When adding new or revising existing Amazon listings, an error or a warning message can be returned by Amazon. Unlike the warning message, an error will prevent your listing from being created or revised.


Linnworks has no control over these error messages and simply displays the errors that channel send us. Most such errors are self-explanatory.


Here are some error examples and their solutions:


1. The SKU data provided conflicts with the Amazon catalog.

Error: SKU: XXXX-XXXX-SM. The SKU data provided conflicts with the Amazon catalog. The standard_product_id value(s) provided correspond to the ASIN BXXXXXXXXXB, but some information contradicts with the Amazon catalog. The following are the attribute value(s) that are conflicting: size (Merchant: 'S/M (UK 8-10)' / Amazon: '5 UK / 38 EU'). If your product is this ASIN, then modify your data to reflect the Amazon catalog values. Else, check your value(s) for standard_product_id are correct.


The error comes straight from Amazon and it is stated that the information that is entered for this item contradicts the Amazon catalog.

In this case conflicting information is size (Merchant: 'S/M (UK 8-10)' / Amazon: '5 UK / 38 EU').

You will either need to amend those attribute values and update your listing or proceed by matching your listing and adding it to Catalog.


There can be other conflicting attribute values, this error is the example but the idea is the same. You will need either match your values to existing listings, either add it to catalog.


2. Status: Errors while updating

Error: Requested value 'PT9' was not found.


This error means that the item you are trying to list has more than 8 images. Amazon does not allow listings to include more than 8 images. Please check your listing template and make sure that you do not have more than 8 images. If so, then simply change some of your images from "Other" to "None" status and the listing should be successfully created.


3. SKU XXXXXXXXX-Black, Missing Attributes standard_product_id. SKU XXXXXXXXX-Black doesn't match any ASINs. Make sure that all standard product ids (such as UPC, ISBN, EAN, or JAN codes) are correct. To create a new ASIN, include the following attributes: standard_product_id. Feed ID: 0. For more troubleshooting help, see http://sellercentral.amazon.co.uk/gp/errorcode/200692370

SKU: XXXXXXXXX-Black


This error indicates that you would need a barcode value (EAB, UPC etc.) Otherwise, Amazon won't allow for this item to go through.

As a workaround, if you do not have the right barcode you can use the option 'Add to catalog'.


4. Status: Errors while creating

Error: The Message/Product/DescriptionData/Description field contains an invalid value.


This error message normally indicates which value is in question. Please check product_description field and provide a valid value for the field, then try listing again.

5. “Your seller account is not approved to offer seller-fulfilled products in this category at this time”

If you are allowed to create FBA listings only (not FBM) you may get this error while trying to create FBA listing. The problem is that the system does not submit information simultaneously but in batches. The first envelope submits the listing information (SKUs, barcodes, etc.), the second batch submits the Fulfillment Center parameters (AMAZON_EU). When we make the first call (with the first envelope), Amazon returns an error message (Your seller account is not approved to offer seller-fulfilled products in this category at this time)  which prevents us from submitting the second batch (the one that contains the FBA information). 


There are 2 options:


1) This error indicates that you are not allowed to create FBM listings, please ask Amazon to remove this restriction. In this case, FBA listing will be created and no error returned.

2) You can try submitting your items via Catalog.
