I've been working for and with SAP for 7 years now and I can definitely recommend to do the step. Though it is a really hard start and it's and world on its own you won't regret it. Finding a job is a problem you will never have to think about and it gives really good money. Almost every big sized company uses SAP nowadays and thus you can either choose to be a consultant or work internally. Unfortunately a lot of SAP products look like they are from the 90s (and technically they are) and it is not as fancy as other technologies. If you are already into web development you could start have a look at UI5 which is the UI for the upcoming products.
