Hi Experts,

Hi Poonam,

You can use SET CURSOR for this issue.

Check out this sample code.

DATA : it_vbak TYPE STANDARD TABLE OF vbak INITIAL SIZE 0 WITH HEADER LINE.

PARAMETERS : p_vbeln TYPE vbeln_va.

START-OF-SELECTION.

SELECT vbeln

erdat

erzet

FROM vbak

INTO CORRESPONDING FIELDS OF TABLE it_vbak

WHERE vbeln = p_vbeln.

IF sy-subrc NE 0.

SET CURSOR FIELD p_vbeln.

ELSE.

loop at it_vbak.

WRITE : / it_vbak-vbeln.

endloop.

ENDIF.

Cheers.

Hello Poonam,

Did you declare Message Class at the start of the report?

IF ITAB[] IS INITIAL.
MESSAGE I000 WITH TEXT-M1.
LEAVE LIST-PROCESSING.
ENDIF.

Hope this helps.
