Hi supriya,

To validate the field you can give F4 help to it and pass the internal table to it, which has valid entries. or

you can put a SELECT SINGLE <> to the entry from that table, if sy-subrc eq 0 then data is valid.

hope its helpfull.

Hi,

There is no function module available. You can validate in

AT SELECTION-SCREEN ON <field> event.

hiii

there is no such FM which can validate entered value..but yes you can enter some already validated values by using following FM

F4_FIELD_ON_VALUE_REQUEST

F4IF_FIELD_VALUE_REQUEST

F4IF_INT_TABLE_VALUE_REQUEST

F4IF_START_VALUE_REQUEST

and you can also validate entered value by using select query for that entered value like

CHECK s_matnr IS NOT INITIAL.

  SELECT matnr
    INTO w_matnr
    FROM mara
    UP TO 1 ROWS
    WHERE matnr IN s_matnr.
  ENDSELECT.

  CHECK sy-subrc NE 0.

  SET CURSOR FIELD 'S_MATNR'.
  MESSAGE e010(zmsg).                  " Invalid Material
