Magento: How to synchronize the stock of multiple simple products?

Question

In Magento I have created a configurable product with a couple of associated simple products. I want these simple products to synchronize stock when it changes for one of them.

For example: I have a configurable product: T-shirt. The associated simple products are: T-shirt black, white, red and blue. Each simple product has 1 in stock. When a black T-shirt is bought it will go out of stock, now I want the white t-shirt to synchronize and go out of stock as well.

Is there a way to link certain associated simple products together this way?

Answer 1

if you only update the configurable product quantity,best solution is Go to admin>system>Import/Export>Dataflow - Profiles>Export Product Stocks

Then select only Mapped Fields in Data Format and add these required fields (screen shot below) in Field Mapping section and save and continue,

Then go to Run Profile section in your left hand side and click on Run Profile button.

Connect FTP or download your csv root/var/export/export_product_stocks.csv update product inventory or import Import/Export>Dataflow - Profiles>import Product Stocks

upload your file and same run profile.

your all product's inventory will be updated.

Thanks......
