Hi Booby,

I am ot sure if I understood your question...Well here are the FM for uploading files:

1.'F4_FILENAME'

2. 'GUI_UPLOAD'

EXAMPLE

REPORT ZEX_READFILE_FROMDIR .

Data: d_filename like IBIPPARMS-PATH,

d_file type string.

data : begin of itab occurs 0,

values(1000) type c,

end of itab.

The following function module calls the File/Path Selector Dialog Box

CALL FUNCTION 'F4_FILENAME'

EXPORTING

PROGRAM_NAME = SYST-CPROG

DYNPRO_NUMBER = SYST-DYNNR

FIELD_NAME = ' '

IMPORTING

FILE_NAME = d_filename.

d_file = d_filename.

The following function module uploads the file into the internal table

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

FILENAME = d_file

FILETYPE = 'ASC'

HAS_FIELD_SEPARATOR = ' '

HEADER_LENGTH = 0

READ_BY_LINE = 'X'

DAT_MODE = ' '

TABLES

DATA_TAB = itab

EXCEPTIONS

FILE_OPEN_ERROR = 1

FILE_READ_ERROR = 2

NO_BATCH = 3

GUI_REFUSE_FILETRANSFER = 4

INVALID_TYPE = 5

NO_AUTHORITY = 6

UNKNOWN_ERROR = 7

BAD_DATA_FORMAT = 8

HEADER_NOT_ALLOWED = 9

SEPARATOR_NOT_ALLOWED = 10

HEADER_TOO_LONG = 11

UNKNOWN_DP_ERROR = 12

ACCESS_DENIED = 13

DP_OUT_OF_MEMORY = 14

DISK_FULL = 15

DP_TIMEOUT = 16

OTHERS = 17.

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

Output the internal Table

loop at itab.

Write:/ ITAB.

endloop.

Hi Bobby,

If you need to call a method in a class, what you need to do is :

Create an object of that class. And using that object, call its methods.

Check the perform call_alv_grid from below link:

http://wiki.sdn.sap.com/wiki/display/HOME/objectorientedProgramminginALV

It is calling method "set_table_for_first_display" of class "cl_gui_alv_grid".

If your question is still unanswered, please explain your requirement little more clearly....

Regards,

Nisha Vengal.
