We have configured CVI masterdata synchronization for Customer<->BP and this is working well for customer masters without contact persons.
However, when we try to add a contact person to an existing customer (or synchronize an existing Customer with contact persons) we get the error message R1201 "Business partner ### does not exist".
I have checked the wiki.
We are able to manually create a Person with role BUP001 (Contact Person) and link it to the BP with relationship cat TBUR001 (Is Contact Person For). Here the synchronization BP->Customer seems to be working, as the new contact person is successfully created in the Customer.
Any ideas why we cannot synchronize Contact Persons, Customer->BP?
Thanks in advance,
