Hi Pallavi 1.

Loop at itab.
move 'a' to itab-a.
move 'b' to itab-b.
endloop.

You are just moving two different values to two different field of work area of internal tabl itab.if u want to append those two field into body of the internal table use APPEND itab. or if u want to modify the record of itab use MODIFY itab index sy-tabix transporting a b. 2.Occurs 0 The initial memory requirement defined during the creation of the internal table. 3.Occurs 10 Making 10 time The initial memory requirement defined during the creation of the internal table.

Pallavi,

the piece of code

Loop at itab.

move 'a' to itab-a.

move 'b' to itab-b.

endloop.

Moves the values 'a' and 'b' to the header line itab of the internal table itab....

so after this ...the field a in the headerline will contain the value 'a' and the field b will contain the value 'b'

The occurs statement is for the initial memory requirement

Hi Pallavi,

Loop at itab.

move 'a' to itab-a.

move 'b' to itab-b.

endloop.

Ur internal table itab has fields a and b and is defined with header line(Since u r not using any wa). This loop will do nothing as functionalitywise. When u enter into first looppass

ur first record of the table will be moved to headerline itab. Now The MOVE statements will move the hard coded value a to field a and b to field b. Ur table content will not change since u r not using Modify statement. If u want to MODIFY the table content then do like below.

Loop at itab.

move 'a' to itab-a.

move 'b' to itab-b.

MODIFY itab.

endloop.

After this all records of ur internal table has value a in field a and b in field b.

Hope this clarified ur doubts.

Thanks,

Vinod.
