How to programmatically create source and assign to stock in Magento2

What is MSI – Magento2 Multi Source Inventory (MSI) is newly introduced in Magento 2.3 version(upcoming release) which is used to manage inventory by source (location).

You can get the Magento 2.3 Multi-Source Inventory (MSI) version from https://github.com/magento-engcom/msi.

MSI is a considerable improvement to the Magento core, which connects multiple inventory sources to your e-commerce website.

You can assign multiple sources and sales channels to one stock. But keep in mind, that one sales channel can be connected to one stock only. In this context, a sales channel is actually your Magento website.

Here I’ll show you How to programmatically create a source and assign it to stock in Magento2.

I have created a method InventorySource in the following Helper class file.

You can add this method to your required class file and call on the needed places in your code.
