Required Item Specifics are missing

The error indicates that your products are missing one or more Item Specifics required by the category. 

They may include brand, size, length, width, height, type, color, or style, and vary depending on what you are selling. Item specifics requirements apply to all new and revised listings, so you have to provide valid values for all mandatory Specifics.

Watch a video for Magento 1 or Magento 2 on how to update marketplaces and add missing Item Specifics.

It takes several steps to fix such type of an issue:

1. First is the upgrade of your M2E Pro. See our article about the upgrade to find the most convenient method for you Magento 1 and Magento 2.

2. After you upgrade your M2E Pro, you will need to go to eBay > Configuration > Marketplaces and click Update for marketplaces used in Listings.

3. Navigate to eBay > Configuration > Categories and click View next to the category that the affected products are listed in. You will see an asterisk sign next to those Item Specifics that have to be provided.

4. Alternatively, you may go to the Listing, switch the view mode to Settings, and select Edit Category Settings in the Actions drop-down for the affected products

Please remember to Save the changes after edits to the Item Specifics settings are made.  

Periodically, eBay adds new required Item Specifics based on buyers’ search trends. As a seller, you have to be prepared to specify more data about your products when new requirements are rolled out.
