DATA: l_index type sy-tabix.

loop at itab.

l_index = sy-tabix.

itab-field1 = 53. "changing the value.

modify itab index l_tabix.

endloop.

Note: sy-tabix value will be changed if any Loop statement or READ TABLE statement is given.

So, its good practise to either use field-symbols or store index value in some variable.

Check the new code using field-symbols.

FIELD-SYMOLS: <itab> type itab.

loop at itab assigning <itab>.

<itab>-field1 = 53.

endloop.

"No modify statement is required. Hence more optimized solution.

Hi Gowri ,

Use the modify command , since what i understand is you are using a internal table with header line so the modify statement will do.

i dont know by which way you are accessing the table.

if it is in loop at and endloop..

loop at itab.

itab-f1 = 'ABC'.

modify itab.

endloop.

here index sy-tabix is not necessary....

if you are accessing by read table statement...

read table itab with key f1 = 'ABC'.

if sy-subrc = 0.

itab-f1 = 'DEF'.

modify itab index sy-tabix.

endif.

here sy-tabix is necessary...
