Hi Subhasis,

Selection Screen is validated at the event

AT SELECTION SCREEN.

In this event you check the input parameters with the values in DB and if they are not matching you can give an error message to the error of the same.

Reward points if useful.

Hi,

Based on the input parameter validations can be takes place. Let us take some example u take company code on ur selection screen, then user should enter that company code then instead of using obligatory u can do some validataion like

IF P_BUKRS IS INITIAL.

MESSAGE E001(ZFE) WITH 'PLEASE ENTER COMPANY CODE'.

LEAVE TO SCREEN 1000.

ENDIF.

this is the validation.

Hope this helps you. Reply for queries, shall post the updates.

there are diffrent validation,

if you want to get f4 value

then you need to write :

at selection-screen on value-request for p_file.

if you want to validate selection-screen values..

at selection-screen on p_matnr.

if you want to get dynamic validation like set up password,invisible,disable..

use at selection-screen output.

loop at screen.

endloop.

hi,

If you need to validata a material number s_matnr.. which is your sel;ect option in selection screen,,

then

<b>At selection-screen on s_matnr.</b>

data lv_matnr type matnr.

select single matnr from mara

into lv_matnr

where matnr in s_matnr.

• since matnr is the only primary key in mara we are using select single..

*if for some other field which is a part of primary key in that table then use select upto 1 rows..

is sy-subrc <> 0.

Message i001."enter valid material number..

endif.

<b>At selection-screen on s_matnr.</b> , if you use this and if error occured for invalid material number then all the other parametersa in selection screen will be disabled point to only s_matnr enable in your selection screen..

if you use just At selection-screen then the cursor will not point to matnr but only to the first parameter in the selection screen..

hope you understood

rewards if useful,

at selection-scren is basically used to check the input s in the selection screen via a logic, if the inputs are not according to that logic we will raise an error message through which the system will take back the user to the selection screen.

there are some more at selection-screen

like

At selection-screen on field - If ilogic is related to only a particular field

at selection-screen on value help - for writing F4 logic

at selection-screen on help - for writing F1

etc.,

go through the below underlined programs

Selection Screen Events - <u>demo_selection_screen_events</u>

PBO of selection Screen - <u>demo_at_selection_screen_pbo</u>

Hope this will solve ur problem..

hi,

selection-screen validation is nothing but getting the proper values as input at selction screen level.means checking the values which you are passing at selection screen values.

for this u can use AT SELECTION-SCREEN.

suppose u need u validate MATNR on u r selection screen.in this case we can validate the MATNR is there in the table MVKE or not.

u can write like

select-options: s_matnr for mvke-matnr.

at selection-screen.

data : v_matnr type mvke-matnr.

select single matnr

from mvke

into v_matnr

where matnr in s_matnr.

if sy-subrc ne 0.

message e001.

else.

clear v_matnr.

endif.

reward if it is useful.

Thanks,

Madhukar.
