When you set up synchronization for the first time, the system connection properties are set to default values that you can modify. There are two ways to do this:
Specify a specialized variable set and change the values of the affected variables.
The default values remain untouched in the default variable set. The variables can be reset to the default values at any time. (Recommended action).
Edit the target system connection with the system connection wizard and change the effected values.
The system connection wizard supplies additional explanations of the settings. The default values can only be restored under particular conditions.
