Error Message while executing
What happened?
    At the conversion of a text from codepage '4110' to codepage '4102':
    - a character was found that cannot be displayed in one of the two
    codepages;
    - or it was detected that this conversion is not supported
    The running ABAP program 'ZHDI_LOMM_VEHI_MAT_MASS_CREATE' had to be terminated
     as the conversion
    would have produced incorrect data.
    The number of characters that could not be displayed (and therefore not
    be converted), is 449. If this number is 0, the second error case, as
    mentioned above, has occurred.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_CONVERSION_CODEPAGE', was not
     caught in
    procedure "F_DATA_UPLOAD" "(FORM)", nor was it propagated by a RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    Characters are always displayed in only a certain codepage. Many
    codepages only define a limited set of characters. If a text from a
    codepage should be converted into another codepage, and if this text
    contains characters that are not defined in one of the two codepages, a
    conversion error occurs.
    Moreover, a conversion error can occur if one of the needed codepages
    '4110' or '4102' is not known to the system.
    If the conversion error occurred at read or write of screen, the file
    name was '/usr/sap/interfaces/conversion/pioneer/ddm/data/test_data1.xls'.
     (further information about the file: "X 549

Fetch excel file from app. server using open dataset...

Hello Experts,
Our functional consultant is asking me if it possible to get an excel file from the
application server file using OPEN dataset and in background mode? If yes, Please tell me on how to do this.
Thank you guys and take care!

Hi Viraylab,
to download this the procedure:
you can use the FM 'EXCEL_OLE_STANDARD_DAT ' for this purpose.
this FM 'EXCEL_OLE_STANDARD_DAT' can be used to start Excel with a new sheet and transfer data from an internal table to the sheet.
Here are some of the parameters:
file_name: Name and path of the Excel worksheet file e.g. ?C:TEMPZTEST?
data_tab: Name of the internal table that should be uploaded to Exvcel
fieldnames: Internal tabel with column headers
How to build the field names table:
data: begin of i_fieldnames occurs 20,
field(60), end of i_fieldnames.
i_fieldnames-field = ?This is column 1?. append i_fieldnames-field.
i_fieldnames-field = ?This is column 2?. append i_fieldnames-field.
to upload follow this:
OPEN DATASET dsn FOR INPUT IN BINARY MODE.
DO.
READ DATASET dsn INTO itab-field.
IF sy-subrc = 0.
APPEND itab.
ELSE.
EXIT.
ENDIF.
ENDDO.

Create Excel file in application server but the field value is incorrect

Hi Experts,
i am facing a problem when create excel file in application server using OPEN DATASET command.
the internal table have 4 field and one of those field contains 19 digit number --> ICCID.
the code running well, successfully create EXCELfile in application server but the problem is SAP only copy exactly first 15 digit numeric only and the rest became zero 0
Example :
the field value in internal table is 8962118800000447654 but when i opened in the excel file the value became 8962118800000440000.
and if i add alphabet like a8962118800000447654 then it is correct.
is there is anything wrong with my code?
here is my code
CONSTANTS: c_tab TYPE abap_char1 VALUE cl_abap_char_utilities=>horizontal_tab. "Tab Char
Data : begin of lt_zdsdmmdt00005 occurs 0,
         SERNR (18) type c,

         BOX1 (20) type c,
         ICCID(30) type c,
       end of lt_zdsdmmdt00005.
data : ld_temp(100) type c.
i_file = '/usr/sap/DM/test_excel.xls'.
open dataset i_file for output in legacy text mode.
loop at lt_zdsdmmdt00005.
    move lt_zdsdmmdt00005-ICCID to ld_iccid .
    concatenate lt_zdsdmmdt00005-sernr lt_zdsdmmdt00005-MSISDN lt_zdsdmmdt00005-BOX1 ld_iccid

Problem in creating a file on Application Server

Hi,
I am facing an issue while creating a file on the application server.
I am creating a file with sales data from SAP and saving it on the application server.
At the end of this operation, I am calling a Unix script to push this file from SAP to an external system.
The issue I am facing is - at every month end, when I run a job for creating the file (its a custom program which is scheduled to run periodically), I get a strange scenario where a BLANK FILE gets created on the application server even though the data tables are not blank.
Also the user id gets changed to UID = 1400 when I run this job for the first time when a BLANK FILE gets created.
When I delete this file and run the job again, though, the file gets created WITH DATA.
The user name remains DEVADM (Dev Admin), as it should be for the scheduled jobs.
What could be the possible reasons for this?
Please help me in this direction.
Thank you.
Regards,
Keerthi

Hi,
You are using OPEN DATASET ? And what is the sy-subrc ?

