'Erfassen' (to record/grasp) is an inseparable verb. It consists of the prefix 'er-' and the verb 'fassen' (to grasp/take hold of). The prefix 'er-' often suggests successful completion — so you successfully 'grasp' data, an idea, or a person.

'treffen' and 'erfassen' can both have to do with understanding something correctly. 'treffen' is used in phrases like 'den Kern treffen' (to get to the heart of the matter) or 'das Richtige treffen' (to hit on the right thing). Then it means: someone says or finds exactly what is essential. 'erfassen' means more that you understand something as a whole, for example a problem or an idea. So 'treffen' emphasizes the accuracy of a point, while 'erfassen' emphasizes understanding the whole context.
