Hi,

Fieldd symbols are like the pointers, It will just point the particular record of the internal table.So if you make any changes in the field symbols inside the loop, it will affect the record in the internal table... So no need to use the MODIFY statement....

Sample code :

FIELD-SYMBOLS : <fs_report> like it_report.

LOOP AT it_report ASSIGNING <fs_report>.

PERFORM f_get_info_from_it_febko.

<fs_report>-hbkid = wa_febko-hbkid.
<fs_report>-hktid = wa_febko-hktid.
<fs_report>-bukrs = wa_febko-bukrs.


PERFORM f_get_txt20.
<fs_report>-txt20 = wa_t028e-txt20.

PERFORM f_get_vwezw.
<fs_report>-vwezw_txt = vwezw_txt.
ENDLOOP.

Hello,

I am using Senthil's example as reference, you have to change the field-symbol to LIKE LINE OF:

FIELD-SYMBOLS : <fs_report> LIKE LINE OF it_report.
