I think there are 2 types of mentality around people working in SAP. One is doing SAP for the money while the other is doing SAP for the sake of technology/interest of it. I see alot of LYN member wanted to venture in SAP because of the high pay. Bear in mind that in SAP there will be alot of challenge in the coming years. The existing SAP Netweaver technology poses a new challenge even for a seasoned SAPer since new internet technologies been added i.e. XML, SOAP etc

The way forward is to embrace the new technology if you're interested to move with SAP. If not, why not consider to do the things you love to do ? When that is so, money will comes to you naturally with your expertise and passion that you've put into it. Besides, learning things you like is much better than learning for the sake of money.

SAP system is just ordinary SYSTEM... there are many types of SAP SYSTEM (or some call it Solution/Package) but generally we call it R/3 (from those days till now although the proper name now is NetWeaver) for the SYSTEM foundation.

So as per any SYSTEM, SAP System Administrators are just like any other Administrators... for an example, Microsoft Exchange Server Administrator. Administrators normally do those routine jobs like maintenance, backup, upgrade, patching, and once in awhile, involve in implementation.
