Hi,

I have one query regarding internal table.

gs_itab-name1 = ls_lfa1-name1.

append gs_itab to gt_itab.

now i did some calculation & calculated TAXBS.

gs_itab-taxbs = lv_taxbs.

*now my req is to populate the taxbs in my internal table gt_itab.

hi,

Append statement will add another record at the last. it will not modify any records so use modify statement.

Use append lines of instead of normal append statement.

Hi salil,

1. Instead of using append and then modify,

use append once only, at the last.

2. In this sequence.

gs_itab-land1 = ls_lfa1-land1.

gs_itab-name1 = ls_lfa1-name1

now i did some calculation & calculated TAXBS.

gs_itab-taxbs = lv_taxbs.

append gs_itab to gt_itab

if you are adding new record to anternal table use append only,

I think u r requirement is to modify one field of each record in an internal table.

to achive this use the Field-symbols. don't use modify, fielsd syibols are is better way.

FIELD-SYMBOLS: <FS_L_WA_itab> TYPE ty_itab.

loop at gs_itab assigning <fs_wa_itab>

<fs_wa_itab>-taxbs = lv_taxbs

endloop.

Hi Sahil ,

If this code which you have written is in a loop endloop. , then what i suggest is that you calculate all the values first and then append.

Hi ,

U can do it in two fashions

first : u can use append statement at the last...which will just insert the record to ur table at last

second : u can use modify statement...

modify internal table from work area transporting fields where condition..

Hi Salil Singh,

The following is best approach as if your using standrad table.

modify gt_itab from gs_itab transporting taxbs.

Hello Salil,

Case 1:

By assuming you are appending the rows in the internal table inside the loop I'm giving my answer,

Better do what ever calculation you want and then append the waork area to internal table.

gs_itab-land1 = ls_lfa1-land1.

gs_itab-name1 = ls_lfa1-name1.

now i did some calculation & calculated TAXBS.

gs_itab-taxbs = lv_taxbs.

Now append

append gs_itab to gt_itab.

Case 2:

By assuming that you already appended the entries in to internal table my answer here as follows provided the modification operation should be inside the loop,

loop at gt_itab into gs_itab.

now i did some calculation & calculated TAXBS.

gs_itab-taxbs = lv_taxbs.

modify gt_itab from gs_itab transporting taxbs.

endloop.

Note: The keyword "Transporting" is very important. Otherwise u cant see the changes made to this field "TAXBS".

Hope u understood.
