Sap Cua configuration issue [pertaining to logical systems]

Former Member
0 Kudos

Hi all ,

I am performing a CUA configuration.

Following are the systems :

  • System ABC with client 123 (central)
  • System PQR with client 456 (child)
  • System XYZ with client 789 (child)    



I have logged into all the 3 systems individually(with user SAP*) and created an admin user [CUA_ADM] [ SAP_ALL and SAP_NEW]

Next we come to the specification of the logical systems using BD54 or SALE

ABCCLNT123

PQRCLNT456

XYZCLNT789

As per my understanding this is how the process flow should work:

1.ABC


I login to the ABC system (client 123) using the CUA_ADM user and specify the logical systems

ABCCLNT123

PQRCLNT456

XYZCLNT789

All three i.e., 1 central + 2 child

2.PQR


I login to the PQR system (client 456) using the CUA_ADM user and specify the logical systems

ABCCLNT123

PQRCLNT456

XYZCLNT789

All three i.e., 1 central + 2 child

3.XYZ


I login to the XYZ system (client 789) using the CUA_ADM user and specify the logical systems

ABCCLNT123

PQRCLNT456

XYZCLNT789

All three i.e., 1 central + 2 child

Is the approach/logic correct ??

That is do i have to specify the logical systems of both the central and 2 child systems in each of the three given systems ?

Kindly help

Hello Abhishek,

You should have administration authorization on all clients when you are configuring CUA.

But CUA users (that are used in RFCs) don't need SAP_ALL auhts. They can be system type users and there are speciala roles for them.


You can check your configuration and follow below links.

Central User Administration(CUA) configuration - Basis Corner - SCN Wiki



These are my notes. They may help.


Central System

  BD54

     METCLNT100

     METCLNT001

     MSTCLNT001

  SU01

     CUA_MET (System)

        ZSAP_BC_USR_CUA_CENTRAL

        ZSAP_BC_USR_CUA_CENTRAL_BDIST

        ZSAP_BC_USR_CUA_SETUP_CENTRAL

  CUA_MST (System)

        ZSAP_BC_USR_CUA_CENTRAL

        ZSAP_BC_USR_CUA_CENTRAL_BDIST

        ZSAP_BC_USR_CUA_SETUP_CENTRAL

  RFC

     METCLNT100   CUA_MET

     METCLNT001   CUA_MET_001

     MSTCLNT001   CUA_MST_001

CHILD 1 MET 001

  BD54

     METCLNT100

     METCLNT001

     MSTCLNT001

 

  SU01

     CUA_MET_001 (System)

        ZSAP_BC_USR_CUA_CLIENT

        ZSAP_BC_USR_CUA_SETUP_CLIENT

  SM59

     METCLNT100   CUA_MET

CHILD 2 MET 001

  BD54

     METCLNT100

     METCLNT001

     MSTCLNT001

  SU01

     CUA_MST_001 (System)

        ZSAP_BC_USR_CUA_CLIENT

Hi Yuksel,

Thanks a lot for your reply.

Understood most of it.

Have a small confusion :

  SU01

     CUA_MET (System)

        ZSAP_BC_USR_CUA_CENTRAL

        ZSAP_BC_USR_CUA_CENTRAL_BDIST

        ZSAP_BC_USR_CUA_SETUP_CENTRAL

  CUA_MST (System)

        ZSAP_BC_USR_CUA_CENTRAL

        ZSAP_BC_USR_CUA_CENTRAL_BDIST

        ZSAP_BC_USR_CUA_SETUP_CENTRAL

This is regarding the creation of the system users

MET100 is the central system

MET 001 is the first child

MST001 is the second child

As per my knowledge we should create only one system user in the central system

CUA_MET

What is the need of creating CUA_MST in the central system ??

Thanks,

Abhishek Gupta

Hello Abhishek,


You don't need CUA_MST. CUA_MET is enough.

You can delete that part.

Hi Abhishek,

Central System logical name should exists in all the systems (Central + 2 Child).

Child system logical name should exists in its own as well as Central System.

If your child system will be communicating with each other and transfer data then you have to create their logical system name entry in each other. This can be done later on also by Basis team based one functional team requirement and this should not affect your CUA configuration.

Thanks,
