Replication of new employee data with old characteristics

Hi Experts,

We need your help regarding the following concerns,

There are some employee data in existing sap system and new range of employee data will be created.

Now, users wants to copy all the  Info type from old employee to new employee.

Is there any standard FM to do the same ? We found one FM called 'HRUS_COPY_EMPLOYEE_BASIC' to copy the employee

but it gave dump while we tried with one employee.

Can you please give us any inputs regarding the options for fulfilling the same ?

New to HR so does not have much idea.

Waiting for your valuable inputs.

Thanks in advance.
