Configurable Product (package size eg. 1kg, 2kg) how to decrease stock according to that?

[patrick_tschumi]

Hello 

I sell food which I have in stock in let's say 200kg. Now the customer can buy 1kg, 2kg, 5kg, 10kg. It's the same food just in different package sizes. (But they are not pre-packed, they are packed in the right size as soon as someone orders)

Therefore I created a configurable product based on the XY kilogramms (kg). Now I would like my shop to decrease the stock on the main product (which represents the total in kilogramms as qty) in the by it's package size (eg. 1, 2, 5 or 10)...

I hope it's understandable what I mean. If not, please ask.

How can I achieve that?

Hello @patrick_tschumi 

Magento provides decimal qty.

https://stackoverflow.com/questions/16966354/magento-decimal-quantity-stock-management 

I thought you should transfer your configurable product to a simple product and allow decimal qty as well.

Create one attribute for this type of product like consider qty as weight.

By decimal, qty customers can buy your product like 1.5 qty ( 1.5 kg ).

By using a new attribute you can change the label to Enter weight on product page near qty box.

So you no need to manage different stock you can create a packet according to customer order.

It will also help you with shipping charges.

Hi @Hiren_K_Patel 

That's also a good idea but not exactly what I want. I found a module which is doing what I want + some extras, but unfortunatly I get errors...

Fatal error: Uncaught Error: Cannot instantiate interface Aitoc\ProductUnitsAndQuantities\Api\RealProductPuqConfigRepositoryInterface in public_html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php:121 Stack trace: #0 /public_html/vendor/magento/framework/ObjectManager/Factory/Compiled.php(108): Magento\Framework\ObjectManager\Factory\AbstractFactory->createObject('Aitoc\\ProductUn...', Array) #1 /public_html/vendor/magento/framework/ObjectManager/Factory/Compiled.php(150): Magento\Framework\ObjectManager\Factory\Compiled->create('Aitoc\\ProductUn...') #2 /public_html/vendor/magento/framework/ObjectManager/Factory/Compiled.php(79): Magento\Framework\ObjectManager\Factory\Compiled->get('Aitoc\\ProductUn...') #3 /public_html/vendor/magento/framework/ObjectManager/Factory/Compiled.php(150): Magento\Framework\ObjectManager\Factory\Compiled->create('Aitoc\\ProductUn...') #4 /public_html/vendor/magento/framework/ObjectManager/ in /public_html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 121

Has anybody an idea why this is happening?
