Aura's Dashboard will display a yellow Missing Costs notification if any sale logged in that timeframe occurred with a Buy/Additional Cost having not yet been saved.
As a result, Aura will still pull in the sales' revenue from Seller Central, and will deduct fees, but will not know the Buy Costs or Additional Costs. Therefore, any profit calculated from a SKU with a missing cost will appear as if there was a 0.00 total cost, being unknown.
To check for listings without costs saved, add a Listing alert filter from the Listings page.
Select No cost, and click Save.
You may also filter the listings from Active (set by default) to All, to include inactive and out of stock SKUs that are also missing either Buy Costs or Additional Costs.
The Listings table will then only show SKUs that have no Buy Cost or Additional Cost saved, which would result in the yellow Dashboard error if a sale is logged for any SKU.
Once all SKUs have Buy/Additional Costs saved, Aura will apply all newly-saved costs to logged sales, and the Dashboard notification will self-correct.
