Setting-up CUA for Systems with different Releases

As setting up the distribution model in the simplified form with transaction SCUA is only suitable for Release 4.6C systems, the complete Central User Administration setup procedure is described below.

Perform the following activities:

Create system users
Name logical systems
Assign logical systems to clients
Define target systems for RFC calls

See Setting up Central User Administration.

Proceed as follows:

Define the system environment in the SAP Reference IMG under Basis ® Distribution (ALE) ® Model and implement Business processes ® Maintain Distribution Model (Transaction BD64).

The distribution model is used to specify which applications communicate with each other in your distributed systems. The distribution model contains all of your company’s cross–system message flow information. The distribution model consists of several model views. In each model view, you can define related message flows. Each model view is maintained in a central system and distributed from there to the other systems.

For each model view, you can specify a descriptive short text, the validity period of the message flows in the view, as well as the view maintenance system. When a model view is created, the system in which the view is created is automatically specified as the maintenance system. If possible, designate one system as the central maintenance system for all model views. The names of the model views must be unique in the entire distributed environment within your company.

Do the following:

Choose Create Model view and enter a name and a short description.

Create a BAPI for the object User and the method Clone (Create user with reference from other systems). Use F4 help for possible objects and methods. Also specify which system is the sending system and which is the target system.

Create a second BAPI for the object UserCompany and the method Clone. This method is used for company address distribution.

Distribute the system landscape by choosing Edit ® Model view ® Distribute. The system displays a dialog box in which the systems relevant for you are already selected. Normally, you can just confirm the selections.

In Transaction BD64, generate the partner profiles for all dependent systems (choose Goto ® Partner profile Generate).

For information about partner profiles, see the IMG documentation (Cross-Application Components ® Distribution (ALE) ® Communication)

Generate the partner profiles in all dependent systems for the central system.

Define the system landscape for central user administration in the Reference IMG under Basis ® Distribution (ALE) ® Configure predefined ALE Business Processes ® Cross-application Business Processes ® Central User Administration® Select Model View for Central User Administration (transaction SCUA). Use the F4 help (possible entries) to choose the distribution model you require and then choose Save. When you save the distribution landscape, the information is automatically distributed to the dependent systems.

The Central user Administration is only completely available in from Release 4.6A. Some functions are restricted in previous Releases.

After installing Central User Administration, you must check another system setting with the transaction WE20 as follows, if you use the Workplace Server:

Go to transaction WE20.
Display the subnodes of Partner type LS in the tree structure.
Choose a system in the tree structure.
Double-click on the entry USERCLONE in the table Export parameter.
Change the entry basis type to USERCLONE01 in the IDOC type group.
Save your changes.
Do the same for the other R/3 components in the Workplace.
