Learning SAP


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
