you can do the checking in at selection-screen output

at selection-screen output.

if not <field1 is initial.

*Do your validation here

if sy-subrc ne 0.

*throw error message

endif.

endif.

Hi,

E.g. if your field is say pa_vbeln & if it is initial you have to display error, then code as follows,

AT SELECTION-SCREEN ON pa_vbeln.

IF pa_vbeln IS INITIAL.

MESSAGE E000.

ENDIF.

similarly for the remaining fields .
