2.2.7 Creating the sapnwrfc.ini file prior to R/3 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 R/3 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 2.2.6 above.
