Hi Ravi,

You can do validation on selection screen fields using AT SELECTION-SCREEN ON <SELCECTION-SCREEN FIELD>

after entering the values in the fields.

Just use E

Like this.

select-options: c_pernr type pernr-pernr.

at selection-screen .

Select single * from pa0002 where pernr = c_pernr.

if sy-subrc ne 0 .

message ' no data found' TYPE 'E'.

endif.

Ps: this is a basic thing in abap ravi...Doing a little bit r & d will solve u r problem..From next do little bit searching before posting.All the best

Hi,

Try this code

DATA WA_CARRID TYPE SCARR-CARRID.

PARAMETERS CARRID TYPE SCARR-CARRID.

AT SELECTION-SCREEN ON CARRID.

  SELECT SINGLE CARRID
  FROM SCARR INTO WA_CARRID
  WHERE CARRID = CARRID.

  IF SY-SUBRC IS NOT INITIAL.

    MESSAGE 'Carrier not present' TYPE 'E'.

  ENDIF.

START-OF-SELECTION.

WRITE  CARRID .
