Item Variants common question

Hi,

i wondering what the use of item variants…
its jst for information or is there some thing will happends when i set the item variants ?..

i really confused about how item variants works or do

Thanks

If you check Has Variants under Item Master then you can define the variants of the item by generating combinations of its attribute values e.g. color, size, etc. Before that, just make sure all attribute values are properly set under attribute master.

I think we cannot select parent-item when doing transactions, but its
variants. Also stock is maintained on variant level. Have you tried this?

i think i understand now…its just i think i need to create attibute generator… so di dont need to add the attribute one by one
