Can someone clarify, when it comes to extending commerce web service (OCC), what is the difference between extending using the ycommercewebservices vs. using yoccaddon?
I understand that the addon concept allows you to basically develop within your addon, the files get copied over, and therefore you can upgrade the commerce web services without losing your customizations.
But if I create my own web services extension by using extgen and using ycommercewebservices as the template to create e.g. mycommercewebservices, isn't that the same thing? I am not modifying the original commerce web services in this case either?
Any clarification would be helpful.
