Answer / bsgsr

i believe this should work.

1) use the first and last functions of aggregate t/tion.
2) use the top option and 1 rank using rank t/tion
similarly last option and 1 rank to get only the first
and lst records.
3) else connect the flat file to filter t/tion. create new
port in filter name it s_no and connect the nextval port of
s.gen and write the contion (assume the file contains 100
records) like s_no=1 or s_no=100
