Amazon: How do I set a manufacturer?

Setting manufacturer as brand in product feed

The manufacturer field, for simplicity is pulled from an attribute ‘brand’ (most cases they are the same). Here’s what you can do to override it.
deleteAttribute manufacturer
setAttributeDefault mfg as "Your Manufacturer"
mapAttribute mfg as manufacturer
setParam localized_name "manufacturer"
