Mapping issue

I have a scenario...IDOC to File

i have got a segment in IDOC...which is at fourth level.I mean

IDOC

segment1

-

segment2

-

segment3

-

Segment4

i have a receiver field where i need try map this segment 4 to segment 4 at receiver.

Head

segment1

segment2

segment3

segment4

my question is

If we have segment 4 coming in from IDOC then only create segment 4 in destination file.

i tried

Segment4 ->exists -->Segemnt4

Segment4 ->remove context >exists---->Segemnt4

but not working

any ideas
