uplaod documents mayu be of .doc,.xls or .txt according to the ease we can select the FM's

FM for excel as it will have rows and columns

PARAMETER p_infile like rlgrap-filename.

call function u2018ALSM_EXCEL_TO_INTERNAL_TABLEu2019
exporting
filename                = p_infile
i_begin_col             = u20181u2032

Hi,

use function module GUI_UPLOAD to get data from any source file while the source file is in presentation server.

read the data using this function module into a table type of string. then split the string accordingly by the given separator and display them in any way you want.

but if the source file is in application server then use the following approach to read data in string format:

open dataset.

read dataset.

close dataset.

regards,

Prinan

Hi Hitesh Nangrani,

You can use the following function module to read a file and upload it to some internal table, inorder to use the data further.

I'll give you an example wherein theres a selection screen to select any file (word or excel) from ur PC and then upload it to an internal table.

Example :

Define a variable of type string to hold ur file name

Data : lv_file_name type string.

SELECTION SCREEN ***

Selection Screen to take the file, where p_f_name is the parameter of type rlgrap-filename and it is made mandatory & text-100 is a text field where u can give any description like "please input file path"

selection-screen begin of block b1 with frame title text-100.

parameters : p_f_name like rlgrap-filename obligatory.

selection-screen end of block b1.

AT SELECTION-SCREEN ***

at selection-screen on value-request for p_f_name.

Function Module To Open The Input File Containing The Input Values ***

following function module will open the file, in IMPORTING give the parameter p_f_name, which has the file path, it will open the file at that path i.e. the file u want

call function 'WS_FILENAME_GET'

EXPORTING

def_filename = 'C:\test.xls'

def_path = 'C:\'

mask = ',.,..'

mode = 'O' "O --> Open S --> Save

title = 'OPEN'

IMPORTING

filename = p_f_name

EXCEPTIONS

inv_winsys = 1

no_batch = 2

selection_cancel = 3

selection_error = 4

others = 5.

Assign the file path to the variable u had declared to hold the file name

START-OF-SELECTION ***

start-of-selection.

lv_file_name = p_f_name.

Function Module To Upload Input File To The Internal Table ***

following function module will read the file and transfer it data to the internal table

In FILENAME assign the filename variabe and in TABLES assign the internal table name in which u want the file data to come

call function 'GUI_UPLOAD'

EXPORTING

filename = lv_file_name

filetype = 'ASC'

has_field_separator = 'X'

TABLES

data_tab = lt_material_details.

NOTE : See to it that ur internal table has all the fields that are there in ur excel sheet / word, so that the contents of file properly go into respective fields of internal table. otherwise there would be mis-matching of fields and data.

Hope this reply would help you...do let me knw if it worked...All The Best

Regards,

Radhika
