Use the following procedures to create or maintain RFC destinations.
When maintaining the destination information, consider the following options:
In this section, enter the connection information to the ABAP server. If you use load balancing, then enter the system ID, message server and the logon group to use for the connection. Otherwise, enter the hostname and the system number.
Enter the gateway hostname and service to use if the destination is a registered RFC program.
To secure the RFC connection, you can use SNC. In this section, maintain the SNC parameters.
Either enter a predefined service user or select to use the current user. For the current user, you can specify that either the user's logon ticket or an assertion ticket should be used for the authentication.
If you use a service user, then make sure that this user only has those authorizations in the ABAP system that are necessary to perform the desired task.
If the user used for the connection does not have the authorizations to access the ABAP repository, then you need to set up a destination to use for this purpose. The repository destination should then access the ABAP system with a service user that has the appropriate authorizations.
You can then select the repository destination as the access method to use to access the repository instead of the user specified for the current RFC destination.
Creating a Destination
The available destinations appear in the Destinations List. If you select a destination, its details are shown in the lower pane.
The General Data screen appears.
The Connection and Transport Security Settings screen appears.
The Logon Data screen appears.
The Specific Settings screen appears.
If a destination in the destination service is configured as current user (logon or assertion ticket), the pool settings refer to a single user. Consequently, we recommended setting the values for the number of connections as low as possible.
For example, if the maximum is set to 5 and there are 100 users active on a portal, a maximum of 500 connections can be created.
To activate the RFC trace, set the corresponding indicator in the Advanced Settings.
To maintain a destination, select the entry in the Destinations List. Modify the parameters as necessary and save the data.
