Problem when creating a collaboration room

Hi there,
I'm trying to create a room using the room creation wizard but got a Portal Runtime error. We are runing SP12 and it's our first time creating a room after installation.
any help is much appreciated..
The followings are errors we found in defaultTrace.trc.
An exception occurred while processing a request for :

  • Problem when creating a sales order with reference by BAPI

    I am facing one problem when creating Sales Order.
    <b>The scenario is like this while creating SO With reference to an Order type, a new SO will be automatically created with a diff order Type</b>.
    I am using "BAPI_SALESORDER_CREATEFROMDAT2".
    I am calling this BAPI in USEREXIT_REFRESH_DOCUMENT.
    Am I using the right exit to call this Bapi ?
    <b>Problems are like :
    1. Ref Sales Order creating without Sales Unit .
    2. "Object Status does not exist" error msg is coming for Header and Item level(when clicking the status tab and then object status pushbutton).</b> But if testing the bapi from SE37 in test sequence....no such problem persists.
    As for example in case of sales unit,in the debugging mode i have seen that BAPI uses a perform to fill the values in the VBAP structure.But after that when it come back to the main program VBAP remains blank.This ocuurs when the BAPI is called from the exit whereas  if tested from SE37, VBAP retains the value.
    Can u suggest in this ? This is very very urgent............
    Thx in Adv.........................

    Thanks........
    Your suggestion was a great help to me.I have used a custom FM and called it in <b>starting new task</b>.
    Since i am a university fresher working in SAP for nearly 1 year.....can you please explain me the difference between <b>in update task</b> and <b>starting new task</b>.Why the problem was occuring for which you have suggested to call a custom function module.
    what is V1 update and V2 update?Is it attached with asynchronous ans synchronous update.It would be a great help to me if you kindly clear my confusions....
    thanks in advance.

  • Problem when creating Database (Database, OS and hardware Configuraiton included)

    Problem when creating Database:
    Below are the problems, which I faced during creation of database. I have mentioned both the problem separately. Plus the log file maintained by Oracle during installation. It might help in diagnosing the error. Plus a little conclusion with I turned up to.
    There are two problems, when creating database with Oracle Database Assistant. One when creating pre tuned database from CD. And second when creating customized database giving options your self.
    Problem # 1:
    When creating pre tuned database from CD. The process of creating Database is 90 % complete and is at step # 3 Initializing Database. It gives error ORA-03113: end-of-file on communication channel.
    I searched following oracle help for this problem.
    ORA-03113: end-of-file on communication channel
    Cause: An unexpected end-of-file was processed on the communication channel. The problem could not be handled by the Net8, two-task software. This message could occur if the shadow two-task process associated with a Net8 connect has terminated abnormally, or if there is a physical failure of the interprocess communication vehicle, that is, the network or server machine went down.
    Action: If this message occurs during a connection attempt, check the setup files for the appropriate Net8 driver and confirm Net8 software is correctly installed on the server. If the message occurs after a connection is well established, and the error is not due to a physical failure, check if a trace file was generated on the server at failure time. Existence of a trace file may suggest an Oracle internal error that requires the assistance of customer support.
    Conclusion:
    What I conceive from this problem and the help available is that, I have to install NET8 again. But I am not sure about the solution, please tell me whether I am rite or not.
    Problem # 2:
    When creating database with custom option. The process of creating Database is 2 % complete and is at step # 2 Creating Database Files. It gives error ORA-12571: TNS:packet writer failure.
    I searched following oracle help for this problem.
    ORA-12571: TNS:packet writer failure
    Cause: An error occurred during a data send.
    Action: Not normally visible to the user. For further details, turn on tracing and re-execute the operation. If error persists, contact Worldwide Customer Support.
    Conclusion:
    What I conceive from this problem and the help available is that, I have to install NET8 again. But I am not sure about the solution, please tell me whether I am rite or not.

    Dont't worry about that. Before you
    create a table(or view), it is wise to
    drop the table(or view) with the same name.
    If the name doesn't exist, of course there
    is an error message. See the following script:
    -------------------begin-----------
    drop table students cascade constraints;
    create table students (
    sid varchar2(5),
    fname varchar2(20),
    lname varchar2(20) not null,
    minit char,
    primary key (sid));

    Good day!

