If you look at online job sites, you will see that the rise in SAP jobs is exponential and that the more SAP jobs are opening up, the lesser the job pool can meet the demands.
Many IT professionals from other disciplines such as web development and network management and administration are now trying to switch to SAP jobs.
But the biggest usual problems that these IT people from other disciplines have is how to break into SAP jobs.
Unlike other IT skills like PHP or Java which can be learned by downloading stuff and reading tutorials on the internet, SAP jobs can hardly be done through self training. I guess this is because you can not just easily download SAP proprietary software. And if you intend to the train, you must deal with sky high cost of training.
The key here is that it is hard to get a head start into a SAP job. If you have the money, then an education on SAP, even if it is very expensive, is a sure investment with good returns. Or you may look hard into companies who accept entry level SAP professionals and offer training. Just be ready for a bond.
