hi manikantha,

the term validation means whenever u want a valid data for a valid input then u should go for validation...

this is generally written in following events,

AT SELECTION-SCREEN OUTPUT

AT SELECTION-SCREEN

for example if u want to check whether the input field is blank ...then u should use the following code

AT SELECTION-SCREEN.

if field is initial.

message 'please enter value' type 'E'.

endif.

hope this may help u out....

please reward incase usefull...

regards,

Under this event

AT SELECTION-SCREEN " do all your validations of selection screen

AT SELECTION-SCREEN ON <FIELD> " do validation for particular field.

Reward points if useful.
