Selection screen processing

[Former Member]

Dear all,

I've got a selection screen with two select-options fields for which I would like to make a check:

If field 1 and field 2 are empty then triggering an Error message.

For this I thought to use the "at selection-screen block" combined with

if field 1 and field 2 is initial.

message...

endif.

But in that case, I can not use any more the multiple selection button (at the right of the field) becase I have my event "at selection-screen block" triggered with the error message.

I tried to declare my message after the start of selection but then I have a new empty screen with my error message on the bottom of it.

How to deal with that?

Regards.

perform ur validation in <b>AT SELECTION-SCREEN</b> event instead of <b>AT SELECTION-SCREEN block</b>

I've tried that but it is the same:

Error message triggered when I try to use the multiple selection.

Hi,

Yes of course.

But the thing is that there is some condition for the OBLIGATORY:

If field 1 empty then only field 2 obligatory and if field 2 empty then only field 1 obligatory.

at selection-screen.

if field1 is initial and field2 is initial.

message e000 with 'Please enter either of the values'.

endif.

[Former Member]

Thanks but then I can not use any more the multiple selection function.

hi,

instead of showing ur message as an ERROR MSG (TYPE E)

show it as information msg (type i) or sucess msg (type S)

and use STOP command immediately after it so that it remains on the selection screen only

[varma_narayana]

Hi

this Validation and Error Message must be done in the Event AT SELECTION-SCREEN.

Then it solves ur problem.

REWARD IF HELPFUL.

Hi

AT SELECTION-SCREEN.

if sy-ucomm = 'ONLI'. "Only when you execute the program

if field1 is initial....Your condition for giving error.

endif.
