[QUESTION]: Item Group implications

What are the consequences of changing an items “item group” after a while. Both financial and stock wise.

Eg.
I create an item and assign it to the “complete” Item Group. Some unspecified time in the future (1 day or 2 years) later I use a part out of that item on a job. Now the item is “partial” so I change its “item group” FROM “complete” TO “partial”.

What are the consequences of that in ERPNext?
