How do we integrate the CRM with SAP R/3? Where do we mention the IP address of SAP R/3 server? What else is required?
The integration of R/3 and CRM is via RFC interface. Define RFC destinations in the system landscape. Mention the RFC destination and connection type (Type 3) in the maintain RFC destinations screen. Mention the target host name and target system number and save as IP address in technical settings in SM59 transactions in both CRM and R/3 systems.
