What this does
Turn this on if you want to manage stock separately for different Shopify locations, warehouses, shops, or stock areas.
When to use it
Use this if stock from different warehouses should update different locations in Shopify.
For example, one warehouse can update your main Shopify location, while another warehouse can update a separate store or stock location.
When to leave it off
Leave this turned off if you do not need separate stock per location.
In that case, the system will combine stock from all warehouses and import one total quantity into Shopify.
