Hi , Everybody,

scene
1. Out of stock, but the alternative items have stock
2. The item is no longer used, will be substituted by another item

sure , we can use alternative material in bom
1. not use use-up
2. use use-up

yse , scence 2 resule is work fine.
But scence 1, if alternative item have stock, plan purchase order will general a new line with the quantity in SO. why not is the quantity in so - alternative item 's stock quantity ?

BTW, in some scene, alternative items 's quantity is not same with the item 's quantity in bom , how to solve this problem ?
