CUA(Central User Administration) configuration step by step

  This document will help you to configure CUA in multiple client/systems in your sap landscape.

Preparation:


1.       SAP Landscape/single system with multiple clients
2.       Access to SAP and tcodes SU01, BD54, BD64, SCC4, SCUA, SCUM, SM59
3.       Create system users in central system and child systems
4.       Create RFC connections between systems
5.       Create logical system
6.       Assign logical system to corresponding clients
7.       Create model view
8.       Add BAPI to model view
9.       Generate partner profiles and distribute model view
10.   Create CUA and distribution model
11.   Maintain parameters between central and child systems

All the above steps required to configure CUA in your SAP landscape
In this tutorial we are going to look at CUA between two clients

Let’s see CUA configuration step by step.

 1.       SAP Landscape/single system with multiple clients: 

We have a sap system called EC3 with two clients.
I am going to use 400 as central client and 410 as child client.


2.       Access to SAP and tcodes SU01, BD54, BD64, SCC4, SCUA, SCUM, SM59:
I Have access to SAP system EC3 and all the above tcodes.


3.       Create system users in central system and child systems:

These system users required for RFC configuration between two clients

Client 1:    400
User : CUA_EC400
Client 2:    410
User : CUA_EC410
 
               Above are the usernames created in client 400 and 410 respectively with below roles.

User CUA_EC400 with below roles

SAP_BC_USR_CUA_CENTRAL
SAP_BC_USR_CUA_CENTRAL_BDIST
SAP_BC_USR_CUA_CENTRAL_EXTERN


User CUA_EC410with below roles

SAP_BC_USR_CUA_CLIENT
SAP_BC_USR_CUA_SETUP_CLIENT


4.       Create RFC connections between system:
 
I have created RFC connection between these two clients and is R/3(ABAP) connections.

Please refer  RFC configuration between systems in the earlier post in our blog RFC Connections

5.       Create logical system:

You need to create logical system for each client/ system and make sure it shouldn’t defer from RFC connections respectively
Go to BD54 tcode and setup logical systems.

6.       Assign logical system to corresponding clients:

Go to tcode SCC4 and assign the logical systems to each client/system respectively.


7.       Create model view:
 
Now we are all set to go for model view creation.
Go to tcode BD64 and click change button

And then click create model view button and enter the model  view

Enter a short description and technical name as shown in the below and hit ok button


 8.       Add BAPI to model view:

Select the model view and click “Add BAPI”.


You need to enter model view, sender/client, receiver/server object name/interface and method
As said initially I used 400 client as sender/central system and 410 client as receiver/child systems
Enter the “object name and Method” as per above figure and click ok button.

9.       Generate partner profiles and distribute Model View:
 
We are done with model view creation and BAPI.
Now we need to generate partner profiles go to Environment and click generate partner profiles.

You will get a message saying partner profiles are generated newly if your generating 1st time or you will get a system message like below figure.

Come back to the BD64 screen and select the model view and go to Edit ModelView --> select Distribute
This will distribute your model view to child systems and you will get message like below

So now we are done with model view creation and distribution.

10.   Create CUA and distribution model:

Go to tcode SCUA and create distribution model
Enter the model view name which is created in BD64 earlier and click create button as shown in below figure.

Now you will get a screen like below and select the child systems in the pop up screen


Once you selected the system name and click save.
You will get a screen like below if you are done everything correctly which means your CUA configuration is done successfully.


So we are done with CUA configuration successfully.

11.   Maintain parameter between central  and child systems:

Once we are good with CUA configuration there are parameter setup needs to be done from central system like which all are maintained in central and child systems
Go to SCUM tcode àclick to change mode for parameter maintenance


It will give you broad idea about what are the parameters should be maintained centrally and which can be maintained child system as well as globally.
Ex. Role addition should be done from central system and password reset and  defaults can be maintained from both centrally and local
Please let me know if you have any suggestions and comments so I can improve the future post.

I will post video tutorial on this topic in upcoming days which will help you to learn much more easily.

    1. Thanks for the good explanation. I have couple of doubts in CUA. If the central system is down how would I go ahead with administration and will I also loose access to child systems. I
      2.I've configured CUA in all three systems but want to maintain different validity for users in each system is it possible if so how