  • Problem when creating CAF Entity Service finder Methods

    Guys,
    Can any one please suggest me appropriatly to the below problem.
    I am using NWDS 7.06. I have no problem when creating CAF project, Application Service and Entity Service even.
    But in the Entity Service:
    1. Add a string or longtext attribute.
    2. try to create a custom finder method in operations tab, during that operation i am  not finding the attribute which i have created in step1.
    That means i am not able to create the my own finder methods with parameters.
    I was able to do that in some version long ago but i have forgotten that NWDS version.
    summary of Problem Is: " Cannot create custom methods with custom parameters in Entity Service"
    Can you please suggest me the right version or a solution to this problem on urgent basis please.
    I promise you that i will give you full points to you who ever gives me the right solution.
    Please mail your suggestions to [email protected]

    Guys,
    I have solved the problem successfully. Thanks for your attention.

  • Problem when Creating Project (Composite Application Services) in NWDS

    I've seen a few posts regarding this but I don't feel as if any real solution was given.
    I just installed Netweaver Developer Studio (7.0.15) with the current JDK/JRE (1.6.0_07).  When trying to create a new Composite Application Services project within the Studio, using the new project wizard, I get an error: Problem when Creating Project.
    I get the EJB Module and Dictionary to create within my navigator with no problems, however, during the creation of the metadata, the error occurs.  I do have the metadata folder appear within the navigator, but nothing in it.  None of the other three items are created.
    I have tried the attempt at deleting the metadata folder within my workspace directory and trying again but the same exact result occurs.
    Is there any other solution out there for this problem besides attempting to find older versions of NWDS, etc. that are more "stable"?
    Thank you!

    Durga,
    Very simple but effective solution.
    I had tried uninstalling / re-installing NWDS with no effect but uninstalling / re-installing NWDS AND all java related products on my machine did work.
    Note: For anyone else with this issue in the future.  I installed the Java SDK / JRE 1.4.2_18 with NWDS 7.0.15 in case this is also a possible issue with versions.
    Thanks, Durga!

  • Problem when creating contract  with foreign trade / customs

    Hi,
    I encountered a problem when creating contract / outline agreement.
    I used ME31K to create a contract with a vendor outside of our country. I suppose that I should be able to see "Foreign Trade / Customs" in "Header" menu, but this entry is gray, I cannot enter it.
    I tried to create a scheduling agreement using ME31L with the same vendor and material, I can see "Foreign Trade / Customs" information. I suppose these two process are similar, aren't they?
    Btw., I checked the master data according to this thread:
    http://help.sap.com/saphelp_46c/helpdata/en/ed/3b6cc697e711d1b4e20000e82d81b0/content.htm
    Can anyone give me some hint?
    Thanks!
    Charlie

    These two processes are different:
    The Contract agreement or the Outline Agreement is that create the centrally contract (cross-plant) where it can maintain different pricing conditions for each and every plant. It creates the Release Order with reference to Outline Agreement. No detailed delivery schedule can be made in the Release Order. No Release documentation is created. Only time-dependent conditions can be created, Some Item Category 'M' and 'W' can be used.
    Whereas the Scheduling Agreement is the Plant Location what must be entered in the Scheduling Agreement. Its no need to create any other purchasing document except for delivery schedule line via Transaction ME38 or MRP running (with the appropriate setting of Source List). Delivery Schedule line items are created subject to your specific requirement. It can create both Scheduling Agreement with or without release of Documentation (subject to the Document Type LP or LPA) with the selection of either FRC or JIT delivery schedule. Either time-dependent or time-independent conditions can be created subject to the customizing in the Document Type of the Scheduling Agreement. Item Category 'M' and 'W' can not be used.

