I have been looking into how to use variants, and to be honest I am confused. The product I am trying to create is for a fashion house with multiple outlets in Nepal, and we need to keep track of the inventory according to style/colour/size, how would one go about doing this using variants of inventory with the material receipt stock option? Thanks 
To learn about creation of variants, check https://frappe.github.io/erpnext/user/videos/learn/item-variant.html
And all the stock transactions will take place against variant item, not against template item.
