Product ID and ID type on upload for Amazon

I've been using CA for a couple of months on ebay now, and am about to move our Amazon listings over. The only part of the template I'm struggling with (so far...) is the product ID / ID type. In my current listing, I have the easy separate columns for ean / upc. . How can I tell the Amazon OOC template to use EAN (and set the type accordingly) where it has an EAN value, and similarly UPC when it has UPC?

Also, I've seen advice saying steer clear of using ASINs - is this correct, that even Amazon don't recommend matching on them?

RE: Product ID and ID type on upload for Amazon

The product ID field is where you would map your EAN, the product ID type field will contain the value "EAN" to associate that the values sent in the product ID field are EANs. 

What it sounds like you are trying to do is send EAN for some products and UPC for others (and ASIN potentially for others).  Since this likely requires you to map two different fields and values you will likely want to use a business rule to say something like "if my product has an EAN in the EAN field send that, if not look at the UPC field and send that, and if not that do...", and a similar rule for the ID type field to provide the appropriate value - EAN, UPC, ASIN - to connect to the ID sent.  We have documented some common rules that do this exact process on this SSC Strategy page.

As for using or avoiding ASINs.  This is a tricky subject - Amazon suggests steering away from this but there are times even they suggest you to use it :) Basically the short answer is that if you submit an ASIN no other information about your product is considered in the listing process and if/when Amazon ever moves or deprecates the ASIN you are using your products will not list (or be listed against incorrect products) and potentially cause problems.  I have seen cases where a seller is listing a pack of 3 golf balls and ASIN matches to the existing product for 3 golf balls but then other sellers come on and that pack of 3 changes to a pack of 6 and now their 3 pack is on a page for a 6 pack and buyers think their price is so much better that they buy it but then get upset when the product arrives and has 3 fewer golf balls than they were expecting so a refund/A-to-z claim ensues and the seller ends up in hot water with Amazon.  Now the only time I have heard Amazon recommend this practice is when the product you are listing continues to error in the listing process over and over (and you have already tried everything to adjust your data and filed TAM tickets and asked for the ASINs to be cleaned up and all that) - in that very rare scenario ASIN-forced matching is the only option to get it listed.
