Hi,

I have made some changes on your code ,.

Now it is working fine.

Please check the following --

DATA:BEGIN OF ITAB OCCURS 0,
MATL_TYPE(4) TYPE C,
MATL_GROUP(9) TYPE C,
MATL_DESC(40) TYPE C,
CHAR_PROF(18) TYPE C,
END OF ITAB.

DATA:WA LIKE ITAB.
*DATA file TYPE string VALUE `/sap/inbound/bdc.txt`. " Commented

DATA FILE TYPE STRING VALUE 'BDC'. " Added

OPEN DATASET FILE FOR INPUT IN  BINARY MODE. " Not output, specify INPUT
IF SY-SUBRC EQ 0. " Added

  WRITE:'ok'.

  FIELD-SYMBOLS <HEX_CONTAINER> TYPE X.

  ASSIGN WA TO <HEX_CONTAINER> CASTING.

  DO.
    READ DATASET FILE INTO <HEX_CONTAINER>.
    IF SY-SUBRC = 0.
      WRITE: / WA-MATL_TYPE,
      WA-MATL_GROUP,
      WA-MATL_DESC,
      WA-CHAR_PROF.
    ELSE.
      EXIT.
    ENDIF.
  ENDDO.
ENDIF. " Added
CLOSE DATASET FILE.

Hi,

You should open in input mode for reading.

• Local variable Declaration

DATA l_msg(60) TYPE c.

• Opening the file for output in text mode

OPEN DATASET ....

MESSAGE l_msg.

In debugging mode, you can get the message in l_msg.

Hi Vipin,

Actullly Your OPEN DATASET .... statement was unsuccessful to open the

file `/sap/inbound/bdc.txt`.

And without checking SY-SUBRC the code was trying to read data from a file

which is not opened at all.That was causing the runtime error.

So after your OPEN DATASET ... statement you need to cheeck SY-SUBRC and

if it success then only you need to proceed.

Another thing is that if you want to read from a file to your report in that case

you need to open the file FOR INPUT .

Specify the file value properly.
