but now,we using ecc6.0.
the problem is : 'utf-8' we down txt(Encoding:UTF-8),But we have a system using VB develop,

I wants to direct down 'GB2312' to system(VB),
who can help me? thank you very much!!!

My iphoto9 has not been able to open for over 10 days!! I can't load my Christmas pics, etc. I know the pics are still there because I can access them through a round about way. Can anyone help me to OPEN iPHOTO!?
To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store or have a Recent Mac you can find it in your Purchases List. -
Getting 'Invalid argument' error while uisng OPEN DATASET. Help!
Hi Experts,
I am trying to read a file from a shared server location using OPEN DATASET as shown below.
OPEN DATASET file_name FOR INPUT IN TEXT MODE ENCODING UTF-8 MESSAGE msg.
The file_name i gave is '
CNSGN-PRE-DM.COM\FUNCTIONAL\INVENTORY.CSV'.
The program compiles perfectly. But when I run the program I am getting 'Invalid argument' error. I have checked the authorization to the server, file name, file availability and everything is fine.
Strangely this code was working fine a week ago.
What could be the problem? Kindly help me!
Thanks
GopalHi Chndrasekhar,
You mean to say the we cannot use OPEN DATASET for reading file in shared server location. For example a shared folder in my PC.
Is there something wrong in the file name path I have given? It started with '//'. Do I have to start the file path wih 'file://..'?
Thanks

Not able to open Dataset when adding Encoding Default
Hi Experts,
I have an urgent requirement . I wanted to make one programs Unicode Complaint
I had to change the statement
open dataset gv_string in text mode for output.
to
open dataset gv_string in text mode encoding default for output.
But after this change the sy-subrc is becoming 8 and not able to open the .Can any one please help
Thanks
ArshadHI,
Maybe there is no authorization for you to write the file onto the app.server.
Check with basis about your authorizations.
Or could be the directory does not exist.

Subramanian
Edited by: Subramanian PL on Jun 27, 2008 1:24 AM -
Hi everyone,
I question about the application server and return sy-subrc from OPEN DATASET.
If i use the SAP Server as Unix, my subrc is 0 and my file is save with successful.
But when we try to save in non-SAP Application Server or anyone shared computer the sy-subrc is 0,
but the file is not generate.
Help description:

We've supposed that our problem is not a authority problem.

Alexandrehi check this..

Maximum length of field in OPEN DATASET
Hello,
I try to import a file from server (for test purposes downloaded on the server directory with transaction CG3Z in ASC) with an unknown length of lines.
Here is my coding for the import into ABAP:
OPEN DATASET p_pa_snam FOR INPUT IN TEXT MODE .
IF sy-subrc NE 0.
ELSE.
DO.
READ DATASET p_pa_snam INTO g_file.
IF sy-subrc NE 0.
EXIT.
ENDIF.
IF NOT g_file IS INITIAL.
SPLIT g_file AT p_pa_sep INTO
wa_textfile_a-textid
wa_textfile_a-langu
wa_textfile_a-textname
wa_textfile_a-textobj
wa_textfile_a-text.
APPEND wa_textfile_a TO zs_textfile_a.
CLEAR wa_textfile_a.
ENDIF.
ENDDO.
So you see that I move the lines from the file to g_file which is of type STRING.
In the import wa_textfile_a the field text is of type STRING too to receive the rest after splitting at the separator into the other fields.
I would expect that this element g_file is a long one which could store my lines from the loaded file,
which could have possibly a length of 5000 digits and more.
Currently I stuck in this step with a length of 217 (!!!) digits in g_file, when importing longer lines (in test I had a line of more than 600 digits.
Is there any idea, what is wrong here or can anyone from you tell me about limitations?
Your help is really appreciated!
Best regards
DirkHello Micky,
you are right!
I checked it by using CG3Y!
Ok, so we will move the file to the server via another solution!
Oh, in my thread above there is a mistyping, 257 instead of 217!
The last digit maybe is from wrong counting! But I won´t count that again!
Best regards
Dirk

