Hi rajesh,
Header is a workarea of the table which acts as an interface for the table. Header can have only one record at a time.
WORKAREA is a structure that can hold only one record at a time. It is a collection of fields. We use workarea as we cannot directly read from a table. In order to interact with a table we need workarea. When a Select Statement is executed on a table then the first record is read and put into the header of the table and from there put into the header or the workarea(of the same structure as that of the table)of the internal table and then transferred top the body of the internal table or directly displayed from the workarea.
Each row in a table is a record and each column is a field.
example,
internal table.
data: begin of itab occurs 0,
matnr like mara-matnr,
maktx like makt-maktx,
end of itab.
workarea.
data: begin of itab,
matnr like mara-matnr,
maktx like makt-maktx,
end of itab.
also,
workarea:
types: begin of type_mat,
matnr like mara-matnr,
maktx like makt-maktx,
end of type_mat.
internal table
data: t_mat type standard table of type_mat.
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.