Creating a file on application server that exceeds 10 Million charecters

Hello All,
We have custom IDocs which carry Strings of 1062 characters in each of their segments.
Now the requirement is to create a single string file out of these idocs data.
It is expected that each of these IDocs can go up to having more than 70,000 segments.
So, now when this is concatenated into one single string it can go upto 7 Million charecters.
My questions are:
1. Can we create a text file with so many charecters in a single line or is there any limitation for this ?
2. I have found a datatype CHAR30000, using which i'm currently concatnating around 30 segment data and then writing onto the file. Now once I wrote a single line, how can I set the pointer to End of line ?
3. Is there any limitation in ABAP to create such a long string text file using method mentioned above ?
Thanks for responding back!!
-Sri

No, It should be something like below.. for writing the file onto application server , which aint working though...
*Writing output data into the file.
lw_endofline = 30000.
OPEN DATASET p_fileop FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
LOOP AT int_output INTO wa_output.
    TRANSFER wa_output-sdata TO p_fileop.
    "SET DATASET p_fileop POSITION lw_endofline.
    SET DATASET p_fileop POSITION lw_endofline.
    lw_endofline = lw_endofline + 30000.
ENDLOOP.
CLOSE DATASET p_fileop.

OPEN DATASET create .txt file in application server

Hi,
I'm trying to create a .txt into application server. Code as follows:-
OPEN DATASET gv_filestatus FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
IF sy-subrc <> 0.
    WRITE: 'File cannot be opened.'.
ENDIF.
LOOP AT gt_pdfstatus INTO gw_pdfstatus.
    TRANSFER gw_pdfstatus TO gv_filestatus.
ENDLOOP.
CLEAR gw_pdfstatus.
CLOSE DATASET gv_filestatus.
But I got the error "GW_PDFSTATUS" cannot be a table, a reference, a string, or contain any of these objects. GW_PDFSTATUS is a work area with 5 fields of different type. I know that I can transfer table type of TLINE but I'm not sure how to convert my internal table gt_pdfstatus as TLINE.
Please advise. Thanks.

When transfering data to a file, you should convert the data to type char and then transfer it to the file.
So, you would need to declare a structure with 5 fields of type c with the corresponding length of the original structure.
Then move the corresponding fields of work are gw_pdfstatus to the character type structure. And then transfer the new structure to the file (gv_filestatus in your case).
"for example if all the fields in the gw_pdfstatus are of lenght 10, then declare a structure as follows
data : begin of file_wa,
f1(10) type c,
f2(10) type c,
f3(10) type c,
f4(10) type c,
f5(10) type c,
end of file_wa.
OPEN DATASET gv_filestatus FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
IF sy-subrc 0.
    WRITE: 'File cannot be opened.'.
ENDIF.
LOOP AT gt_pdfstatus INTO gw_pdfstatus.
    move-corresponding gw_pdfstatus to file_wa. " Add this
    TRANSFER file_wa TO gv_filestatus.   " Change this line
ENDLOOP.
CLEAR gw_pdfstatus.
CLOSE DATASET gv_filestatus.
Hope this helps.

I dont know how to do this.
Kindly give me the code, please it wil be helpfull for you all.
I dont know how to use the auth object or function module, to do this.
Is the basis/security people need to do something.
Kindly revert me back ASAP.
KK

Or use AUTHORITY_CHECK_DATASET function module before the open data set
This function module allow you to check the user's authorization to access files (with the key words OPEN DATASET, READ DATASET, TRANSFER and DELETE DATASET). A check should be performed before opening a file.
The authorization check is performed uwing the authorization object S_DATASET.
Description of function parameters:
PROGRAM: Name of the ABAP/4 program that contains the file access. If no program name is specified, the system assumes the current program.
ACTIVITY: Access type. The possible values are:
READ: Read file
WRITE: Change file
READ_WITH_FILTER: Read file with filter function
WRITE_WITH_FILTER: Change file with filter function
DELETE: Delete file
FILENAME: Name of accessed file
Example
Notes
The values to be passed as the ACTIVITY are defined as constants in the TYPE-POOL SABC.

To access pdf files from application server using web.show_document

Hello!
If my pdf file is copied in Oracle_home/forms90/java directory.Then using web.show_document i can access the pdf file.But I can't copy all the pdf files in /forms90/java directory.We have lacs of pdf files which I want to keep in my own directory.But my requirement is if my pdf file is in /home2/docs directory in (Linux application server) ie in my own directory where I store all the pdf files.Then web.show_document does not open the pdf file.It says page cannot be displayed.For that I think we have to configure the directory /home2/docs directory as a webserver.From otn I got something like forms90.conf file in application server where we have to set virtual directory mapping etc.If the pdf is in local machine then in orion-web.xml file we have to mention real path and save the file and shutdown oc4j instance and restart it again.I tried it.But it is not working.Can u give me step by step instructions to solve this problem.I found a few links in discussion forum.But is doesn't work out.My pdf file is in /home2/docs directory in Linux application server.Please treat it as urgent.
Regards
Jayashree

Hi Sandeepmsandy,
There is no available code sample for this scenario. You may write your own.
Step 1: Get pdf URL from sqlite database. Please refer to the following MSDN blog and see a code sample.
http://blogs.msdn.com/b/robertgreen/archive/2012/11/13/using-sqlite-in-windows-store-apps.aspx. Note, you need to retarget the project to 8.1 and then get two sqlite packages from NuGet before building this sample.
Step 2: Use some special classes to get file from serer.
HttpWebRequest can help download small pdf files. For more information to see
https://social.msdn.microsoft.com/Forums/windowsapps/en-US/de96a61c-e089-4595-8349-612be5d23ee6/download-file-with-httpwebrequest?forum=winappswithcsharp. It’s easy for use, but if you want to download the larger or many files, it’s recommend to use
BackgroundTransfer namespace. The classes in this namespace provide a power way to transfer files in the background. See a code sample from MSND.

