l_flag = 'X'.

Hello Neha,

if not ls_tab-f1 in S_f1 means S_F1 may be a range table.

So they are check is_itab-f1 value is not in that range table.

If useful reward.

Basically the above condition checks the data for field f1 in ls_tab in the select-option for s_f1. If the data is not found than the condition is true.

In short, if the data for field f1 is not in S_f1. the flag l_flag would be set to 'X'.

Hi Neha,

In a logical expression with language element IN, the conditions of a selection table are checked. Selection table is a global internal table with a header line, the columns SIGN, OPTION, LOW and HIGH and the name of a selection criterion. Information about these columns you can find in the description of the select-options statement.

So the statement

 if not ls_tab-f1 in S_f1

means that the code under it will be performed if the field f1 of structure ls_tab doesn't satisfy the conditions in the table s_f1.

P.S.I see you are novice at this forum. So I kindly ask you to mark all of your questions as answered and award points for helpful answers.

HI Neha,

Seems you are trying to check value from your SELECT-OPTION in the loop of internal table.

Refer sample code ...

tables:mara.

select-options: s_f1 for mara-MTART.

types: begin of ty_itab,

Document type char4,

type1 type char4,

end of ty_itab.

data: wa_itab type ty_itab,

wa_itab1 type ty_itab,

itab type standard table of ty_itab.

wa_itab-document = '1000'.

wa_itab-type1 = '1234'.

append wa_itab to itab.

clear wa_itab.

wa_itab-document = '1001'.

wa_itab-type1 = '12345'.

append wa_itab to itab.

clear wa_itab.

wa_itab-document = '1002'.

wa_itab-type1 = ''.

append wa_itab to itab.

clear wa_itab.

<b><b>data: wa_selopt type selopt.</b></b>

loop at itab into wa_itab.

if wa_itab-document in s_f1.

write:/ 'true'. " can check your flag l_flag = X

elseif.

Continue.

endif.

endloop.

Copy this code and execute. Enter 1000,1001 & 1002 in select-option and see in Debug mode. will understand better.

Reward pints if this helps.
