This SKU does not exist in the Amazon catalog. Your [price, override, inventory, or product] data was not processed. For reasons why, and help fixing this, see http://sellercentral.amazon.de/gp/help/25001
No action can be taken for the SKU you provided because it does not exist in the Amazon catalog. Common reasons why this might be the case include the following:
If you receive this error after submitting a tab-delimited inventory file to update or create a product, there may be other errors associated with this SKU which prevented the SKU from being added to the catalogue successfully. You should check for and correct those errors. Then resubmit your inventory file and this particular error message will disappear.
If you receive this error after submitting a tab-delimited inventory file to delete a product, no corrective action is necessary.
If you receive this error after submitting a tab-delimited shipping overrides file, your override cannot be activated because the SKU you specified does not exist in the Amazon catalog. Errors in a previous inventory file prevented the successful creation of this product. You should first correct errors associated with this SKU in your inventory file before attempting to create a shipping override.
If you receive this error after posting an inventory, pricing or shipping overrides feed (XML), you most likely did not successfully add this product to the Amazon catalog using a product data feed. You should check the processing reports for your product data feeds and correct any errors associated with this SKU. Once you have successfully created the product by posting a product data feed, you can then post your inventory and pricing or shipping overrides feed.
If you receive this error after trying to re-create a deleted SKU, please wait for 24 hours from the time you deleted the SKU before you attempt to re-create the SKU.
