Error during Unicode Conversion - Import

Hi,
I am doing a Unicode conversion, done with the system export, while doing the
import during the Import ABAP phase system is throwing the error with R3load.
R3load -testconnect fails with following error.

  • Error during unicode conversion

    Dear all,
    we are facing one issue during unicode conversion. the code is as follows:
    FIELD-SYMBOLS : <n> TYPE X,
                                 <c> TYPE C.
    DATA : a TYPE i.
    DATA : x TYPE x.
    MOVE <n> TO a.
    a = a + 22.
    MOVE a TO x.
    ASSIGN x TO <c> CASTING TYPE c
    and we are getting the following error:
    ERROR : the length of "X" in bytes must be a multiple of the size of a Unicode character (regardless of the size of the unicode character
    please guide on how this can be resolved in ECC.
    Regards,

    Hello,
    I recently experienced this problem, and it seems that when executing this step the <sid>adm account needs to be defined to use C shell.  If its already set up to use C shell, check the <sid>adm logon scripts to make sure all the environment variables are being set correctly.

  • Error during Unicode Conversion at DDNTF table

    Hello
    We are doing a Unicode Conversion for our CRT systems. This system now
    is a SAP CRM 7.0 SR1 ABAP.
    We have performed preparatory steps (SPUMG, checks, updating R3load,
    R3ldctl, R3szchk, dboralib, ...),
    but when we start Import process we get an error in SAPSDIC package.
    The error looks like:

    Any idea??

    Yes I executed this Report using Menu Tool Bar.
    The first execution gave me some errors regarding some tables existing at database level but  not in DDIC. We ignored this errrors because those tables are not important.
    But the last try, we decided solve this inconsistencies deleteting those tables at database level, repeting report RADUCNT (in this case no errors appeared) and repeting the export with the same error..
    Now, we have seen in Tabscript STATUS of SPUMG there are some errors regarding DDNTF inconsistency found at table control. Reason 4.  But this reason means that faillback codepage missing at table control for this table. But as far I know, I can't fill failbak field for this kind of table...
    So know I'm reseting SPUMG, and reestarting again..
    But I don't understand what is the problem
    In a few minutes I will you inform about results
    Meanwhile is anybody have any suggestion or idea... please let me know
    Thanks!

    Hi Volker,
    Thank you very much. Stupid error :-).
    I also did step 2 with fixr3owns yesterday with SAPINST and then it worked. I got to step 3 "iSeries Installation Step", but got an error in SAPINST when "Creating infrastructure for SAP system BND". I logged off SAPINST, patched CRTR3SYS and started SAPINST again and then got the error in step 2 wirh fixr3owns.
    I´m now past step 2 and in step 3 "iSeries Installation Step". And I get the same error as I got yesterday...
    From the job log:

    Hello,
    you need to ensure that the Unicode conversion is done during export (target code page 4102 or 4103).
    This error typically occurs if the export does not include the Unicode conversion (simple system copy with Non-Unicode).

  • R/3 Export & Import during Unicod Conversion via SOCKET Method

    Hi
    We are in the process of upgrading our R/3 Enterprise to ECC 6.0. The size of the database is around 4 TeraBytes.
    Can somebody help us with necessary documentation/ othe rinputs to handle R/3 Export & Import using SOCKET method?  FYI we referred the SAP given doucments on the same. Any particular DOs & DO NOTs would be highly appreciated.
    Thank You
    Sai

