Pros
Extremely flexible. You have the freedom to work from home, and hours can be flexible as long as you are completing your work and participating with the team. Very laid back and informal atmosphere. The team is full of smart, hard working people, and there are a lot of opportunities to learn new things. Everyone is happy to help and communicates often. The office is fun, and there is occasional catered lunch and beer on Fridays. You will make many friends. SAP is a huge company, and there are tons of opportunities to connect with people around the world.
Cons
Workloads have gotten absurd in recent years. Software is buggy and engineering is focused on developing new features instead of fixing issues, putting support into impossible positions. In essence, you are set up for failure day after day. There are very little opportunities for career development within the support organization, and the opportunities that are there are not advertised to the team. The only way for you to get a worthwhile raise is to get a different job within the company, and to leave support altogether. Management is in constant flux, so you never have the opportunity to work with anyone to develop your career in any meaningful way. You get harassed on a daily basis for updates by other internal teams, and more effort has been put to hire people to micromanage you than to ease the workload.
