API to update supplier mail in hz_contact_points from backend
API to update supplier_Mail in hz_contact_points from backend.
Tried updating the email_address using HZ_CONTACT_POINT_V2PUB.create_contact_point.It is working properly while updating email_address of those suppliers which are already null,but
while updating the email_address of suppliers whose email address is already present,its creating a whole new row with new email id and also displaying the old email_address as a different row.
Please provide an API and the sample script to solve this issue.
