Payload is not available in Proxy provider class

Hi PI Gurus,
I have developed interface Legacy -> PI - > ECC
The payload flown from PI to ECC successfully and i am able too see the payload in Monitor. But the payload is not getting read and not available in INPUT table of Proxy provider class. The no of record is available in proxy provider class.
I am not facing this issue for other interface which was created with similar data flow.
Thanks and regards,
Mohanraj V.

The payload flown from PI to ECC successfully and i am able too see the payload in Monitor.
Do you see successful message in ECC MONI?
But the payload is not getting read and not available in INPUT table of Proxy provider class. The no of record is available in proxy provider class.
Make sure the proxy is active or was re-generated if there were any changes in the data type in XI. At the other hand check the inbound proxy code once again.

  • Error When Trying to POST: Method not implemented in data provider class

    Hi Experts,
    I have created an Odata Service using Netweaver Gateway Service builder. I am using Advanced Rest Client to test the service. I can successfully GET my data, but I run into issues when I try and POST new data.
    When trying to POST, I used the GET method to get the x-csrf-token, and added it to my header. I also updated the body XML with the data that I would like to POST. However, after sending the POST request, I am getting a "500 Internal Service Error" with the xml message "Method '<OdataServiceName>'_CREATE_ENTITY" not implemented in data provider class".
    Any help on this would be greatly appreciated. Thanks!

    Hi Kelly,
    Can you share screenshots of the error? Maybe something wrong with payload :can you share the same also? Did you try to debug it by putting a breakpoint in the CREATE_ENTITY method in the backend? Any luck?

  • Some classes are not available

    Hi
    I am using JDeveloper 10.1.3
    I have a question. Why some packages are not available for plain JAVA programs.
    For example oracle.webservices.provider.. or
    javax.servlet.httprequest....
    And if you create for example a web service proxy these packages are available for imports.
    Thanks
    Drini

    It all depends on the list of libraries/jars you specify under project properties->libraries.
    When you create a Servlet through the JDeveloper wizard for example, JDeveloper automatically adds the needed jars to your project.

  • Exception "algorithm ARC4 is not available from Provider Cryptix "

    hi all
    i am developing the application in which i am using two encryption/decryption algorithms one is "RC4" and second is "AES(256 bit key)".
    1.first i am taking the credit card number from database which is in
    the encrypted format using 'RC4".
    2.After taking the Credit card number from database i am decrypting them using RC4.

    my program is able to decrypt the only first credit card numbers using RC4 and then encrypt it using AES(as shown in bold above) but it is not able decrypt the rest of the credit card number from the database using "RC4" and it is throwing above exception regarding the "RC4" algorithm .
    can anybody tell me what is reason behind this exception? my guess is the we cann't use the two providers simultaneously.

    Hi Nith,
    Previously I have changed the document dispostal time out to 1 year but the error still occurs.
    Now I change the document inline size from 64 KB to 27 MB (estimated max document size) and see how the LCES behaves.
    I suspect if document size is larger than document inline size then LCES will write to some temp file. After that, user does not process the task for a long time, e.g. 3 days. And during the 3 days, the unix system/ websphere auto clear the temp file. After 3 days when user accesses the task again, LCES will complain "document is not in sending server side any more" ....
    I refer to : http://blogs.adobe.com/livecycle/2008/10/livecycle_tuning_knob_default.html
    For the Document sweep interval, I think, it relates Watch Folder, not this error so I don't change it.
    Regards,
    Anh

  • Service not working after altering Model provider class

    Dear all,
    I have created a OData service and consumed it successfully. I was able to post data to it. Now after altering the "model class" i.e., adding one property and changing ABAP Dictionary type. After doing these changes but i couldn;t consume the service and get "500 Internal server".
    Did anyone experience this problem? Please note i didnt use Service builder(SEGW) to create a project instead i did all manually using Model and Data provider classes.
    Please suggest. Your help is appreciated.
    Points will be awarded to helpful answers.
    Regards
    Prabaharan

