The error your getting is saying that it cant find the product codes which suggests that your P2 Product list may not be populated correctly. Can you verify that your P2 Products list looks like this? If it doesn't try reloading this list first. Because there is a parent / child relationship, you may have to populate all the product lists starting at P1 and work your way down. Top to Bottom. Once you're sure you've got the product list loaded, then try importing to your SYS06.
