  IF sy-subrc = 0.

Assumed your table is itab and the tables workarea is ls_wa

ls_wa = 'xyz'.

modify itab from ls_wa index 4.

That's it.

basically the fool proof way is to read the table using the READ statement based on some KEY field, then move the new value to the field, and MODIFY it using the WA and specifing the INDEX.


read table itab into wa with key admino = '12345'.
if sy-subrc  = 0.
   itab-name = 'Peter'.
   modify itab from wa index sy-tabix.
endif.

WA would be typed like a line of your internal table. So say that you internal table, ITAB is typed like so..


data: itab type table of t001.

The WA would be typed like line of ITAB


data: wa like line of itab.

*Add some value to the itab

itab-firstname = 'pete'.

itab-lastname = 'zhang'.

append itab.

read table itab into wa with key firstname = 'pete'.

if sy-subrc = 0.

itab-lastname = 'lin'.

modify itab from wa index sy-tabix.

endif.

*check the itab for lastname change