  • Problem when creating Database with Database, OS and hardware Configuraiton

    Problem when creating Database:
    There are two problems, which I faced during creation of database. When creating database with Oracle Database Assistant. One when creating pre tuned database from CD. And second when creating customized database giving options your self.
    Problem # 1:
    When creating pre tuned database from CD. The process of creating Database is 90 % complete and is at step # 3 Initializing Database. It gives error ORA-03113: end-of-file on communication channel.
    I searched following oracle help for this problem.
    ORA-03113: end-of-file on communication channel
    Cause: An unexpected end-of-file was processed on the communication channel. The problem could not be handled by the Net8, two-task software. This message could occur if the shadow two-task process associated with a Net8 connect has terminated abnormally, or if there is a physical failure of the interprocess communication vehicle, that is, the network or server machine went down.
    Action: If this message occurs during a connection attempt, check the setup files for the appropriate Net8 driver and confirm Net8 software is correctly installed on the server. If the message occurs after a connection is well established, and the error is not due to a physical failure, check if a trace file was generated on the server at failure time. Existence of a trace file may suggest an Oracle internal error that requires the assistance of customer support.
    Conclusion:
    What I conceive from this problem and the help available is that, I have to install NET8 again. But I am not sure about the solution, please tell me whether I am rite or not.
    Problem # 2:
    When creating database with custom option. The process of creating Database is 2 % complete and is at step # 2 Creating Database Files. It gives error ORA-12571: TNS:packet writer failure.
    I searched following oracle help for this problem.
    ORA-12571: TNS:packet writer failure
    Cause: An error occurred during a data send.
    Action: Not normally visible to the user. For further details, turn on tracing and re-execute the operation. If error persists, contact Worldwide Customer Support.
    Conclusion:
    What I conceive from this problem and the help available is that, I have to install NET8 again. But I am not sure about the solution, please tell me whether I am rite or not.

  • Website structure causing problems when creating livecopy based on a blueprint

    Hi,
    Our website structure goes like this:
    company/
         products/
         services/
         contact us/
         etc...
    Our site is single language and hence the structure. Now we have a problem when creating a livecopy (for mobile site) based on a blueprint.
    It seems that for the livecopy (based on a blueprint) to work, the site structure needs to be like this:
    company/
         en/
              products/
              etc...
    It's too late for us to include another layer. What's the best way to create a livecopy based on a blueprint? Or should we just go with livecopy without the blueprint? But then are we missing out on the sync benefit from the blueprint?
    Thanks!!

    Hi Chaack,
    Thanks for this idea. I have tried this before but couldn't get the livecopy to sync.
    I tried to do it through the blueprint by right click and select 'rollout'. But nothing happens. The 'blueprint' tab on the page properties on the livecopy site is grayed out. I think the blueprint I created is not associated with the livecopy and that's why the rollout does not work. If the livecopy was created through 'Create site' then the blueprint is available to choose on step1. But not when you 'create live copy'. Is there anyway to link the blueprint to the livecopy if the livecopy was created through 'create live copy'?
    Thanks!!!

    Hi,
    I would like to suggest you some SAP notes that contain useful information aobut customer-vender intergration of ERP2005.
    956054  BP_CVI Customer-vendor integration as of ERP2005 (ECC600)
    This notes describes the changes (new development) of CVI AND the necessary customizing settings.
    In short, CVI is now bidirectional.
    1. BP -> Customer/Vendor: it depends on the roletype configuration, if a customer/vender is created.
    2. Customer/Vendor -> BP: it depends on the account group if a BP is created.
    Data is changed then synchronoously.

  • Problems when creating a  transfer order for moving storage units

    Hi,
    When creating a TO for moving storage units with FM FU L_TO_CREATE_MOVE_SU i got problems when the storage unit consist of 2 items. The message 'Warehouse number does not exist (new selection required)'
    is displayed. When i use the FM again after this message then the TO is created correctly.
    When i debug the FM for 2 items is see that LEIN-LGNUM is empy en when performing:
    PERFORM T300_LESEN(SAPML03T) USING LEIN-LGNUM. and the message E080 is raised.
    The perform before this is determining the lein-lgnum (PERFORM LENUM_EINL_CHECK(SAPML03T) USING I_LENUM) but this value isnt passed to the calling program the first time (memory or something????)
    Does anyone have a solution for this problem?
    Thx in advance.
    Kind regards,
    John Nijburg

    Hello,
    I had the same problem today and I've fixed it by calling the FM in a different task (asychronous) .. this way the fugr/internal variables will be loaded again and you won't get this stupid error anymore. 
    CALL FUNCTION 'L_TO_CREATE_MOVE_SU' STARTING NEW TASK lv_task
    In case you need it syncronous use PERFORMING clause together with WAIT UNITL
    Hope this helps!

