The 8047 Amazon error code is received when the SKU was submitted as a variation Child but matches to an ASIN which is a variation parent.
Generic Amazon error message is shown as below.
The SKU <INSERT> was submitted as a variation Child but matches to ASIN <INSERT>, which is a variation parent. This generally occurs when an incorrect ASIN is provided as the “external product ID.” Please resubmit your product with a product identifier other than the ASIN (e.g., UPC, ISBN, etc.) You can find information on other product identifiers on http://sellercentral.amazon.com/gp/help/200211450. If you intended to list against this ASIN, for a new listing, please resubmit your listing with “Parent” in the “Parentage" field. Or, for a new listing, please first delete your SKU and then recreate your listing with “Parent” in the “Parentage” field. To delete your SKU, follow the instructions on http://sellercentral.amazon.com/gp/help/23191
What it usually means:
The SKU <INSERT> was submitted as part of a multi variant Listing (i.e. a 'child') but Amazon has this product as a 'Parent' (matched to ASIN <INSERT>). Childs SKUs must match Childs and Parents SKUs must match Parents on Amazon - you can't cross match. This generally occurs when an incorrect ASIN is provided as the Product Identifier. Please resubmit your product with a product identifier other than the ASIN (e.g., UPC, ISBN, etc.) or paste in the correct matching ASIN value.
