Can any one tell me where I can find the link between business partner and the role 00000 General, or the link between contact partner and the role BUP001?
Are you talking about the roles in CRM versus the roles in IS-U? If that's your question then the BP role Sold-to party in CRM is mapped with the BP role contract partner in IS-U. There is a tridimensional relation between the BP CRM (Sold-To Party) , BP IS-U (Contract partner) and SD customer.
I hope this clarifies your question.
