Hi ,

Both the validation and the selection must be done in the AT SELECTION SCREEN event .

First perform the validation , if an error occurs display the error mssage , if no error was there select the data and if required display the warning message.

Hi,

As you have declared your select-options under a block.

You can check the validation for the whole block fields under

Event-

AT SELECTION-SCREEN ON BLOCK B1.

In this case all fields under a block is input enabled and

outside block fields input diabled.

And if you want to check every single input field i.e. you can do

that under Event-

AT SELECTION-SCREEN ON <Fieldname>.

In this case only wrong input field is input enabled and other fields are input disabled.

If you use AT SELECTION-SCREEN.

Then all the fields in the selection screen are input enabled.

So use ablove Corresponding EVENT as according to your requirements.

Under each EVENT give 'E' Type Message , Program will not be processed further.for wrong input.

regards,

Sujit

in AT SELECTION-SCREEN event

[Former Member]

hi,

You can Validate ur material in

AT SELECTION-SCREEN ON <field> event.

U can check Validity and avalibility of material in this event block.

Rest if u want to validate each value seperately then use the above event otherwise put all fields under one block and validate them in

AT SELECTION-SCREEN ON BLOCK <block>

hope this will help.

reward if helpful

hi,

do all the validation in the AT SELECTION SCREEN events that are AT SELECTION SCREEN on field,

AT SELECTION SCREEN on block

or AT SELECTION SCREEN

whichever is applicable...

refer to the code below;

AT SELECTION-SCREEN on s_vbeln.

SELECT SINGLE vbeln " Sales document

FROM vbuk

INTO w_vbeln

WHERE vbeln IN s_vbeln.

IF sy-subrc <> 0.

MESSAGE e104(VF) WITH s_vbeln.

ENDIF. " IF SY-SUBRC <> 0

with luck,

pritam.
