I can suggest 2 ways of obtaining the results:
1. Through source qualifier, filter and sequence generator:
From source qualifier get the total records count in one
port, say record_count and from sequence generator add an
input port, say record_number.
In the filter add the condition:
(record_number > 3) AND (record_number < (record_count - 2))
2. Using the following sql query: (not sure about the
results. Please confirm the same and suggest any updates if
required):
select key_field, DESCRIPTION from temp_table
where
ROWID NOT IN (SELECT ROWID FROM TEMP_TABLE WHERE ROWNUM <=
3)
AND ROWID IN (SELECT ROWID FROM TEMP_TABLE WHERE ROWNUM <=
(SELECT COUNT(*) FROM TEMP_TABLE) - 3)
In the above query temp_table is the table name, key_field
and Description are column names.

To skip first n of lines,
If source is DB, then use
