validate select option in webdynpro


Hello Gurus,

I have created a webdynpro application including a select option(matnr) and alv table.Now my problem is without entering any data into select option , if the user clicks on submit button whole data related to matnr is shown.

How could I validate it with message to enter matnr first.

I wrote the code in WDDOBEFOREACTION but its not working.

Thanks in advance
