How do you validate the selection criteria of a report?

And how do you display initial values in a selection screen?

Re: general

hii...

Use selection-screen events to validate selection-screen and use initialization to give initial values to a selection-screen.

screen-events

at selection-screen output.

at selection-screen on value request

at selection-screen on help request

at selection-screen on block

select-options : s_matnr for mara-matnr default '10000' [to '20000']. <for default value to is not mandatory>.

at selection-screen.

if s_matnr-low = '10005'.

message 'chose any other mat no' type 'E'.

endif.

start-of-selection.

Use "AT SELECTION SCREEN ON FIELD." Event for Validation.

IF NOT p_werks IS INITIAL.

SELECT SINGLE werks

FROM t001w

INTO t001w

WHERE werks EQ p_werks.

IF not success

IF sy-subrc NE 0.

MESSAGE e001 WITH text-028.

ENDIF.

Hi Pinky,

By using the events we can get the Intial vales on the selection screen.

We can validate the fields by using the events.

INITIALIZATION Events provide the values on the selection screen.

AT SELECTION-SCREEN OUTPUT OR ON FIELD:

by using this function module we can validate the field or if u want to disable the screen or enable the screen this event we have to use.

If u want i will send the program.

******Rewards some points.

Initial value is displayed by initilization event.

Ex:

Parameter p_locl  RADIOBUTTON GROUP g1.

initilization.

p_locl = 'X'.

Else you can also give in initial value while declaration like this:

PARAMETERS: p_locl RADIOBUTTON GROUP g1 " desktop file

DEFAULT 'X' USER-COMMAND fil.

Selection criteria will be validated in AT SELECTION-SCREEN.or AT SELECTION-SCREEN ON event.

Use AT-Selection screen event to validate screen fields.

for default values use VALUE addition in parameter.

Hi,

IN THE EVENT AT SELECTION-SCREEN we write the code

select-options: s_vkorg for tvko-vkorg ,

s_vtweg for tvtw-vtweg .

Validation of Sales Organization

clear tvko.

if not s_vkorg-low is initial.

select vkorg from tvko up to 1 rows

into tvko-vkorg

where vkorg in s_vkorg.

endselect.

if sy-subrc ne 0.

message e009. " Invalid Sales Organization

endif.

Validation of Distribution Channel

clear tvtw.

if not s_vtweg-low is initial.

select vtweg from tvtw up to 1 rows

into tvtw-vtweg

where vtweg in s_vtweg.

endselect.

if sy-subrc ne 0.

message e010. " Invalid Distribution Channel

endif.

In the INITIALIZATION event you can initilize the values

Initialization.

s_vkorg-low = '1000'.

s_vkorg-sign = 'I'.

s_vkorg-option = 'EQ'.

append s_vkorg.

s_vkorg-low = '1001'.

s_vkorg-sign = 'I'.

s_vkorg-option = 'EQ'.

append s_vkorg.

hi dinky,

u can validate the user input in the at selection-screen event.

To display display default values u can use this within a selection screen event.

select-options : mat for mara-matnr default mat-low = '100' and mat-high = '200'.

Arun.
