Configuring a Connection in sapnwrfc.ini

The PowerCenter Client and the PowerCenter Integration Service use the connection entries defined in the

sapnwrfc.ini

file to connect to SAP. The connection entries that you define in the

sapnwrfc.ini

file will depend on the type of connection that you want to create.

The Designer connects to SAP to import metadata into the repository. The PowerCenter Integration Service connects to SAP to read and write data as an RFC client using the database connection that you create in the Workflow Manager.

Use a DOS editor or Wordpad to configure the

sapnwrfc.ini

file. Notepad can corrupt the file.

To configure a connection entry in the

sapnwrfc.ini

file:
