2.3.7 Creating the sapnwrfc.ini file prior to SAP 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 system custom job, you must create it in advance at the host where the jr3bjsub command is to be executed.
For sapnwrfc.ini file creation, see (1) in 2.3.6 above.
