Azhar Iqbal,
I have some questions on your requirement at the business.
1. Who is your company selling the goods to....Dealer only, or Customer only or both Dealer and Customer
2. If ur company sells both to dealer and customer, for sales orders to customers, the customers will be Sold to Parties. What partner function will Dealers play in that case. I dont think dealer has any role to play there. There is only direct sales buying relationship between your company and the customer and the case is a direct sale, not a sale through the dealer.
Your requirement is applicable only if point 2 is applicable. In this context the agreement will be between only customer and company and dealer plays no part in it. Hence even in business context the functionality does not make any sense.
If dealer uses a separate SAP system for his sales to customers, then he should enable Crdt Mngt in his SAP system. Crdt Mngt shdnt be enabled in the company's system in this case.
Hope this clarifies. Reply if this is incorrect.