Bad data added in Open Dataset for output in Binary mode
Hello,
I am getting random bad data being added to the end of the file that is created on the file server when I run the Open Dataset for output in Binary mode. This data sometimes looks like information about the Unix file server. If I do the Open Dataset in Text mode, it does not add the extra bad data.
** transfer file to Unix File server
DATA: LIN TYPE P.
OPEN DATASET P_APPFIL FOR OUTPUT IN BINARY MODE.
DESCRIBE TABLE XML_TAB LINES LIN.
IF LIN EQ 0.
EXIT.
ELSE.
LOOP AT XML_TAB.
TRANSFER XML_TAB TO P_APPFIL.
ENDLOOP.
ENDIF.
CLOSE DATASET P_APPFIL.
Running the program 2 times with the same variant will give different results.
For example, the data in file should end with </cPedigreeXML> but it added data as shown below:
</cPedigreeXML>8 I X-UNKNOWN 9 I X-UNKNOWN 10
C X-UNKNOWN
Then, when the program was run again with the same selections, it did not add the erroneous data at the end.
This is a real problem because the bad data that gets added causes the file to error in the application. Any help would be greatly appreciated.
Thanks,
BobHi Bob,
Use CLEAR statement after TRANSFER statement and check once.
IF LIN EQ 0.
EXIT.
ELSE.
LOOP AT XML_TAB.
TRANSFER XML_TAB TO P_APPFIL.
<b>CLEAR XML_TAB.</b>
ENDLOOP.
ENDIF.

OPEN DATASET... in a Unicode system
I'm discussing with a developer @ SAP about the correct use of OPEN DATASET in a Unicode system. I'm not sure I'm correct with my opinion so maybe someone could shed a light on it.
The source of discussion is the (SAP standard) program RSQUEU01. This program is used to download data from the TemSE; in our case we use it to produce a file that is to be sent to auditors (component FI-AIS).
Our system is a little endian Unicode system (codpage 4103). If we download the created data using that program we get a dump with "CONVT_CODEPAGE" because a character could not be converted from 4103 to 1100.
The proposed correction by the developer is changing
OPEN DATASET EXP_FILENAME FOR OUTPUT IN legacy BINARY MODE.
to
OPEN DATASET exp_filename
FOR OUTPUT IN LEGACY BINARY MODE
IGNORING CONVERSION ERRORS.
I think, that correction is wrong. Since we have 12 languages in the system including some Asian the output might get corrupted.
When I asked him about that I was told use an application server with a "correct codepage" then - I'm not sure what that means since I can't connect an ASCII application server to a Unicode system.
I guess the statement should be
OPEN DATASET EXP_FILENAME FOR OUTPUT IN BINARY MODE ENCODING DEFAULT.
This makes sure that no data is cut (like doublebyte) and makes sure, the appropriate codepage (LE/BE) is used.
Are my assumptions right?
Markus
(OSS 323320/2010)Hi Markus,
Let's first clarify the difference ways for writing files:
<ul style="list-style:circle!important;">
<li>BINARY MODE: Means that we essentially dump a sequence of bytes, which isn't necessarily related to any code page (and characters). I.e. if I'd want to save for example an executable program, the individual bytes have no meaning when interpreted as characters (unless we look at strings stored in the program). Note that legacy binary mode actually allows you to specify a code page though, but in general the recommendation is not to use the legacy option.</li>
<li>TEXT MODE: Here we have text information that has to be interpreted using a specific code page; thus usually the additional parameter ENCODING should be given, which specifies which code page is used.</li>
</ul>
Now, let's clear up a small typo in Ajay's response:
Yes you are right if you want to have all double byte characters too then you need to use ENCODING DEFAULT which would use 4103 in Unicode system.
That is incorrect. In a Unicode system [encoding default|http://help.sap.com/abapdocu_70/en/ABAPOPEN_DATASET_ENCODING.htm] corresponds to UTF-8, not UTF-16.
Back to your problem. Your suggestion doesn't work, because you cannot specify encoding default for a binary output (the legacy binary mode allows you to specify a code page, but that's misleading and I wouldn't use any legacy mode). So when you try to use the syntax you proposed, you'd get a syntax error.
Generally the recommendation is for Unicode enabled applications to use UTF-8 files with byte order mark, i.e. something like
open dataset EXP_FILE in text mode encoding utf-8 with byte-order mark.
However, the real question is what your external audit application expects and it sounds as if it's not Unicode enabled...
Enough blabber, here's what I'd do: Since you're having issues with a audit-related standard SAP program I'd post the question in forum - other people must have run into that problem. Also, I checked OSS, but couldn't make much sense out of the few notes I've found (and nothing seemed relevant). Check what the expected input format is in the external audit system; possibly post a message to OSS.
Cheers, harald -
Open dataset and close dataset
Hi
I need to write log file in fileshare.
I am using the following FM to create the file.
Z_FILE_OPEN_OUT_UNICODE'
I have following qns
1. do i need to use open dataset and close dataset stmts, even I create the files with the FM?Hi,
you can fill in the name of the FM in transaction SE37, then click 'Display' and look at the source code and the 'Tables' tab.
It's a custom build FM, so you might have to look at the import parameters it needs... ( Tab 'Import' and 'Tables' ).
To answer your question, as the name of the FM suggests it will write the file for you, so no open/close dataset. Please doublecheck tab 'Source code' and you might find these statements there...
hope that helps,

