Merchant Integration Platform Processing Error: Add Part Type.

[biketubes]

I am getting an error that states:

"21919303 The item specific Part Type is missing. Add Part Type to this listing, enter a valid value, and then try again."

The spreadsheet that I am uploading includes the "part type", so I'm not sure what is causing the error. Links are screenshots of the error and all the data in the upload file.

You may not be using the right header name for those fields, IIRC they are very specific.  You might get better answers posting on the "Seller Tools" area of the forums: https://community.ebay.com/t5/Seller-Tools/bd-p/tools-apps-db
