Case study, consumption issu!

if i have 3 products in the inventory, A, B and C
A has a recipe
B has a recipe including A
C has a recipe including B

when sell product C, inventory consumption will work fine Just it is contain ONLY 1 unit of B. if it is has 2 or more units will consume only 1, and inventory will reduce only for 1 each time.

Any one noted this issue or only me.
i make my own solution by add several lines each line for 1 of B in my recipe.

Can clarify a bit more, post some screenshots of what’s happening?
I probably won’t be able to help you but it will help the people helping you.

A picture can say more than a 1000 words, (i make the same mistake often in this forum, not posting screenshots)
