<现在每当别人向萝卜特抱怨IDE不称心开发枯燥郁郁寡欢的时候 我都会……>

告诉他们如果需要处理的业务逻辑再复杂一点，再复杂一点
那相应的Technology会演变发展为需要无尽的时间才能精通，没有精力也不应尝试广泛涉猎

There is no hard and fast rule that you should know everything in this world. It is unlikely and not possible, especially in SAP no one is assumed to know everything.

You should document all processes, procedures, hardware changes, configuration changes, checks, problems errors and so on, because SAP is so large and complex you cannot know everything or remember everything, documentation comes in handy when you are called in the middle of the night and are half asleep, it makes life so much easier just to pickup a documented process and follow that then to try and think on your feet.
