[Former Member]

I am downloading data from my internal table to an excel file in a shared drive. But the problem is all the row are coming in one line instead of seperate lines. this is how i am calling

*download the data into the excel

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD

EXPORTING

FILENAME = '
srvsms\testfolderofsap\invoice1.xls'

FILETYPE = 'ASC'

APPEND = 'X'

WRITE_FIELD_SEPARATOR = 'X'

CHANGING

DATA_TAB = T_INVOICE[]

EXCEPTIONS

The next time when i upload a record , instead of appending to the new line in the excel it gets apended to the previous line.. this should not happen... wht shud i do.... thank u

Hi,

Try commenting the APPEND = 'X' statement.

This is required only if you want to append the data to existing file.

Hi,

In that Method there is One Parameter APPEND.

Pass APPEND = 'X'.

it will append the records insteed of Overwriting.

Check thi slink-

The problem is.. when the program is run in another system with office 2003,.. the lines are getting appended but in the same line.. but when doing in my system with office 2007,. the files are appended in seperate lines... what can be the issue

[Former Member]

The catual problem is,.. if the file is created for the first time by sap on a system with office 2003,. the isues occurs of appending in the same line.. but if the file is created with a system with office 2007 it works fine..

Hi,

just check this procedure it will give u write formatted output

Firstly export  the data to memory using the FM LIST_FROM_MEMORY. 

CALL FUNCTION 'LIST_FROM_MEMORY'
TABLES
listobject = t_listobject
EXCEPTIONS
not_found = 1
OTHERS = 2.
IF sy-subrc 0.
MESSAGE e000(su) WITH text-001.
ENDIF.

then i converted it into ASCII using LIST_TO_ASCI,

CALL FUNCTION 'LIST_TO_ASCI'
TABLES
listasci = t_xlstab
listobject = t_listobject
EXCEPTIONS
empty_list = 1
list_index_invalid = 2
OTHERS = 3.
IF sy-subrc NE 0.
MESSAGE e003(yuksdbfzs).
ENDIF.

This gives the data in ASCII format separated by '|' and the header has '-', dashes. If you use this internal table directly without any proccesing in SO_NEW_DOCUMENT_ATT_SEND_API1, then you will not get a good excel sheet attachment. To overcome this limitation, i used cl_abap_char_utilities=>newline and cl_abap_char_utilities=>horizontal_tab to add horizontal and vertical tabs to the internal table, replacing all occurences of '|' with 
cl_abap_char_utilities=>horizontal_tab.

Set the doc_type as 'XLS', create the body and header using the packing_list and pass the data to be downloaded to SO_NEW_DOCUMENT_ATT_SEND_API1 as contents_bin.
This will create an excel attachment.

Sample code for formatting the data for the attachment in excel format.
u2022	Format the data for excel file download 
LOOP AT t_xlstab INTO wa_xlstab .
DESCRIBE TABLE t_xlstab LINES lw_cnt.
CLEAR lw_sytabix.
lw_sytabix = sy-tabix.
u2022	If not new line then replace '|' by tabs 
IF NOT wa_xlstab EQ cl_abap_char_utilities=>newline.
REPLACE ALL OCCURRENCES OF '|' IN wa_xlstab
WITH cl_abap_char_utilities=>horizontal_tab.
MODIFY t_xlstab FROM wa_xlstab .
CLEAR wa_xlstab.
wa_xlstab = cl_abap_char_utilities=>newline.
IF lw_cnt NE 0 .
lw_sytabix = lw_sytabix + 1.
u2022	Insert new line for the excel data 
INSERT wa_xlstab INTO t_xlstab INDEX lw_sytabix.
lw_cnt = lw_cnt - 1.
ENDIF.
CLEAR wa_xlstab.
ENDIF.
ENDLOOP.
Sample code for creating attachment and sending mail:

FORM send_mail .
u2022	Define the attachment format 
lw_doc_type = 'XLS'.
u2022	Create the document which is to be sent 
lwa_doc_chng-obj_name = 'List'.
lwa_doc_chng-obj_descr = w_subject. "Subject
lwa_doc_chng-obj_langu = sy-langu.
u2022	Fill the document data and get size of message 
LOOP AT t_message.
lt_objtxt = t_message-line.
APPEND lt_objtxt.
ENDLOOP.

DESCRIBE TABLE lt_objtxt LINES lw_tab_lines.
IF lw_tab_lines GT 0.
READ TABLE lt_objtxt INDEX lw_tab_lines.
lwa_doc_chng-doc_size = ( lw_tab_lines - 1 ) * 255 + STRLEN( lt_objtxt ).
lwa_doc_chng-obj_langu = sy-langu.
lwa_doc_chng-sensitivty = 'F'.
ELSE.
lwa_doc_chng-doc_size = 0.
ENDIF.
u2022	Fill Packing List For the body of e-mail 
lt_packing_list-head_start = 1.
lt_packing_list-head_num = 0.
lt_packing_list-body_start = 1.
lt_packing_list-body_num = lw_tab_lines.
lt_packing_list-doc_type = 'RAW'.
APPEND lt_packing_list.
u2022	Create the attachment (the list itself) 
DESCRIBE TABLE t_xlstab LINES lw_tab_lines.
u2022	Fill the fields of the packing_list for creating the attachment: 
lt_packing_list-transf_bin = 'X'.
lt_packing_list-head_start = 1.
lt_packing_list-head_num = 0.
lt_packing_list-body_start = 1.
lt_packing_list-body_num = lw_tab_lines.
lt_packing_list-doc_type = lw_doc_type.
lt_packing_list-obj_name = 'Attach'.
lt_packing_list-obj_descr = w_docdesc.
lt_packing_list-doc_size = lw_tab_lines * 255.
APPEND lt_packing_list.
u2022	Fill the mail recipient list 
lt_reclist-rec_type = 'U'.
LOOP AT t_recipient_list.
lt_reclist-receiver = t_recipient_list-address.
APPEND lt_reclist.
ENDLOOP.
u2022	Finally send E-Mail 
CALL FUNCTION 'SO_NEW_DOCUMENT_ATT_SEND_API1'
EXPORTING
document_data = lwa_doc_chng
put_in_outbox = 'X'

IMPORTING
sent_to_all = lw_sent_to_all

packing_list = lt_packing_list
object_header = lt_objhead
contents_bin = t_xlstab

Hope it will help you
