Problem in DSO activation - Unicode characters
Hi all,
I am loading data to a DSO from a 02 extractor. I have the transformation in which i have a field routine for product description, which basically converts lower case to upper case, as the product description characteristic in the target accepts only upper case characters. When i loaded data in the production system, i was able to load data into the DSO, but was not able to activate it.
The error i get is
Value ' <Chinese characters>' (hex 'XXXX) of characteristic 0BBP_UCPROD not valid
Error while assigning SID : Action VAL_SID_CONVERT
I think the problem is with the conversion of these two byte characteristics. Can you please suggest a work around ?
Regards
snehith
go to /nrskc and set the value to ALL_CAPITAL_PLUS_HEX
and
Infoobjects texts accept ANY CHARACTERS regardless of any settings..that include chinese..
use literal data in infoobjects texts instead of characteristic values whenever possible and acceptable.
Itu2019ll relieve you from many problems with data loading.

BI Dev client inactive & DSO activation problem
Hi SAP Experts,
Am facing some problems in DSO activation. Firstly the Business content DSO was not activating .So I had to activate the Datasources on the R/3. There were no errors in the job log but the DSO was still inactive. On trying to manually activate it , its stated that the BI Dev client was inactive. So I went to the Source Sytems tab, activated the BI client but it failed showing the following error messages:
1.EDI:Partner profile not available-> A partner profile could not be found with the following key:/IBDCLNT010/LS/
This involves the key fields of the table EDPP1: PARNUM.PARTYP
2.Entry in outbound table not found-> A partner profile could not be found with the following key:/IBDCLNT010/LS/RSRQST///
This involves the key fields of the table EDP13:RCVPRN,RCVPRN,RCVPFC
3.Entry in inbound table not found........LS/RSINFO :
4.Similar to error 3 :...../LS/RSSEND
5.Destination IBDCLNT010 has incorrect Unicode settings,adjust it to destination:
The unicode settings do not match the source systems.Conversion errors might occur during data transfer.Adjust the destination accordingly.
Has anybody seen this error log before. If so please do let me know your valuable suggestions.
Thanks for taking the time to read this technical concern
Edited by: Prathibha Pillai on Jul 29, 2008 7:58 AMHi,
As of 1-4 error messages.
You must define in partner profiles (ts WE20) the message type RSRQST as outbound on BI side and inbound on R/3 side, the message types RSINFO, RSSEND as inbound on BI side and outbound on R/3 side.

DSO activation problem after creating the secondary indexes
Hi,
I am facing the problem with DSO activation after creating the secondary indexes.
Compared with Info Cubes there is no functionality available which allows dropping and recreating a secondary index before/after the data activation.
As a workaround I can write a simple report which drops and creates the indexes on database level.
By using a process chain, we can simply insert the drop index report before data activation and the create index report after the data activation process.
Can any body help me step by step procedure or Material to write the programs for delete index and create index reports on DSO object?..
Thanks in advance for your help.
Thanks & Regards,
Balahi,
in BI if you are using the dso for reporting then you can simply chk the settings of dso for SID generation.
no need to create the indexes or delete it.
if the dso is not used for report then no need to use indexes.

Problems reading unicode characters with BufferedReader or PrintWriter
I am creating a pretty standard chat server and client with the exception that I want to be able to send special math symbols back and forth to aid in helping people with math homework. The unicode characters will appear on the buttons, in the textField (where users type in their messages), in the messageArea (where users see all of the messages) correctly. However, as soon as the server reads it, it is converted to a ? character by either the BufferedReader or the PrintWriter, but I am fairly certain it is the BufferedReader. All of the Sun examples I have read recommend doing exactly what I have done to be able to support unicode characters so I am somewhat at a loss. Any help would be appreciated. I will include all of the source code (which is rather large) but the main problem is the with the BufferedReader or PrintWriter when the servers reads the string in and then broadcasts it to all the clients (at least I'm pretty sure it is).

