SAP GTM and FSCM Credit Management

Hi

We are implementing SAP GTM module for trading contract and want to integrate it with FSCM Credit Management. We could not find any direction from SAP and have limited information about. Please suggest any sap note or recommendation and steps which we need to follow. Also what is the difference between SAP SD linkage which we normally have with FSCM credit management. Will all the reports, interface and BADI remain same. Do we need any special seetings in FSCM for GTM integration.
