Hi,

if your work area and internal table structures are same then you can write,

APPEND 'workarea' to 'internal table'.

Hi this may be of some help to u:

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.

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.

Internal tables are used for storing records which are obtained as a result when we use select statement on database. internal tables are run time entities and doesn't occupy any memory. they are dynamic.

internal tables are of types.

1. internal tables with header line. [header and body]

2. internal tables with out header line. [only body]

Workarea is the concept which is mainly useful when working with internal tables with out header line.

at any point of time we can access only one record through header of a internal table. every thing should be done [inserting,modifying, reading ] through header only.

ex: data: itab like standard table of mara with header line.

for internal tables with out header line we will create a work area [explicit header] as type of table for storing data into internal table.

ex: data: itab like mara,

wa like mara.

Hema Sundara.

use append statement.

if work area is defined explictly,

append wa to itab.

clear wa.

if work area is along with itab,

append itab.
