If you didn't realize you were missing an anchor ASIN until after you uploaded the template and created a new parent you’ll need to search the new parent you created in the Inventory page of Seller Central and delete it, make sure you are deleting the parent, not the child.

Next, we need to create an anchor ASIN. To do this go back to the Variation Wizard and click ‘Sell yours’ on one of the listings already listed under the parent, make sure the condition is set to ‘New’ and add a dummy price or it will become an incomplete listing. 

Remember, dummy prices are only necessary when adding anchors or the listings you're adding to your inventory through an upload when creating new parents. If the listings are already in your inventory it’ll pull the price information from your inventory.

Adding the price will create an out-of-stock listing in your inventory instead of incomplete. You don’t want to add a quantity, because you don’t have any to sell, make sure you leave the quantity blank.

Once you’ve added the anchor listing, add the orphans, check, and upload the template.