OPEN Dataset - Peculiar problem
Hello experts!
I am facing a peculiar problem with ABAP keyword OPEN DATASET.
I have a directory to which I am adding new files using OPEN DATASET FOR OUTPUT.. this works perfectly fine in the Consolidation system. But the same thing does'nt work in the Production system! It return SY-SUBRC = 8
After reading several other posts on SDN and other forums, the following causes were touted.
1) Path incorrect
2) No Authorization
But upon checking, neither of the wo are possible because the path is maintained properly and the authorizations at OS level are given (R/W) to this folder. Moreover, the user has S_DATASET auth object!!
Then I read somewhere else that having multiple Application Servers could be a possible cause and that running the code as a background job would be afix.. Is it so?
Even if it is, the application is in ABAP Web Dynpro and is launched from the portal.. hence launching it as a background job is not an option... Any solutions?????
Any help on this would be appreciated...
Thanks in advance, AmithHi,
Yes this is true that if we are having the multiple application server then this kind of error occures if your specified directory is not mapped on the alll the avaiable sAP application servers.
I guess when ever you are running your application then system will pick the appkication server based on the present load. Hence if your directory is not mapped in that application server then you wil get this kind of issues,
so i guess check with you basis team that spctified path is avaiable in all the application server. -
OPEN DATASET FOR OUTPUT IN LEGACY TEXT MODE not working!
Hi All,
I need your expertise to help me with my problem.
The program passed through the code OPEN DATASET ... FOR OUTPUT IN LEGACY TEXT MODE. Then it gave an error message "Error Accessing File /home/sap/sample.txt".

What command I should give here
Error analysis
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_TOO_MANY_FILES', was not
caught and
therefore caused a runtime error.
The reason for the exception is:
The maximum number of open files (100) has been exceeded.
please let me know what should makes changes to avoid this abend?Standard programming problem, should be rather trivial to find with a quick search. Basically there's always a limit of how many open file handles you can have at a time.
Please try to consult the ABAP help next time before posting (or search on SCN). A quick check for [open dataset|http://help.sap.com/abapdocu_70/en/ABAPOPEN_DATASET.htm] would've told you the following:
You can open up to 100 files per internal session. The actual maximum number of simultaneously open files may be less, depending on the platform.
Most likely you actually don't want to have all those files open at the same time and you simply forgot to use a [close dataset|http://help.sap.com/abapdocu_70/en/ABAPCLOSE_DATASET.htm] after reading each file.
