1. If you know the signature of header and tailer record
then use filerby expression component to filter the header
and tailer records
2. Use one reformate component and then inside the
transformation use next_in_sequence() function to assign
unique numbers to each record,and then use filter by
expression component to filter the records based on
sequence numbers.
3.Follow the step 2 and use instead of filter by expression
component use leading records component to filter the
header and tailer records.

Generally there is a indicator for record type.
For ex If it is Header, the first byte would have H
Trailer,the first byte would have H
Define record types for each using conditional dml and
validate/remove junk data.

It is very common is DW environments to get source files
with header a trailers. Headers are commonly used to get
the Date of the file and trailers as control with the
number of detail records. Normally you have to make sure
you got the trailer to make sure you haven't received
source files partially
