Fiori App Transport - Standard & Custom Apps

Hi All,

I was looking to understand the Fiori app transport process but was getting more and more confused with each answer I read online. So I wanted to as a few questions.

1. How are standard apps transported across systems? One answer suggests that standard apps are not transported but are installed in each system and I find that quite unusual to what I already know about transport standards.

2.The most widely quoted post is from 2014 and I would like to have a more updated answer to how standard, custom , and enhancements to fiori apps are transported. Will this be a SOLMAN based transport in all cases? Or is there more to it that I am missing?

Thank you for your time.

Regards,

Shyam
