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.
Here is a small solution we are trying to configure in SAP system. This example will give you high level view of the system administration function in SAP.
Central User Administration also called SAP CUA
Common Problem:
Let say in your company has four (4) systems (Sandbox, Development, Quality and Production). If the Sandbox, development and Quality systems have 3 clients each and production has one client. Then If there is a new user in the company and if he needs access to all the above systems, then you have create his user id 10 times. As you have to individually create users in each system.
Problems with this approach
Since the system administrator is entering the master data like user name, first name, last name, email etc manually in the system there is lot of potential for wrong information being entered. Additionally the system administrator will be doing lot of manual work to complete the task.
In this case we will hook up multiple systems from one central system and manage the user id from one place.
From the above example you can clearly understand that you have understand the business scenario of the problem and apply the solution / tools SAP is providing the customer. As a SAP consultant your job will be to help the client configure and implement the solution.
SAP Career is combination of technical and functional skills. Functional skills need are finance Spending chain and Human resources.
