Learning SAP
SAP Security is part of SAP
Basis module in SAP. Basis module is the system administration piece in SAP.
This cuts across all the modules. This is more to do with SAP Administration
and systems management. To learn SAP Basis or SAP Security the person need not
be a functional consultant or do not need to have any domain experience
Who is Suited for Learning
SAP Security Module
The person who is well
suited for getting into SAP Module is the person who is comfortable with
working on computers mainly using word, excel, internet and email. Mainly be able to comfortably navigate the
screens in any software in the computer. Should be able do simple tasks like
copy paste cut delete etc
Trouble Shooting Skills will
be helpful for Learning SAP
There are some people who
will be arts major but they will be very good in trouble shooting the common
problems in the computer and network. If the computer does not work or not able
to connect to the internet. They will be able to trouble shoot and fix the
problem. Unknowingly they will logically trouble shoot the problem and get to
the solution. This is what is required for learning SAP.
Learning SAP is not a Rocket
Science:
SAP is a prepackaged
solution which has multiple modules. You are not re-engineering or developing new
software. The job of the SAP Consultant is to understand the business
requirement of the particular company and configuring the software as per the company’s
requirement.
Central User Administration also
called SAP CUA
Common Problem:
Let say in your company you
have 4 system (Sandbox, Development, Quality and Production). If the Sandbox, development and Quality
systems have 3 clients each and production has on client. If there is a new
user in the company then you have create his user id 10 times as you have to
individually create users in each system.
Following are the problems
encountered with this approach
Master data like user name,
first name, last name, email etc not matching between clients. It is a time
consuming manual work to create user id 10 times
SAP Central User
Administration (SAP CUA)
With SAP CUA we can select
one client in the Development or Quality system as SAP CUA central client. Then
all the other clients and systems can be hooked to the central client with RFC
connection. With this you will be able to create the user master in the central
client the users will transferred to the child system. So the above scenario
the user can be created once and will be transferred to other nine systems.
Advantages:
SAP CUA helps the client
manage the users from one centralized location and reduces repetitive manual
work
SAP CUA help the Master data
is consistent across all the clients
Disadvantages:
Client copies are difficult
as the SAP CUA setup has to be unhooked and re hooked
If the Central system client
in SAP CUA setup is down then all the users in the SAP CUA child system cannot
be managed
Mass user changes are
difficult to make as it take time and it stresses the infrastructure.
Since there is communication
involved the user creation has to be verified before communicating the
credentials
Future of SAP CUA:
The future for this
technology is not bright as SAP GRC compliant user provisioning and SAP
Identity management is also trying to centralize the user provisioning
process. I think more and more clients
will start using those technologies
Steps for Configuring SAP
CUA
Identify the logical system
for the clients in your landscape
Pick the SAP CUA Central
Client
Make SM59 RFC Connection
between the SAP CUA Central client and SAP CUA Child clients
Define the SAP CUA model
using BD64
Distribute the ALE Profile
and SAP CUA Mode
Define the SAP CUA model
using SCUA
Transfer the users into the
central system using SCUL
Configure the data to be
maintained in SCUM
Complete a text compare and
schedule text compare regularly
Check the SAP CUA Logs logs
and idocs regularly
