Good morning! I am assuming the answer is No, questions -- does Customer Center/My Account modules something you can customize/extend if you have only SuiteCommerce (Standard) license? Thanks!

Not sure I quite understand your question, but you can extend any standard module in any version of SC/SCA.

Did you mean, in SuiteCommerce (Standard) say I want to customize or extend My Account modules, example: Purchase History add a new custom column to the list and then the Purchase Details View add say an additional custom item field value, I can still do that? I thought that was the Core source?

Right, but it's still JavaScript, so you can still do it. We just recommend you avoid extending base classes because you may end up creating version locking dependencies

That's interesting, since I have no hands-on customization experience yet for SCS, I was under the impression when NetSuite mentioned the "core" source is locked, I thought the "JavaScript" folder (on each module) is part of the core? What does the core source includes then? Is there an article somewhere that explains this? Thanks for answering my questions! As always I appreciate it.

I would still consider this the best resource I have written on the matter https://developers.suitecommerce.com/get-to-grips-with-the-commerce-extension-framework

got it! thank you so much for the clarification!
