replacement of API ap_vendor_pub_pkg.update_vendor_contact in EBS R12

Hi Folks,

We are having a supplier management system developing on OAF with instance R12.1.3.

The contact person detail under the supplier site need to be updated. Only the first name, last name and inactive date are using in our business context. I called pl/sql procedure ap_vendor_pub_pkg.update_vendor_contact, passing the first name, last name and inactive date and run it. Only the inactive date was updated. This API ignore all other information we passed to it.

Can anyone tell me what new API is using to update the supplier contact? I tried the hz_party_contact_v2pub, there are no column in parameter p_org_contact_rec in this API can be used to update the first name or the last name.
