If your business has multiple locations, this article explains how to add inventory to multiple locations via the Chain Library.
Go to Manager > Chain Library > Product Library.
Next, check the Show branch-created products checkbox in the filters area to ensure you're looking at inventory from all locations in your business.
Check the boxes beside each product you wish to add to another location(s), then select Apply to branches.
Finally, select the locations where you want to add the product, then click Apply to finish.
Choosing a location where the product is already available won’t change the product there. It will stay the same in that location. Likewise, deselecting a location won’t remove the product from that location.