But in your case, I think that none of the 1000 lines of code you posted are the problem. You appear to be using Lucida Sans, which is a positive sign; it can render many of the characters you have hard-coded in your program. But apparently the problem is with characters that are coming from somewhere else? And you are using a PrintWriter to send them there and a BufferedReader to get them back? These convert your data from characters to bytes and back again using the default encoding for your system. Chances are that this encoding is some "extended ASCII" encoding that doesn't know how to map anything above \u00ff. You need to get an InputStreamReader and an OutputStreamWriter into your transmission. (Wrap your socket.getInputStream() in an InputStreamReader and wrap that in a BufferedReader, etc.) These objects can take an encoding name as their second parameter; try "UTF-8" or "UTF8" for the encoding. Their API documentation has a link to a page about encodings; follow that if you need more info. -
Errors found by DSO activation
Hi gurus,
i got the following errors after checking the logs of the DSO activation. Any suggestions??
Thanks. points will be given,
SD
Value " " from characteristic ZM_RMTEXT contains an error at position 1
Message no. BRAIN290
Diagnosis
Characters that have a hexadecimal display between HEX00 and HEX1F are not permitted in characteristic values. The character at position 1 is one of these characters. The value is therefore not permitted.
Note that these characters cannot be displayed and are therefore displayed as '#'. The actual character '#' has the hexadecimal display HEX23.
Procedure
Check the origin of the characteristic value. If possible, change the characteristic value in the source.
Incorrect source text in update routines and transfer routines can also cause this problem.
============================================================================
Value 'B2 1234567 Kabelsatz' (hex. '4232203132333435363720204B6162656C7361747A') of characteristic ZM_MATTAU contains invalid characters
Message no. BRAIN060
Diagnosis
Only the following standard characters are valid in characteristic values by default:
!"%&''()*+,-./:;<=>?_0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ.
Furthermore, characteristic values that only consist of the character # or that begin with ! are not valid.
You are trying to load the invalid characteristic value 1. (hexidecimal representation 4232203132333435363720204B6162656C7361747A).
Procedure for System Administration
Try to change the invalid characters to valid characters.
If you want values that contain invalid characters to be admitted into the system, make the appropriate setting in BW Customizing. Refer to the documentation describing the requirements for special characters and the possible consequences.
For more information on the problems involved with valid and invalid characters, click here.Hi,
You have invalid characters for the field ZM_MATTAU. Due to these your DSO activation is failing.
The way to resolve this is to write a cleansing routine for that field to strip away the bad characters and only permit the good characters to go through.
If you search the forum you'll get sample codes for the same.
Cheers,

CRVS2010 Beta - Cannot export report to PDF with unicode characters
My report has some unicode data (Chinese), it can be previewed properly in the windows form report viewer. However, if I export the report document to PDF file, the unicode characters in exported file are all displayed as a square.
In the version of Crystal Report 2008 R2, it can export the Chinese characters to PDF when I select a Chinese font in report. But VS2010 beta cannot export the Chinese characters even a Chinese font is selected.Barry, what is the specific font you are using?
The below is a reformatted response from Program Management:
Using non-Chinese font with Unicode characters (Chinese) the issue is reproducible when using Arial font in Unicode characters field. After changing the Unicode character to Simsun (A Chinese font named 宋体 in report), the problem is solved in Cortez and CR both.

I go to BW1CLNT100 datasoucres ,I not finded 80FIAP_O03 datasoucre, But I goto bw prd BI datasoucre, I found 80FIAP_O03 datasoucre.
I think loss 80FIAP_O03 datasoucre for BW1CLNT100 source system, because I am't delete Roules on the 0FIAP_O03 infosoucre for delete sap soucre systems.
DSO Activation Error - While Installing BI Content
this problem no issue, So I create new thread.
Now, How could me create or load 80FIAP_O03 datasoucre for BW1CLNT100 source system?
Now, I Replicate Datascoure for BW1CLNT100 source system, Delete old datasocure....... I go home, I will try tomorrow .Hello,
You should generate the export data source for 0FIAP_O03 again, if there is still a problem please goto
RSA1 > SOURCE SYSTEMS > and right click on the relevant source system, find the datamart application component and
right click on this to replicate the datasource.
Best Regards,

