I've been getting this error when uploading using the UIEE file format.

Apparently I need to include a new header.

Anyone know what the header for 'list price with tax is for the UIEE file format?

Advice would be much appreciated.

****** Amazon have decided that the UIEE file format for books is no longer a thing. You are now required to enter a 'list price with tax' field but they will not provide us with the UIEE code needed in the files for this to work.

What are others doing? We cannot be the only bookseller that this has affected surely?

This is what Amazon have told us so far (mind you, some of the support staff still tell us to use the UIEE files!):

"Upon detailed investigation we found that the List Price with Tax field is not a part of the UIEE format/template which you are using to upload your products. So you will not be able to update this attribute value through the UIEE format. It is not possible to include this specific attribute in the template in any way...The only option for you to use a regular/category-specific feed template to update this attribute value for your listings. It cannot be done using the UIEE format, as this feature is not present in that template currently."

Hi guys,

I'm attempting to upload a file for products that are new to Amazon catalogue, under the file type Inventory Files for Specific Categories.

I have filled in the required information, but I get an error message saying 90009 Fatal The file's header row is missing or invalid. The header row is for Amazon use only and must not be modified or deleted. To correct this error, download the template again from seller Help and use that new copy, or insert the correct header row directly above the column headings in your existing file.

I've reuploaded it numerous times as different file types, I've tried contacting Amazon but all to no avail. I've also seen people have had this issue for years but can't find a fix.

Any help would be much appreciated
