While adding or retrieving records to / from internal table we have to keep the record temporarily.

The area where this record is kept is called as work area for the internal table. The area must have the same structure as that of internal table. An internal table consists of a body and an optional header line.

Header line is a implicit work area for the internal table. It depends on how the internal table is declared that the itab will have the header line or not.

e.g.

data: begin of itab occurs 10,

ab type c,

cd type i,

end of itab. " this table will have the header line.

data: wa_itab like itab. " explicit work area for itab

data: itab1 like itab occurs 10. " table is without header line.

The header line is a field string with the same structure as a row of the body, but it can only hold a single row.

It is a buffer used to hold each record before it is added or each record as it is retrieved from the internal table. It is the default work area for the internal table

Header we use this word with respect to Internal Tables

For an internal table if you say Header means foirst when the record is fetched from DB table it will enter into the Work area of Header and then it is moved to Body line by line when we use APPEND statement

WORK area means the place to keep/Store a Single record .

When you declare a table using

TABLES: MARA

this will create a work area for MARA to hold/store a single record of mara
