Answer Posted / mahendra patnaik
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.
