lets say for example your lookup table is your target table. So when you create the Lookup selecting the dynamic cache what It does is it will lookup values and if there is no match it will insert the row in both the target and the lookup cache (hence the word dynamic cache it builds up as you go along), or if there is a match it will update the row in the target. On the other hand Static caches dont get updated when you do a lookup.
