You can use a user of the type System to perform dialog-free communication between systems; that is, communication by Remote Function Call.


You have performed the preparations in the section Defining Authorizations for System Users.

Note Note

If your systems are already configured for ALE distribution, you do not need to create a new system user, but should use the existing system user. Extend the authorizations of the existing user by assigning the roles specified below to it.
