Error message

The item specific Herstellernummer is missing. Add Herstellernummer to this listing, enter a valid value, and then try again.

What this error means

eBay requires mandatory manufacturer information, specifically Hersteller (Manufacturer) and Herstellernummer (Manufacturer Part Number), for products listed in certain categories. This error means your product feed is currently missing this required data.

How to find and fix the error:

1. Verify the category: Double-check that your product is assigned to the correct category in Lengow. Proper categorization ensures the product inherits the correct attribute requirements.

2. Map the missing values: Go to the Attributes Mapping step for eBay. Locate the Hersteller and Herstellernummer fields for your category, and map them to the corresponding manufacturer data from your product catalog.

3. Push the update: Once the attributes are successfully mapped, perform a push to send the updated values directly to the marketplace.
