Managing Logon Groups

You can group SAP system instances and manage them as logon groups. You can create and delete group entries, remove instances from groups, and delete entire logon groups.

Prerequisites

You have configured Remote Function Call destinations.

For more information, see Configuring Remote Function Call Destinations.
You have created logon groups using transaction SMLG.

For more information, see Configuring Logon Groups.
You are authorized to execute transaction SMLG.

For more information, see Standard Authorization Objects.
You have permission Service,Resource(CriticalCustomOperation).

For more information, see Standard Permissions.

Context

When users log on to a logon group, the message server directs them to the server of this group that has the lightest load.

Each SAP application has different resource requirements. Some applications may therefore require more servers and logon groups. Generally, each logon group should have two servers. If one server is not available, the users are automatically connected to the second server. Servers can be added or removed while the SAP system is running.

Procedure

Choose Operations.
Choose Systems from the tabs.
From the Operations dropdown of the instance, select the operation RFC Manage Logon Groups.
Select existing logon groups and the instances assigned to them, or enter a name for a new logon group.
Optional: Select the Set Note chekbox and enter a note to be displayed in the Description column of the instance.
Choose Execute.
