Hi All, I have Installed 2019.2 version source bundles. I'm able to see two SSP applications one is like SuiteCommerce Advanced - Src 2019.2 and other one is SuiteCommerce Advanced - Src 2019.2 SS2. what exactly SS2 mean? I have gone through the dev articles and there it saying that we can use suitescript 2.0 version by using SS2. Is it mandatory to deploy SS2 application along with SCA module?

It is mandatory yes for some features to work. For example if you are using SuiteTax. As @PabloZ mentioned, Cases services has also been migrated to SS2.X so if you don´t deploy the SSP2 it won´t work.

Thanks @Flo. I can see that same case and orderhistory suitescript modules are also available in 1.0 version.
