selection screen validation

[Former Member]

Hello All,

Instead of doing a validation at selection screen. If I do the validation in start-of-selection and still want to make the message display at selection screen what should i do?

Thanks in advance

u have to do like this

start-of -selection

select kunnr name1 from kna1

into corresponding fields of table i_kna1

where kunnr in s_kunnr.

if sy-subrc ne 0.

message ' no customer found for this selection'

endif.

regards

suppose your selection screen parameter is s_matnr, u simply validate it like

if s_matnr ne 'the validatiopn value'.

message 'i001'.

there is no necessity of using the events .

Hi,

1. U are right, we can do so.

2. But we have to take care like this.

3.

START-OF-SELECTION.

IF WRONG CONDITION.

MESSAGE 'WRONG INPUT' TYPE 'I'.

LEAVE LIST-PROCESSING.

ENDIF.

WRITE 😕 'DATA'

4. Important point is

a)use message type I and not E

b) use leave list-processing.
