Gaurav,
The above listed are SAP ERP ECC modules.
They are not SAP HR / HCM Modules.
SAP is an ERP therefore it covers all business areas and applications pertaining to several business functions.
HR / HCM is just one of them.
SAP HR/HCM Modules have close to 15 plus sub-modules
and the major ones are Personnel Administration, Organization Management, Payroll (country version) and Time Management.
Also there is Personnel Development component (module). There are others that I am not listing here.
Now all these have their counter parts in the Portal Versions most commonly implemented as ESS/MSS functionality.
ABAP is the programming Language of SAP in which the modules are enhanced, changed or customized.
BASIS is the systems part of SAP which involves SAP installation and administration the main ERP software.
And plenty more.
Ideally someone with HR background can opt to become a Functional Consultant.
Someone with an Engineering/MCA background ideally becomes BASIS or ABAP technical consultant.
If you like programming you can learn ABAP and become a Techno-Functional consultant since you understand HR.
If you want to Learn SAP you can do a certification course form Genovate or the other Institutes.
You will be spending 4 lakhs as a total investment for 1 month. Yes!
This includes your classroom training for 4 rigorous weeks and then 4 days after the training
you will have your certification exam.
The certification exams for HR are very hard to clear. There is a minimum requirement of passing % required.
Questions are multiple choice and have more than one answer correct within a single Question.(read that again)
Also 60% of those Questions are case-based - meaning only if you have understood your classroom teaching
each week and done exercises only then you will be able to "think" and "choose" the right answers.
If you flunk, you will have two more attempts to appear within 6 months. Each attempt will cost you 30k.
About classroom training. 8 hours each day Mon-Fri. Plus you sit back for 4 hours and complete exercises.
The books for each week are new and are close to 800 pages each.4 books in all.
Now - Take this with a grain of salt.
Even if you clear your certification - if you don't have SAP HR functional experience you will never get a job.
you can wait anywhere from 6 months to 1 year. Institutes lie about placements. The other ones who give you
fake experience can cost you your job.
If you are not an MBA this is okay for you.
But if you are then it's bad as you will have to start out with fresher engineers with the same salary and level.
That is as far as SAP is concerned.
If you want to be a Business Analyst why do you need to get into SAP?
There is no remote connection to that.
For being a BA you have to have your functional knowledge in place.
Mainly the process flows of how a certain function in a business can be modeled
on system level. Once you know that, you must figure out what technology applications
can be developed and integrated that are most suitable for your function.
BA is a skill where you must understand both Business function and Technology
in almost an equal sense.
Hope that clears the cobwebs from your head.
And yes lastly to answer the question which you didn't ask but perhaps you want to ask.
No. SAP salaries are not great for the first 5 years.
Also mobility on projects is very very stressful and it's not as glamorous as an SAP consultant
shows it to be. Initially one ends up on a support project and not an implementation project.
Also the market for SAP HR is polluted with Non HR qualified people who are stuck with what they
have as they know nothing about HR as a business or strategic function.
This results into high Client dis-satisfaction but they are recruited anyways
as they are cheaper than a MBA.
So be clear if you want to be Business analyst or a SAP consultant or you want to work
for a company that has implemented modern day HR technology solutions like Workday,
Peoplesoft etc.
Good Luck.
