BAPI_USER_CHANGE under CUA environment

[SAPSupport]

Hello SAP

We are trying to change user password by FM( BAPI_USER_CHANGE ).  Our SAP system is running on CUA environment. We have checked restrictions of this FM under CUA.  No special restriction were found. 

I thought changing initial password will lead changing password of users on child system. Changing anohter item like first name & last name will lead to changing those of user on child system. However nothing happened as we expected. So we didn't specified target child system.

Why anything happen ? Is ther any restriction for Functional Module under CUA environment ?

Dear customer!

Please use the function module BAPI_USER_CLONE instead of BAPI_USER_CHANGE.
There are a few user BAPIs which are explicitly for the CUA usage.
You can check all our user BAPIs in transaction BAPI -> Basis Components -> Security -> USER
