radio button and selection screen

Former Member — Wed, 06 Jun 2007 01:49:31 GMT

my requirement is that if the user enters some particular combination of value in the select options and clicks a particular radio button there should be an error message displayed.

1) I am getting the error message in the form a dialog box , but it has only option of exit , and the user is thrown of the screen. my requirement is that after the error message the user must still be at the same screen so that he can enter new values.

2) the code that i have written also has one more anamoly that the displaying of error depends upon the sequence of actions .

if i enter the value in the select option first and then click the radio button then the error message is displayed which is correct.

but it doesnt work i click the radio button first and then enter the value, the program is executed and NO ERROR message is flashed.

here is what i have written

**********************************************************************************************

SELECTION-SCREEN BEGIN OF BLOCK blk WITH FRAME.

SELECTION-SCREEN BEGIN OF BLOCK blk1 WITH FRAME TITLE text-001.

SELECT-OPTIONS: p_year for s021-spmon obligatory ,

if nrw = 'X' and p_augru-low EQ 'MWD'.

Hi,

Instead of doing the validation the AT SELECTION-SCREEN OUTPUT..do it at AT SELECTION..event..

Also remove the LOOP AT SCREEN..

Modified code.

at selection-screen. " Commented OUTPUT

if nrw = 'X' and p_augru-low EQ 'MWD'. " Removed LOOP AT SCREEN.

MESSAGE e000(oo) WITH '<Please Enter the correct Order Reason>'.

endif.

Thanks,

Naren

Change this piece of code

at selection-screen output.

loop at screen.

if nrw = 'X' and p_augru-low EQ 'MWD'.

MESSAGE e000(oo) WITH '<Please Enter the correct Order Reason>'.

endif.

endloop.

<b>at selection-screen.

if nrw = 'X' and p_augru-low EQ 'MWD'.

MESSAGE e000(oo) WITH '<Please Enter the correct Order Reason>'.

endif.</b>

Reward points if useful.

Write all the validations in the event AT-SELECTION SCREEN

This will display the error message and still keep you on the same screen.
