  IF p_matnr IS NOT INITIAL.
    SELECT SINGLE matnr
      INTO w_matnr
      FROM mara
    WHERE matnr EQ p_matnr.

    CHECK sy-subrc NE 0.
    SET CURSOR FIELD 'P_MATNR'.

Hi,

you can validate single field validaions by using this syntax.

at selection-screen on <fieldname parameter/select-option>.

select single * from <dbtable> where condition.

if sy-dubrc ne 0.

error message.

endif.

hi,

For your requirement you can use the selection-screen event at selection-screen on field.

AT SELECTION-SCREEN ON <field>

is triggered when the contents of each individual input field are passed from the selection screen to the ABAP program. The input field <field> can be checked in the corresponding event block. If an error message occurs within this event block, the corresponding field is made ready for input again on the selection screen.

Hiii!

Do the validation of that particular field in the event

AT SELECTION-SCREEN ON <field>.

By this event, only this field will be active, in case you put wrong value in it

Hi,

If you want to validate particular single field the validate in

AT SELECTION-SCREEN ON FIELD <field-name>.

AT SELECTION-SCREEN ON FIELD p_matnr.

if p_matnr is initial.

message e012<message-class-name> .

endif.

So, when you execute this event is triggered and checks the condition . if the P_MATNR fields is empty then it show ERROR message and cursor will be shown in that field. Until you correct that error it will not allow you to go further.

Regards,

Rajitha.

Hello,

To validate a particular screen-field,use the event .

AT SELECTION-SCREEN ON FIELD <field-name>.

Example:-

AT SELECTION-SCREEN ON FIELD p_flight.
if p_flight is initial.
message  'field is empty ' type 'I'.
endif

IF you execute your program, it checks field p_flight . If p_flight field is empty then gives the message and cursor is placed on p_flight .
