You have to mentally prepared for a rough ride .... Don't kid yourself, age discrimination exists every where these days. Even if you are fully qualified for a position, the employer would prefer a much less qualified and younger applicant because you will not "fit in" with the company's culture. I have personally encountered this situation many times, especially with some of the startups.
Also, be prepared to accept a significant cut of your current salary. If you've been with SAP for a good number of years, your based salary + bonus + other perks should be pretty good. Don't be too shock if you have to take a 30% or more cut - that's how it is out in the real world. Unless you can score yourself a contractor gig and you can ask for a decent hourly rate. BTW, don't forget that there is a 2-year restriction at SAP once you are laid off (you cannot come back as a FTE or contractor). If you have the right skills, working for a partner is another option.
Some folks have the luxury of getting more education and training which is great but many folks don't - they have to get a job immediately to pay for their mortgage and support the family now. If you are currently still employed, get yourself organized and prepare an exit plan - you will need one.
I wish everyone that is in the same boat best of luck!! Stay positive, watch your health and take good care of yourself.
