Hi Nidhi,
I think, right now you are using Message(Information). If you want to display both ALV and message at a time, Use Message(Sucess) instead of Information.
"Data Declaration
DATA: L_MSG TYPE STRING.
"Success Record
CONCATENATE 'Success Record :' l_success into L_MSG SEPERATED BY SPACE.
"Fail Record
CONCATENATE L_MSG 'Fail Record :' l_fail into L_MSG SEPERATED BY SPACE.
"Show Message before ALV
MESSAGE L_MSG TYPE 'S'.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'.
