Validate parameter.

[Former Member]

Hi,

I want to validate a parameter:

PARAMETERS: quincena TYPE d.

I'm trying to use:

AT SELECTION-SCREEN ON quincena.

IF quincena EQ ''.

MESSAGE e000 WITH 'You must select one'.

ENDIF.

But it doesn't work, the program continues anyway.

Hi,

try this

IF quincena EQ '00000000'.

instead of this..

IF quincena EQ ''.

because the intial value for type d is '00000000'.

AT SELECTION-SCREEN ON quincena.

IF quincena EQ <b>'00000000'</b>.

MESSAGE e000 WITH 'You must select one'.

ENDIF.

Why don't you make this as mandatory?
