Bapi_Bupa_Central_Getdetail not returning the phone numbers

Hi,

When i pass the business partner number to Bapi_Bupa_Central_Getdetail i get back the basic information like name, date of birth etc but i dont get the address, phone numbers and email values. Other than the business partner number have i got to fill any other value in the parameters being passed to fetch the phone number and email information.

Regards,
