FM to get supervisor information?

I know the pa and hrp tables where this information is stored. But what i am looking for is a FM or BAPI where i enter an employee pernr and it returns me its supervisor pernr and other supervisor personal data such as First, Last Name and email.

If i can get supervisor pernr from the FM is also great. Because then i know an other FM which can be used to get supervisor's personal data.

Thanks
