  • dispatcher, updater
Default Values (Factory Settings)

The predefined default values are:

Instance Type Value

You can use a default value to reset the runtime value or the restart value (persistent) in the Admin+ user interface.

Note

A default value is part of the factory settings of the SAP CC Core Server systems. It differs from the original value set during the installation or after the Customizing activities.

In Admin+, you can reset a parameter value to this default value, but it is not recommended:

  • This value may differ from the original value set during the installation of your SAP CC system.
  • Note that it may also differ from the value defined by the implementation project team and set during the Implementation Phase of the integration project.
Verify the values in your running SAP CC systems before to use the reset command.
