Here are the most common reasons a SKU is not found in Manage Listings.
1. The SKU is inactive or the alternative market SKU
The Manage Listings page can be searched using a product SKU, title, tag or identifier. However, searching by the alternative market listing will not return results.
It's not unusual for the SKU assigned to the Product in Listing Mirror to be different from the SKU associated with the listing on the marketplace.
For example, when listings are Linked in Listing Mirror, they are connected to a single SKU to ensure accurate inventory tracking; however, the SKU used on the marketplace remains unchanged.
You can search by market SKU or for an inactive listing, by going to Listing > select the marketplace from the menu > search for the SKU.
2. The SKU is a duplicate
Duplicate listings happen when 2 or more SKUs are assigned to the same ASIN. For example, you sell an item that is both Fulfilled by Amazon (FBA) and Fulfilled by Merchant (FBM). Although the ASIN is the same, the SKUs will be different.

3. The SKU is a brand new listing on Amazon
Listing Mirror syncs with Amazon several times throughout the day. When new listings are added in Seller Central, it can take some time for those listings to be processed and populated in your Listing Mirror account.
4. The SKU is inactive on Amazon or doesn't have available quantities
Listing Mirror automatically imports listings that are active on Amazon with available quantities. Once a quantity has been added in Seller Central, it will be imported into your Listing Mirror account.

5. The SKU is hidden
