How to Insert/Update KNVK for Contact Person Vendor With FM/BAPI

Hi All,

I want to insert contact person for vendor in KNVK table. what FM/BAPI can create contact person in this table?

Now, I found BAPI_ADDRCONTPART_SAVEREPLICA, with this BAPI, I just can create Person (PRNR) in ADRP but not in KNVK.

If I use this BAPI for update contact person, it just only change in ADRP table, not in KNVK too.

Please help me, how i can solve my problem?

Thanks
