Item Variants in Dynamics NAV

Question

I never used Item Variants in Dynamics NAV. I read, this is useful if I have a large number of almost identical items that vary only in somewhat.
I have production of metal parts and we paint themin different colors. This could significantly reduce the number of items we use.
But, I cannot find how I can create different BOMs per different variants. I see, I can put variants in BOM components, but not in header.

Answer 1

You can use item variants for goods, but BOM is one per one item. Does not matter how variants you have per item, one item can has only one BOM. You can make more BOM versions, but not connect them with item variants.

Answer 2

So how to use varians for goods? I will have the same components in BOM for all variants, but paint will be in different variants.

Answer 3

You can make one BOM per item and do not put variant for item color in BOM line. When you have to post consumption, you will manual choose variant for different color. You can do it only that way.
If you want BOM per variants, you have to make complex customization. BOM is not used only for posting journal.