I have a standard DSO. In the settings, the only thing checked is "Set Quality Status to 'OK' Automatically", I have this loading using a process chain and in the chain, I have the Activate process included.
The DSO loads with no problem, but the Activate step fails with error message "No active PSA table".
Two things that seem weird:
1. Without doing anything, I go to the DSO > Manage and the DSO has been activated (so why does the process Activate in the process chain fail?)
2. If I Repeat the Activate step in the process chain, even though the process is active based on # 1 above, the Activate step turns green and completes the process chain.
I am having this problem for several DSOs in several different chains.
Thanks for any help. Keith JPC- Display variant for DSO activation - click on Parallel processing - click DS Activ option -
Background with "A"
Num of Par proessing = 6
again Click on this time DS-SID GEN
Background with "C"
Num of Par proessing = 3
Make sure you have the same settings for DSO activation which are failing?
Also refer Note: 1301094 - SP21:Error during activation of DSO in a Process Chain
Symptom
When you execute a DTP for loading a Datastore Object error happens in the activation of Datastore. This typically happens in a process chain. The error messages are as follows:
o RSDRO 103: "PSA update failed"
o RSAODS 003: "Error occurred while deciding partition number"

Insert Unicode Characters Into Oracle 8.1.5
Hello,
First off, here are the specs:
Oracle 8.1.5
JDK 1.2.1
Oracle8i 8.1.6.2.0 JDBC Drivers for use with JDK 1.2.x for Solaris
I'm running into a problem with insert Unicode characters into Oracle via the JDBC driver. As you can see above, I am using the Oracle 8.1.6.2.0 JDBC driver because it is the first driver with supports the JDK 1.2.x. So I think I should be okay.
I can retrieve data with special characters from Oracle by calling the getBytes() method from the ResultSet with all special characters being intact. I am using getBytes because calling getString() would throw the following exception: "java.sql.SQLException(): Fail to convert between UTF8 and UCS2: failUTF8Conv". However, with that value that I just retrieved, or any other data with special characters (unicode) in which I try to insert into Oracle does not get converted properly.
What appears to be happening is that data with special characters (unicode), are not being treated as a single double byte character, but rather two single byte characters. Thus, R|ckschlagventil becomes RC<ckschlagventil once it is inserted. (Hopefully, my example will be rendered properly).
According to all documentation that I have found, the JDBC driver should not have any problem with converting UCS2 Java Strings to Oracle's UTF8 character set.
I have set Oracle's NLS_NCHAR_CHARACTERSET to UTF8. I am also setting the environment variable NLS_LANG to AMERICAN_AMERICA.UTF8. Perhaps there is some other environment setting in which I am missing?
Any help would be appreciated,
Christian
nullImport has a lot of options, so it depends on what you want to do.
C:\> imp help=y
will show you all possible options. An example of full import :
C:\> imp <username>/<password>@<TNS alias> file=<DMP file> full=y log=<LOG file>

Scanning files for non-unicode characters.
Question: I have a web application that allows users to take data, enter it into a webapp, and generate an xml file on the servers filesystem containing the entered data. The code to this application cannot be altered (outside vendor). I have a second webapp, written by yours truly, that has to parse through these xml files to build a dataset used elsewhere.
Unfortunately I'm having a serious problem. Many of the web applications users are apparently cutting and pasting their information from other sources (frequently MS Word) and in the process are embedding non-unicode characters in the XML files. When my application attempts to open these files (using DocumentBuilder), I get a SAXParseException "Document root element is missing".
I'm sure others have run into this sort of thing, so I'm trying to figure out the best way to tackle this problem. Obviously I'm going to have to start pre-scanning the files for invalid characters, but finding an efficient method for doing so has proven to be a challenge. I can load the file into a String array and search it character per character, but that is both extremely slow (we're talking thousands of LONG XML files), and would require that I predefine the invalid characters (so anything new would slip through).
I'm hoping there's a faster, easier way to do this that I'm just not familiar with or have found elsewhere.require that I predefine the invalid charactersThis isn't hard to do and it isn't subject to change. The XML recommendation tells you here exactly what characters are valid in XML documents.
However if your problems extend to the sort of case where users paste code including the "&" character into a text node without escaping it properly, or they drop in MS Word "smart quotes" in the incorrect encoding, then I think you'll just have to face up to the fact that allowing naive users to generate uncontrolled wannabe-XML documents is not really a viable idea. -
The JSP WYSIWYG Editor can't display most Unicode characters
Eclipse supports display of Unicode characters very well since version 3. However, NitroX couldn't display most most of them. Well, besides characters from other non-Western European languages, NitroX can't even display characters that it's supposed to support. Well, that's what I think so. I mean, when we type the & character, we have the whole list of character entity references amongst which we could find ∧ ∇ ∨ → but which are not displayed correctly. And many more are in this case.
Is this a feature or a bug? By "feature", it means that we can't get them in free version.I have exactly the same problem. I support web pages for 25 European countries. I've not seen Nitrox support any unicode characters. Until M7 answers this question or fixes the editor, you can use the Eclipse editor to see and edit the text.