    Hi Rahul
    regarding your 'Unicode doubt"' some ideas:
    1) The Upgrade Master Guide SAP ERP 6.0 and the Master Guide SAP ERP 6.0 include introductory information. Among other, these guides reference the SAP Service Marketplace-location http://service.sap.com/unicode@sap.
    2) In Unicode@SAP can you find several (content-mighty) FAQs
    Conclusion from the FAQ: First of all your strategy needs to follow your busienss model (which we can not see from here):
    Example. The "Upgrade to mySAP ERP 2005"-FAQ includes interesting remarks in section "DO CUSTOMERS NEED TO CONVERT TO A UNICODE-COMPLIANT ENVIRONMENT?"
    "...The Unicode conversion depends on the customer situation....
    ... - If your organization runs a single code page system prior to the upgrade to mySAP ERP 2005, then the use of Unicode is not mandatory. ..... However, using Unicode is recommended if the system is deployed globally to facilitate interfaces and connections.
    - If your organization uses Multiple Display Multiple Processing (MDMP) .... the use of Unicode is mandatory for the mySAP ERP 2005 upgrade....."
    In the Technical Unicode FAQ you read under "What are the advantages of Unicode ...", that "Proper usage of JAVA is only possible with Unicode systems (for example, ESS/MSS or interfaces to Enterprise Portal). ....
    => Depending on the fact if your systems support global processes, or depending on your use of Java Applications, your strategy might need to look different
    3) In particular in view of your 3rd option, I recommend you to take a look into these FAQs, if not already done.
    Remark: mySAP ERP 2005 is the former name of the application, which is named SAP ERP 6.0, now
    regards, and HTH, Andreas R

    I did finish all the unicode preconversion steps and also ran the SMIGR_CREATE_DDL program. I had exported recently from the same system but I never got this error during that run.
    Another question is about the order in which the steps need to be performed. I completed the preconversion steps, then ran the SMIGR_CREATE_DDL program before proceeding to the export phase. Is this right or does it not matter?
    Thanks again for your help!

    Hello Stacy,
    > When I run the following command on /BIC/SZTERR_CD, I do not get any table information back. I am not sure how to fix it though.
    > SELECT * FROM DBA_OBJECTS WHERE OBJECT_NAME = '/BIC/SZTERR_CD ';
    If the object does not exists on the source target database, please check if the ddic of sap still contains the table definition. (SE11 or SE14)
    If yes you can set the status of the table /BIC/SZTERR_CD to "ok" in the corresponding task file.
    You can not fix this problem in other way after you have started the conversion, because of the export files are already generated (with the information of the sap ddic)...
    > I completed the preconversion steps, then ran the SMIGR_CREATE_DDL program before proceeding to the export phase. Is this right or does it not matter?
    That was the right way.
    Regards
    Stefan

    We have already read 425079, so, can we use source system layout?
    can SAPinst use our previous tablespace layout during import? ... or do
    we must it manualy?
    Regards.

    Hi,
    >It is far better that you create the target database using the new layout. The old tablespace layout with multiple tablespaces and >data/index separation is no longer adapted to modern environments, and a Unicode conversion gives you a unique opportunity to >switch to a more appropriate structure for your DB.
    So... to do it: I leave standard tablespace (without create my old tablespace PSAPZ*******) and then enlarge enough to load our tables? ... do I modify any other file/script for the import?

  • Performance during Unicode Conversion

    Hello,
    currently we are planning to do a Unicode Conversion on a Linux/MaxDB System.
    The DB has a size of approx. 350 GB. The system runs on Fujitsu-Siemens FlexFrame hardware.
    One problem is that during a test conversion the export of the DB took more than 24 hours.
    This seems too much regarding the DB size.
    We know that filesystem and RAM and CPUs influence the export duration.
    What possibilities do we have to tune the export with "software" tools?
    - table splitting
    For example: Our largest table has ~26GB datasize.
    How do we split this table?
    In 10 parts or in 20 or in 200?
    If you could please post your experiences.
    Regards, Michael

    I don´t wanna discourage you but I´m not sure if splitting that single table will help alot.
    The problem with this combination is the fact, that the MaxDB database reads data block-by-block, means, exeucting single I/Os for each block to read. Given that fact and the fact, that each I/O will be ran over an NFS (with the known latency) it´s unlikely that you will get much more speed out of this.
    The problem is NOT the speed between the NAS and the database server, if you will look on the network traffic you will see, that there´s plenty left. The problem is the latency on the client side (the database server) when you put your files on NFS.
    I can export a 250 GB database in under 3 hours (admittedly - without UC conversion) using a direct fibrechannel connection (so non-NFS) so the database itself is certainly not the problem, it´s the combination of the usage of NFS (no matter if v2 or v3) and the way the MaxDB database reads data.
    I´ve been involved in a likewise project and with a NetApp specialist and some in-depth tuning we were able to gain 15 - 20 % speed but not more.