    Hello Prabaharan,
    This is a generic error at client side and there can be multiple reasons for it. This error is from the hub system and only way to check this error is to look into error log and application log in hub system.
    Common Problems: property type errors (date, decimal/precision etc.)
    But looking at the problem you are facing like Ron suggested you might get 500 internal server error because properties like data and time need to be defined nullable and you might have missed that.
    Kindly check and mark fields as nullable if properties you are sending in the payload are null values.
    lo_property->set_nullable( ).
    Cache clean up is required only when you have done some changes to your model.
    See the metadata and confirm if the new property added by you is present. if you are not able to see then do the following.
        Try Clearing the cache using /n/iwbep/cache_cleanup and /n/iwfnd/cache_cleanup t-code.
        Also clear server cache using /nsmicm t-code as shown below.
    Regards,
    Ashwin

  • Auth Objects for Class - PP not available on PFCG

    Hi,
    We have upgraded the syetem from GTS3.0 to GTS8.0. The scenario is -- although a TCode for the PP Class ( e.g CC11 or CC12 ) has been maintained in SU24, the corresponding check maintained authorization objects are not available within PFCG. I even tried to create a dummy role and add only trx: CC11, only the S_TCode got updated.....whereas the check maintained objects like C_AENR_BGR, C_AENR_ERW & C_AENR_RV1 were not available.
    But if I add trx from any other class like SU53 or WE21 within the same dummy role, the corresponding check maintained authorization objects get updated within the role.
    Any help regarding this to fix the issue is highly appreciated.
    Regards,

    Looks like someone toasted your proposals from a lower release or even in a DB table copy.
    I would look into this and track the cause down, to stop it.
    Take a look in the menus of SU24 for change documents. (USOB*CD tables).

  • Provider for OLD DB Not available

    Hi Experts,
        I have installed IDM 7.1 with Oracle 10.2 as DB. I have installed the identity center, runtime components and all necessary libraries and drivers. Now, While creating a new identity center configuration in Management console, for the first connection string I selected the "Oracle Provider for OLE DB" in datalink properties wizard, as mentioned in the installation document. But, i get the following error message on clicking 'Next'.
      " Provider is no longer available. Ensure that the provider is installed properly ".
    Please help me if you know where to check the provider?
    Note: The installation is on 64 bit windows server 2003 OS.
    Regards,
    Vijay.K

    Hi Sahad,
        I guess you have misunderstood with the problem and solution.
    Problem:
    In a 64-bit Windows server machine, Oracle (64-bit) server and Identity center(management console and Runtime components) are installed, but during creation of connection string, "Oracle provider is not available" message is received
    Solution:
    Install a 32-bit oracle client in that machine because identity center requires only a 32-bit oracle client with OLEDB provider (irrespective of whether the machine is 32-bit or 64-bit).
    If your problem is something different, create a new thread. If not, you don't have to look for 64-bit oracle client. 32-bit oracle client can be downloaded from http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winsoft.html
    Yes, you will require some logon, for which simple self-registration is sufficient.

  • Counting class of period work schedule not available on 01.01.2012

    HI SAP GURUS,
    while  creating attendance through info type 2002 for an employee its giving error message i.e " counting class of period work schedule 03/KGPG not available on 01.01.2012. Please suggest.

    Check out this link in the IMG:
    IMG > Time Management > Time Data Recording and Administration > Attendances/Actual Working Times > Attendance Counting > Define Counting Classes for the Period Work Schedule
    Under the PSG Grouping 03, and PWS KGPG, maintain the value = 1 (or other class as required).
    If you do not find the entry, you need to create a new record.
    Also, under the Counting rule (that you assign to your attendance) make sure that the appropriate Counting class for PWS is checked mark otherwise your attendance will not be counted properly. You can create the couting rule with this IMG step:
    IMG > Time Management > Time Data Recording and Administration > Attendances/Actual Working Times > Attendance Counting > Rules for Attendance Counting (New) > Define Counting Rules