  • Problem when creating a Form with Launch Task Form Wizard

    Hi all,
    I'm using jdeveloper 11.1.1.6 over Windows 7 64bits for my BPM project.
    I'm a new with BPM and i have a problem when trying to create a task's Form with the "Launch Task Form Wizard". I'm trying to create my Form based on a custom template, i already have imported the template as a library, now after i have selected the template i follow the wizard and i reach the wizard's rowX-columnX where i should choose the field i want in my form, but the problem is that i don't see any fields in that part of the wizard, the window is empty :(
    I have created a business object based on a XSD, then i created a process data object based on the previous created business object and finally i used this data object as a parameter to the human task.
    What could be my problem ?? :( :(
    Regards
    Carlos

    I have also faced this issue few times. There could be a namespace issue / schema issue. Please check if you are able to see task:task in the schema section anywhere in the .task file you created. If that is not shown, the fields will not appear while creating human task form.
    Thanks

  • Numeric character problems when creating spatial index

    Hi,
    We have run into a problem when trying to create spatial indexes. The problem seems to be that an mdsys-procedure tries to use a number with a comma as decimal symbol in an update statement
    Error message:

    ORA-06512: at line 1
    Our problem seems to be identical to the one discussed in this thread: create RTREE falied on 9.2.0.4
    Regional settings, language versions etc:
    Client:
    OS: Windows 2000
    Regional options (OS): Swedish, Sweden
    Sqlplus (console and windows versions): v 9.2.0.1.0
    Registry: NLS_LANG =SWEDISH_SWEDEN.WE8MSWIN1252
    Server:
    OS: Windows Server 2003
    Regional options (OS): Swedish, Sweden
    Oracle: v 9.2.0.3.0
    Registry: NLS_LANG =SWEDISH_SWEDEN.WE8MSWIN1252
    We have also tried building the indexes after overriding these settings by setting the environment variables NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1 on both the client- and the server computer. This gives exactly the same error. We have tried setting NLS_NUMERIC_CHARACTERS to '.,' instead of ',.', but this does not help either.
    We haven't tried changing the NLS_LANG registry entry on the server, because this is a production server at a customer's site that hosts several other databases, so we would prefer not to have to restart it if we can avoid it. However, as we understand it, the environment variable NLS_LANG should override the registry setting anyway, right?
    We first experienced the problem when trying to build indexes on imported data. To verify that the problem was not with the data, we wrote a simple test script that:
    1)Creates a table
    2)Creates metadata
    3)Inserts a simple geometry
    4)Tries to create an index
    The error message above is from running this script. We have verified that the script
    works ok on another database server.
    Below are the values of some of the language parameters right before running the script
    (we have tried many other settings with the same result).
    parameter...........................db................................instance...............session
    NLS_CHARACTERSET.......WE8MSWIN1252..................................................
    NLS_LANGUAGE...............AMERICAN...................AMERICAN...........AMERICAN
    NLS_NCHAR_CH...............AL16UTF16 ..........................................................
    NLS_NCHAR_CONV... ......FALSE..........................FALSE..................FALSE..
    NLS_NUMERIC_CH...---------.,---------------------------------------------------------------.,
    NLS_TERRITORY..............AMERICA......................AMERICA..............AMERICA
    The guy who started the thread referenced above solved the problem, but we haven't been able to get it working by changing registry entries and session parameters.
    The question is: Which setting will make the number in 'set sdo_rtree_quality = 1,00000000...' be generated with a . instead of a , as decimal symbol?

    Ok, so here is my plan to solve this:
    1) Change the default user locale (the language under "standards and formats") to English for the account under which the Oracle server runs.
    2) Reboot (or is there an easier way to make Oracle reload the settings?)
    This should make the index creation work. It may break something else however, so to avoid this I can set the user locale back to Swedish afterwards .
    You can subsequently change the setting and update the sdo_rtree_quality in
    the metadata and it should work fine. Do you mean I have to update the sdo_rtree_quality in some way to make it work after I have changed the default user locale back to Swedish? How do I do this?
    Thanks a million both of you!
