SAP uses the communications protocol, Remote Function Call (RFC), to communicate with other systems. SAP stores RFC-specific parameters and connection information in a file named
sapnwrfc.ini
.
Configure the
sapnwrfc.ini
file on the PowerCenter Client and SAP BW Service with parameters that enable communication with the SAP BW system. This file enables PowerCenter to connect to the SAP BW system as an RFC client.
The PowerCenter Integration Service does not use the
sapnwrfc.ini
file. When the SAP BW server requests data from PowerCenter, the SAP BW Service records the host name and system number of the SAP BW server. The SAP BW Service passes this information to the PowerCenter Integration Service. The PowerCenter Integration Service uses this information to connect and load data to the same SAP BW server.