Direct Execution of query having Unicode Characters
Direct Execution of query having Unicode Characters
Hi All,
In my application I am firing a Select Query having Unicode characters in Where Clause under condition like '%%'
to Oracle 10g DB from a Interface written in VC6.0...

You were bang on target...
Though it took some time for me to resolve the issue...
to use SQLExecDirectW I need my query in SQLWCHAR *, which is stored in char * in my case...
So i converted the incoming query using MultibyteToWideChar Conversion with CodePage as CP_UTF8 and
then passed it on to SQLExecDirectW...
It solved my problem
Thanks,
Pratik...

Problem convertting certain extended ascii characters
I'm having problems with the extended ascii characters in the range 128-159. I'm working with SQL server environment using java. I originally had problems with characters in the range 128-159 when I did a 'select char_col from my_table' I always get junk when I try to retreive it from the ResultSet using the code 'String str = rs.getString(1)'. For example char_col would have the ascii character (in hex) '0x83' but when I retrieved it from the database, my str equaled '0x192'. I'm aware there is a gap in the range 128-159 in ISO-8859-1 charset. I've tracked the problem to be a charset issue converting the extended ascii characters in ISO-8859-1 into java's unicode charset.
I looked on the forum and it said to try to specify the charset when I retreived it from the resultset so I did 'String str = new String(rs.getBytes(), "ISO-8859-1")' and it was able to read the characters 128-159 correctly except for five characters (129, 141, 143, 144, 157). These characters always returned the character 63 or 0x3f. Does anyone who what's happening here? How come these characters didn't work? Is there a workaround this? I need to use only use java and its default charsets and I don't want to switch to the windows Cp1252 charset cuz I'm using the java code in a unix environment as well.
thanks.
-BNormally your JDBC driver should understand the charset used in the database, and it should use that charset to produce a correct value for the result of getString(). However it does sometimes happen that the database is created by programs in some other language that ignore the database's charset and do their own encoding, bypassing the database's facilities. It is often difficult to deal with that problem, because the custodians of those other programs don't have a problem, everything is consistent for them, and they will not allow you to "repair" the database.
I don't mean to say that really is your problem, it is a possibility though. You are using an SQL Server JDBC driver, aren't you? Does its connection URL allow you to specify the charset? If so, try specifying that SQL-Latin1 thing and see if it works. -
Unicode characters not displayed in text property
I am developing a web application with Flex Builder. I write
the text for each label using a font called Dhivehi which is
written from left to right, and then copy the text and paste it in
the label property called text.
However in the source code view the text property of the
label shows
text=""
The issue is that when rendered the text is rversed. So I
want to run a function once the application is loaded, to reverse
the text in the label, so that the text will appear in it's
original way.
any help will be very much appreciatedHi,
I have a strange problem here with Windows.Forms.RichTextBox, when I assign a .ToString() value of sting builder to a rich text box’s .Rtf Property the Unicode characters containing in string builder gets converted to ???? symbols in .Rtf property of rich
text box.
Could you please let me know if Rich text box’s .Rtf property can hold Unicode characters? or is there any other way to store the Unicode characters in rich text box?
Thanks & Regards,
Tabarak
Hello,
To clarify and help you get proper solution, I would recommend you share a rtf string or even a simple sample which could reproduce that issue with us.
We will based on that sample to help you.

