Hi Phani,

Variables declared in the internal table are the fields.

Thanks,

If you are defining and internal table with header line the statement begins with stmt like

data:begin of itab occurs 0,

f1(2),

f2(5),

end of itab..

Here f1 and f2 are fields of itab. I general what are the things you are defining in between 'begin' and 'end' are internal table fields..

Hi sdn,

Is there any system fields, are used on internal table only?

Hi,

SY-TABIX

Current line of an internal table. It is set only for index tables. The field is either not set or is set to 0 for hashed tables. It iset by ABAP commands APPEND,COLLECT,LOOP AT,READ TABLE,SAERCH itab FOR .

SY-TFILL

After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TFILL contains the number of lines in the relevant internal table.

Database Access

SY-DBCNT

It contains the number of table entries processed. In an loop it is not set until after the ENDSELECT or ENDEXEC statement. It is set by ABAP

Hi,

variables defined within the 'begin of' and 'end of' statements are the fields of an internal table. In technical terms Internal table is a dynamic sequential dataset in which all records have the same data structure and a key.

In my opinion the asked question was wrong.
