Using FM SO_OBJECT_DOWNLOAD

Hi all,

I am having problem in using this FM. I want to download any file to my local desktop from the file attachment list of an employee in PA20/PA30. I kept on getting Access via 'NULL' object reference not possible error message.

This is how I use it. The filename is obtained through the a pop up box asking user to input a file name with a file path.

CALL FUNCTION 'SO_OBJECT_DOWNLOAD'

EXPORTING

• BIN_FILESIZE = 0

• DEFAULT_FILENAME = ' '

filetype = 'BIN'

path_and_file = lo_stru_output_param-file_name "C:\Users\sc\Desktop\xyz.pdf

• EXTCT = ' '

no_dialog = ' '

• CODEPAGE =

• IMPORTING

• FILELENGTH =

• F_CANCELLED =

• ACT_FILETYPE =

• ACT_FILENAME =

TABLES

objcont = lt_object_cont

EXCEPTIONS

file_write_error = 1

invalid_type = 2

x_error = 3

kpro_error = 4

OTHERS = 5

.

IF sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.