What table column size is needed to accomodate Unicode characters
Hi guys,
I have encounter something which i dont understand and i hope gurus here will shed some light on me.
I am running a non-unicode database and i decided to port the data over to a unicode database.
So
1) i export the schema out --> data.dmp
2) then i create the unicode database + create a user
3) then i import the schema into the database
during the imp i can see that character conversion will take place.
During importing of data into the unicode database
I encounter some error
saying column size is too small
so i went to check the row that has the column value that is too large to fit in the table.
I realise it has some [][][][] data.. so i went to the live non-unicode database and find the row. Indeed it has some [][][][] rubbish data which i feel that someone has inserted other language then english into the database.
But regardless,
I went to modify the column size to a larger size, now the row can be accommodated. However the data is still [][][].
q1) why so ? since now my database is unicode, during the import, this column data [][][] should be converted to unicode already but i still have problem seeing what language it is.
q2) why at the non-unicode database, the [][][] data can fit into the table column size, but on unicode database, the same table column size need to be increase ?
q3) while doing more research on unicode, it was said that unicode character takes up 2 byte per character. Alot of my table data are exactly the same size of the table column size.
E.g Name VARCHAR2(5);
value - 'Peter'
Now if converting to unicode, characters will take 2byte instead of 1, isnt 'PETER' going to take up 10byte ( 2 byte per character ),
why is it that i can still accomodate the data into the table column ?
q4) now with unicode database up, i will be supporting different language characters around the world. How big should i set my column size to ? the longest a name can get ? or ?
Thanks guys!/// does oracle automatically "look" at the each and individual characters in a word and determine how much byte it should take.
Characters usually originate from a keyboard, which has an associated keyboard layout and an associated character set encoding (a.k.a code page, a.k.a. encoding). This means, the keyboard driver knows that when a key with a letter "á" on it is pressed on a French keyboard, and the associated character set encoding is MS Code Page 1252 (Oracle name WE8MSWIN1252), then one byte with the value 225 is generated. If the associated character set encoding is UTF-16LE (standard internal Windows encoding), two bytes 225 and 0 are generated. When the generated bytes travel through APIs, they may undergo character set conversions from one encoding to another encoding. The conversion algorithms use translation tables to find out how to translate given byte sequence from one encoding to another encoding. In case of translation from WE8MSWIN1252 to AL32UTF8, Oracle will know that the byte sequence resulting from conversion of the code 225 should be 195 followed by 161. For a Chinese characters, for example when converting it from ZHS16GBK, Oracle knows the resulting sequence as well, and this sequence is usually 3 bytes.
This is how AL32UTF8 data gets into a database. Now, when Oracle processes a multibyte string, and needs to look at individual characters, for example to count them with LENGTH, or take a substring with SUBSTR, it uses information it has about the structure of the character set. Multibyte character sets are of two type: fixed-width and variable-width. Currently, Oracle supports only one fixed-width multibyte character set in the database: AL16UTF16, which is Oracle's name for Unicode UTF-16BE encoding. It supports this character set for NCHAR/NVARCHAR2/NCLOB data types only. This character set uses two bytes per each character code. To find the next code, 2 is simply added to the string pointer.
All other Oracle multibyte character sets are variable-width character sets, including AL32UTF8. In most cases, the length of each character code can be determined by looking at its first byte. In AL32UTF8, the number of 1-bits in the most significant positions in the first byte before the first 0-bit tells how many bytes a character has. 0 such bits means 1 byte (such codes are identical to 7-bit ASCII), 2 such bits mean two bytes, 3 bits mean 3 bytes, 4 bits mean four bytes. 1 bit (e.g. the bit sequence 10) starts each second, third or fourth byte of a code.
In other ASCII-based multibyte character sets, the number of bytes is usually determined by the value range of the first byte. Bytes below 128 means a one-byte code, bytes above 128 begin a two- or three-byte sequence, depending on the range.
There are also EBCDIC-based (mainframe) multibyte character sets, a.k.a shift-sensitive character sets, where a sequence of two-byte codes is introduced by inserting the SO character (code 14=0x0e) and ended by inserting the SI character (code 15=0x0f). There are also character sets, like ISO-2022-JP, which use more complicated byte sequences to define the length and meaning of byte sequences but Oracle supports them only in limited number of places.
/// e.g i have a word with 4 character. the 3rd character will be a chinese character..the rest are ascii character
/// will oracle use 4 byte per character regardless its ascii(english) or chinese
No.
/// or it will use 1 byte per english character then 3 byte for the chinese character ? e.g.total - 6 bytes taken
It will use 6 bytes.
Thnx,
Sergiusz
