HANA New User Creation - program/procedure/Script

Hi Experts,

In SAP-ABAP-BASIS, The Tcode SU01 is to create a new user. The SU01 will call the program SAPMSUU0. We will get the program details through SE93. We can check the logic by going through the program.

In HANA we can create the new user like below (other way:  CREATE USER.....):

I would like to know the program/procedure/Script which is running behind to create a USER? How to get the details?
