Procedure documentationConfiguring Resources for bgRFC Locate this document in the navigation structure


If you want to use bgRFC functionality, you need to have sufficient system resources in the form of dialog work processes.


To use the bgRFC, the following parameter needs to be defined in the instance profile file (make/<sysid>/profil_gen.txt) or maintained dynamically using transaction RZ11.

  • rdisp/wp_no_dia: Number of dialog work processes 

Note Note

When making this setting, you need to consider the following:

This parameter specifies the maximum number of all dialog work processes.

You can work out the minimum number of work processes that you need for the bgRFC using the following rule of thumb:

End of the note.
  • Inbound processing: Number of schedulers used + 2

  • Outbound processing: Number of schedulers +2

  • Outbound and inbound processing: Total number of schedulers + 4

Note Note

The performance of bgRFC processing does not necessarily depend on the number of schedulers. With a low workload level, it is possible to obtain greater throughput with fewer schedulers.

End of the note.
  • rdisp/autoabaptime: AUTOABAP (sapmssy6); Default 300 s (Minimum 60 s)

Note Note

The value entered here determines the time that elapses before schedulers are restarted. If the AUTOABAP runs every 300s, the scheduler restarts after 300s.

End of the note.

Report RSRZLDG0 can be used to reset AUTOABAP runs that contains errors.
