Creating SAP user in SU01, using SAML2 to login with Google

Our company will be rolling out ESS/MSS to our employees. We have activated SAML2 so when a user accesses the Fiori Launchpad, the user will be logging in with their Google account. We would like to avoid having new users be prompted for the first time accessing FLP to change their SAP password since they won't need their SAP password.

We are using BAPI_USER_CREATE1 to create the SAP users.