I would like to upload xml file from app. server but parser failed. If I upload this xml file from workstation (using ws_upload) it is correct. For uploading xml file from app. server I use open dataset... read dataset. In loop section I remove '#' char. How do You upload xml file from app server? What Could be incorrect.
I try to open dataset in binary mode, text mode...
TYPES: BEGIN OF xml_line,
        data(255) TYPE c,
      END OF xml_line.
DATA: gt_xml_table TYPE TABLE OF xml_line,
      gs_xml_structure TYPE xml_line,
      gv_xml_table_size TYPE i.
OPEN DATASET s FOR INPUT IN BINARY MODE.
IF sy-subrc <> 0.
    MESSAGE e001(zet) WITH '....'.
ENDIF.
DO.
    READ DATASET s INTO gs_xml_structure.
    IF sy-subrc <> 0.
      EXIT.
    ELSE.
     len = STRLEN( gs_xml_structure ).
     len = len - 1.
     check len > 0.
     WRITE gs_xml_structure(len) TO gs_xml_structure.
      APPEND gs_xml_structure TO gt_xml_table.
    ENDIF.
ENDDO.

You Can do this too
parameters: p_file like rlgrap-filename.
data: subrc like sy-subrc.
create object me.
REFRESH t_data.
* Open XML File
CALL METHOD me->CREATE_WITH_FILE
    EXPORTING
      filename = p_file
    RECEIVING
      retcode = subrc.
* Saves Data in an itab from XML File.
CALL METHOD me->get_data
    IMPORTING
      retcode    = subrc
    CHANGING
      dataobject = t_data[].

Create XML file on application server (unix directory) from internal table

Hallo everybody,
I have got the following problem:
I am working with <u><b>release 4.6C</b></u> and have got to create XML files from HR master data and organizational data respectively.
This takes place in 3 steps:
1.     Collect the data in an internal table
2.     Convert the data to XML format using the function module 'SAP_CONVERT_TO_XML_FORMAT'
3.     Download the data
If I download the converted data, which are in an internal table, to the presentation server via the function module WS_DOWNLOAD and open it with the Internet Explorer, everything is ok.
If I download the converted data to the application server, i.e. into a unix directory via
open dataset, loop at internal table, transfer working area to file, close dataset
and then try to open it, this is not possible, because after the last tag some unreadable characters, e.g. a square, appear that arent supposed to be there. Thats what my colleagues told me, for I havent got access to the server.
I have no idea where these characters come from and how I can get rid of them. I guess that either I have to modify (how?) the table with the converted data before the download or I have to use another way to convert the data. For the second way I would probably have to work with an XML class or an XML interface. Unfortunately II am not an expert in working with classes so sample coding would have to be rather detailed.
Heres some more information about how I work with the conversion function module:
call function 'SAP_CONVERT_TO_XML_FORMAT'
       exporting
            i_field_seperator    = lv_field_seperator
           i_line_header        = lv_line_header
           i_filename           = lv_xml_file
           i_appl_keep          = ' '
            i_xml_doc_name       = lv_xml_doc_name
       importing
            pe_bin_filesize      = lv_result
       tables
            i_tab_sap_data       = gt_data
       changing
            i_tab_converted_data = lt_tab_converted_data
       exceptions
            conversion_failed    = 1
            others               = 2.
lv_field_seperator = X.
lv_xml_doc_name = Personalstammdaten Publikation
lv_result: type i
gt_data: fields: PERNR, PERSG, PERSK etc.
types:
begin of truxs_xml_line,
    data(256) type x,
end of truxs_xml_line.
types:
truxs_xml_table type table of truxs_xml_line.
data:
lv_tab_converted_data type truxs_xml_line,
lt_tab_converted_data type truxs_xml_table
open dataset lv_xml_file for output in binary mode.
loop at lt_tab_converted_data into lv_tab_converted_data.
transfer lv_tab_converted_data to lv_xml_file.
endloop.
close dataset lv_xml_file
lv_xml_file: /usr/users/.../.../Personendaten_2004-11-02.xml
Hope the information is detailed enough! Otherwise let me know. Thank you in advance.

Hi Raja,
tried the "TEXT" mode, but that didn't help.
There are still characters after the last tag, that are not supposed to be there including a date that is not
the creation date of the file.
Thank you for your help.

Johannes
