Creating System Users 

Use

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

Prerequisites

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

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.

Procedure in the Central System

...

       1.      Log on to the central system (such as ADM, client 070) with the administration user and choose Tools ® Administration ® User Maintenance ® User (transaction SU01).

       2.      Create the following system users:

¡        System user CUA_ADM that is used by the central system for the user transfer (transaction SCUG) to call the central system.

¡        System users for the RFC destinations that you created in the child systems (such as CUA_PRD_324 and CUA_CRM_800)

       3.      Assign all system users an initial password and the user type Communication (CPIC in older releases).

       4.      Assign the system users for the child systems and the system user CUA_ADM the roles Z_SAP_BC_USR_CUA_SETUP_CENTRAL and Z_SAP_BC_USR_CUA_CENTRAL.

       5.      Save your entries.

Procedure in the Child Systems

       3.      Assign these system users an initial password and the user type Communication (CPIC in older releases).

       4.      Assign the roles Z_SAP_BC_USR_CUA_SETUP_CLIENT and Z_SAP_BC_USR_CUA_CLIENT to these system users.
