1. WOrk area is a structure which holds the latest(last record)data. It is compulsory used with internal tables

with out header line because internal table concept is desgned like that either work area should be there or internal table should be with header line.

2. In call transaction method, while updating data itself, check sy-subrc, if sy-subrc <> 0 add the rcord to another internal table. In this way we can collect errorneous records into another internal table. once u know the records, we can easily delete using delete statement.

3. CURR->CUKY QUAN->UNIT

Hi,

1.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.

Hi,

1) workarea :- is a structure . whenever u declare internal table with header line . a workarea is attach to the internal table . u use internal_tablename-fieldname to acess the value .when read or loop is done with table name result is stored in the haeder.

when without headerline internal table is declared u have to use stucture( workarea ) store the value when u perform loop or read.

syntax:

read table intab into <structure>.

4) at top of the report.

along with report <reportname>. statement.

write statement like this

report <reportname> line-size 100.

report <reportname>........by default available.
