Hello,
The company that I am working for cloud project want to create business partner with only entering the name, country and company code data. When a business partner transferred through integrastion, I need to fill some general data like adress, tel, email etc. and change the BusinessPartnerType of the business partner. Also I have to create a Customer role (FLCU01) and sales area data of an existing partner.
I cannot use the PATCH operation for creating new role;

When I use create or update operation;
I can add business partners general data, but it overwrite it.
It creates FLCU01 role, but when creating a new sales area data, it gets an error message. On the other hand, we can see these roles at the S4C system.

Thank you,
Best Regards,
Asli
