data;
    }

    public function modifyMeta(array $meta)
    {
        return $meta;
    }
}

Here, instead of 12, you can defined your custom qty number.

Replace Vendor and Module with your original Vendor and Module name.

Hope this helps.
