Dear Paddy,
Let me do the same.
As in your technical way, ABAP (Advanced Business Application Programming). SAP is developed in ABAP. Like C++, C, C#, Java, ABAP is also a programming language for SAP.
In SAP, there are three categories: 1. Technical, 2. Functional, 3. Technofunctional.
1. Technical modules include:
a. Basis (like network administrator)
b. ABAP (programmer).
2. Functional modules include:
a. Finance
b. Controlling
c. HR
d. Sales and distribution
e. Material management... and many more modules.
3. Techno-Functional:
a. ABAP HR
b. CRM
c. BI (Business Intelligence)
and many others.
First things first, SAP is already developed ready-to-use software for all countries and all types of businesses.
In HR, a module is already developed. What will you do after completing this course?
1. End-user (only entering data) (similar to an accountant working in Tally).
2. Configuration (customizing as per company or client needs).
SAP HR consultants in IT companies will go to the client's place where SAP is to be implemented and sit with HR personnel from the client company. They understand their needs and customize the module according to the company's requirements. They structure reports and send them to ABAP developers for writing the customization program.
If you are doing the ABAP module, you can customize any modules like MM, Finance, SD, etc., but you cannot do it for HR. As I mentioned in an earlier post, the HR module is more complicated compared to others. It is a very important module. After doing ABAP-HR, you can become a programmer for that specific module. HR is a core area, and ABAP HR is the programming area.
If you want to be in the HR module, you need to understand the core HR area of the company. You must have experience in HR in any company to quickly grasp the HR module and secure a job. I recommend you to go ahead and do ABAP HR since you are already a programmer. Then, you can update yourself with new upcoming modules like e-recruitment (similar to job portals like Naukri, Monster, etc.). SAP always has updates. Try it first, and the rest will follow.
It's more than an ocean.
All the best.
