Getting Custom Partner Functions from SD to COPA

Although even SAP suggest a method of extending structures, and enhancing user exits, and regenerating function modules to extend Custom partner functions, there is an easy "pure configuration" way.

I simply don't get it. this is now the second time in 1 week that one of my collegues has issues in getting the custom partner functions into COPA.

Custom partner functions are used to set relationships between a sales order (and subsequent documents) and persons or other relational entities.
a partner function can refer to another customer master, and employee master, or a vendor master. This allows you to add for example a external agent in a sales order, who is also a vendor, or a internal sales agent or rep, who is also an employee, or simply another customer who has some kind of relationship with the current customer (sold-to).

SAP recommends applying an OSS note to get this relationship into COPA. But this oss note is in my opinion totally redundant, and complex.

There is now an easier solution, which is pure configuration, to add a custome partner function into copa.
I am planning to create a detailed solution paper about this, in the coming days.
