Not all my products are showing up on the product update drop-down menu. In reading about this I came across the following:
NOTE: Products will be unavailable to send Updates for if they are set to Send Stored/Generated Codes, or are using Inventory Control, or are using the Send Payment Data to a URL (Payment Variable Information URL) feature. You can send Updates for such a product by temporarily disabling those features in the product's settings, then re-enable them if necessary after sending the Updates.
My products are generally ebooks. Why would I need to have those boxes checked on those products? What's the purpose of :
-- Send Stored/Generated Codes
--Send Payment Data to a URL, etc.
