Service Desk / DSWP settings unknown

I am just starting to configure Service Desk in SM4.0 SP12 using SPRO. Within the transaction DSWP, i am trying to create business partners by clicking on Edit / Create Business Partner i get a popup box saying "DSWP settings unknown". I am not sure how to proceed. Is there any configuration guides available for Service Desk Solution Manager 4.0? I see most articles for Service Desk are pointing towards to Solution Manager 3.2.
