Should you really need to learn any module in SAP?
The reason I ask you is that, you seem to have no clue what you want. Looks like somebody is forcing you to get into SAP and you are just playing along. Unless you really know what you want to do, there's no point in going further. And once you figure out what it is that you really want to achieve, you'll figure out which module to take up.
I suggest you start reading about ERP and then about SAP. Get a basic idea of what SAP is all about and what are the major modules in SAP. Then select a module that best suits your domain experience and your interest. Once you've zeroed in on the right modules, start making enquiries if the job market is good for that module. If there's a good demand for those Consultants in the market, then plan to take up a course.
Here depending on your financial situation you need to decide if you can afford a SAP Certified training course or not. After completing the course start marketting yourself in the market using all the jobsites and professional networks untill you land yourself a job. This is the toughest part.
There are numerous threads and blogs with the same objective as yours. Read through them to get an idea.
