For some "Special" products in a webshop I want to use Backorder stock instead of actual stock which is available for those products but not sure how to proceed with it.
I have looked into
MAGE_CATALOGINVENTORY_STOCK_ITEM and its functions
VerifyQty() but still do not how shall I tell Magento to not use actual stock when I place order for those products. Because I do not want Magento to reduce the stock for them. Also I am not sure if I do it in an event or by overriding
I be very grateful if someone can give me ideas or share some code regarding this.
No, I have not written any code so far as I am not sure how to proceed with it.
