Creating new user profile with bio data using the service operations SCC_USERREG_CREATEACCT and SCC_

We are trying to create a new user profile (e.g. TEST1) with some bio data (firstname, lastname, DOB, address ...etc) using the web service SCC_USERREG_CREATEACCT and SCC_SUBMITCONST.

1. First, we have run the service opeartion SCC_USERREG_CREATEACCT and it creates successfully a new user profile (e.g. TEST1) and a new SCC_TEMP_ID into the constituent staging table.
2. Later we run the service SCC_SUBMITCONST with the SCC_TEMP_ID, and it created the bio data into the table ps_names. BUT without an EMPLID

The issue:

The issue we are face too is that the user profile is not linked with a new EMPLID. In both the psoperdefn and ps_names tables, the emplid field assoiated with newly created entries is empty.
