How to validation for subscreen fields??

I am calling subcreen from my main screen, and in my subscreen I am having a select option and I want to do validation on select option if it is wrong then it should be enable.

I think so we can't use chain endchain for subscreens.

How to do this?

Thanks,

Sridhar,

do the validation in <b>at selection-screen on field</b> event as below.

At Selection-screen on field selfield1.

select <selfield1> from <dbtable> into table itab where field1 in <selfield1>.

if sy-subrc = 0.

do the process.

else.

exit.

endif.
