Configuring a Connection in sapnwrfc.ini

The SAP BW Service uses the connection entries defined in the

sapnwrfc.ini

file to connect to an RFC server program registered at an SAP gateway. You register the SAP BW Service with SAP BW at the SAP gateway. The SAP BW Service is an RFC server and acts as a listener to receive requests from SAP BW to run a PowerCenter workflow.

The PowerCenter Client uses the connection entries defined in the

sapnwrfc.ini

file to connect to a specific SAP application server or to use SAP load balancing. The Designer connects to SAP BW to import metadata into the repository.

Use a DOS editor or Wordpad to configure the

sapnwrfc.ini

file. Notepad can corrupt the file.

To configure an entry in the

sapnwrfc.ini

file:

Open the

sapnwrfc.ini

file.
