2.3.7 Creating the sapnwrfc.ini file prior to SAP BW system custom job execution (Windows)
This setup need be performed only when you are using Windows.
If you plan to use the sapnwrfc.ini file to define an SAP BW system custom job, you must create it in advance at the host where the jbwipsta command is to be executed.
For sapnwrfc.ini file creation, see (1) in 2.3.6 above.