  • Usage of Conversion Classes During Unicode Conversion

    Hi,
    I have code
    "TRANSLATE  BBKF-SGTXT FROM CODE PAGE '0100' TO '0120'"  Now During Unicode i need to Use the Conversion classes
    Can any one help to proceede further on this
    Actually I am using  CL_ABAP_CONV_OUT_CE and I am getting the Data in Binary Format But I want that to be in Character format can any one suggest me
    Thanks & Regards,
    Prasad

    Do you have an EBCDIC system with code page 0100? (check it using SNLS transaction)
    In that case, CL_ABAP_CONV_OUT_CE is okay.
    After having converted to code page 0120 (into xstring), here is how to cast xstring variable to character.
    DATA x TYPE x LENGTH 800. " so that to compile, x length
                              " must be a multiple of 4 (don't ask why)
    FIELD-SYMBOLS <c> TYPE c.
    x = xstring. "make sure x is long enough
    ASSIGN x TO <c> CASTING.
    BBKF-SGTXT = <c>.

  • Minimize downtime during UNICODE conversion

    Hello forum !
    I am looking at the UNICODE conversion of a large (?) SAP Oracle database for ECC. The Database it self is at about 10 TB. UNICODE converting this in one single run will take too long to fit inside the company defined tolerable downtime window.
    When looking at the data I find that the largest 50 tables makes up about 75% of the total database size. Most of the 50 largest tables have data for several years back, and I am able to partition the tables with one partition pr year.
    The good thing about this is that I am able to make the partitions with old data (more than one year old data) READ-ONLY.
    My assumption is that I will be able to UNICODE convert 60-70% and create the indexes for these partitions without taking down the database to be converted.
    Now,- doing the downtime-phase I will be able to exclude the old partitions of the largest tables in the export since I have already created a new UNICODE database with these objects and thereby drastically reducing the required downtime.
    Is there anyone who has any experience with an approach like the one I have schetched out here ?
    Kjell Erik Furnes

    Can you please be a bit more specific on your installation? How long is your possible downtime (export time should be about 2/3 of that)? How long is your actual export estimation? Do you have suitable hardware (CPU/disk)?
    What you absolutely need to have:
    [1043380 - Efficient Table Splitting for Oracle Databases|https://service.sap.com/sap/support/notes/1043380] -> export tables with ROWID splitting
    [855772 - Distribution Monitor|https://service.sap.com/sap/support/notes/855772] -> enables distributed and parallel export/import
    So on the hardware side you will need, a storage subsystem as fast as possible with two copies of the disks (one for exporting and one for importing). A bunch of application servers with fast CPUs helps a lot, everything connected with at least gigabit ethernet.
    If you knew all this already, sorry for the spam. But i achived throughputs at about 400gb/hour on a medium sized hardware, i think throughputs of 1tb/hour should be possible (not talking about cluster tables

  • Nametab issue during unicode conversion

    There are some tables inconsistent durning Unicode conversion, is it possible to delete them?
    Moderator message: not directly related to ABAP development, please have a look in the Netweaver forums, alway search for information before asking.
    Edited by: Thomas Zloch on Dec 23, 2010 1:32 PM

    Hi,
    Reposting the question again, as earlier one was incomplete.
    We are doing Unicode Conversion activity in one of our system. After running through UCCHECK transaction, we got around 80 programs in which most of them were resolved manually. When we are trying to edit one object, the error"Namespace /OSJ8C/' does not exists is displayd. Any help to resolve this issue will be highly appreciated .
