using open dataset get the file into the internal table modify it and re write to the same path.

to read the file into internal table.

OPEN DATASET p_ufile FOR INPUT IN TEXT MODE.
IF sy-subrc <> 0.
EXIT.
ENDIF.

DO.
READ DATASET p_ufile INTO wa_file.
IF sy-subrc <> 0.
EXIT.
ENDIF.
ASSIGN wa_file TO <wa_table>.
APPEND <wa_table> TO p_table.
CLEAR wa_file.
ENDDO.

CLOSE DATASET p_ufile.
ENDIF.

modify ur p_table as per ur requirement..

to re-write file back to the same path.


OPEN DATASET p_ufile FOR OUTPUT IN TEXT MODE.
IF sy-subrc <> 0.
EXIT.
ENDIF.
LOOP AT p_output INTO wa_file.
TRANSFER wa_file TO p_ufile.
CLEAR wa_file.
ENDLOOP.
CLOSE DATASET p_ufile.
