Question about variations

I have listed 5 variations in 1 product. I have sold out 1 variation. I tried to order another shipment but supplier response took very long. So I changed the supplier and ordered sample product.

  1. How long the listing can be out of stock?

  2. Will it affect my ranking?

  3. I have created 7 variant. 2 variants are still inactive as I didn’t ship for those variant. Can I activate those variant or do I need to create new listing?

If only one variation is out of stock, ranking should not be affected to much. You can keep it out of stock as long as you need.

The other inactive variation can be activated when you will be ready to replenish.
