Answer / vaibhav budhkar

actually header line is old way manipulating data in the
internal table.
header line is same as that of workarea.
but the difference is that workarea needs to declared
explicitly, and header line gets created automatically when
we use OCCURS statement or WITH HEARDER LINE.

Answer / sunny

header line is consist in itab. When we create any itab
then header line is automatically created if we use occurs
0 and with header line. we use the header line to insert
the data into our itab. first the data will come into our
header line then it will insert into body of internal
table. We can insert only one line into the header line.

Work area can be our string or we can declare work area
anywhere in our programme. Through that work area we can
insert the data into our itab.

Answer / soham

With header line is old way to define work area as internal
table but that is not used better to use 'type standard
table of' for internal table and 'type' for work area.
that error occurs when we fetch more columns than in type
so avoid to use header line.
