hi,
call function 'ZV_SALES_ORDER_CANCEL_TSPPRA'
    exporting
      salesdocument = l_order
      customer      = l_kunnr
    importing
      return        = return
the return contains the error message.
how to display this error message in our program

Hi Sudarshan,
What is the type of return. Is it a BAPIRET.
Then just check for the MSGTYP and if it is E then show the error.

  • Getting error in the function module

    Hi everybody.
    I have created one function module in se37 and i am calling that function module in the se38 report, when i am executing the report it is throwing me an error.
    here in my report i am having the select option fields ex matnr, in the function module importing i have given the parameter matnr over there and when i am running the report it is through an error that 
    "The function module interface allows you to specify only 
    fields of a particular type under "MATNR".               
    The field "S_MATNR" specified here is a different        
    field type                                                "
    IF i am giving the parameter instead of select-options in the report and executing, then the function module is getting triggered and receiving the data what ever the code is available in the source code.
    can anyone help me out in this issue so that i can get the data while using the select-option instead of parameter.
    Thanks in advance

    Hi,
    Actually, I wouldn't recommend the use of that tables parameter...
    From sap help:
    Table parameters are obsolete CHANGING parameters that are typed as standard tables with a header line. If an internal table without a header line or a table body is passed as an actual parameter to a formal parameter of this type, an empty local header line is generated in the function module. If an internal table with a header line is used as an actual parameter, both the table body and the header line are passed to the function module. Pass by value is not possible in formal parameters defined using TABLES. Formal parameters defined with TABLES can be replaced by formal parameters defined with CHANGING. A local work area can be created for the internal table in the function module by using the addition LIKE LINE OF itab of the DATA statement.
    Exceptions
    So i definitely would go with either importing or changing parameter...
    Cheers,
    m.

  • Error during generation of the function module..need help urgently

    Hello everyone,
                            m trying to generate data source in BWDevelopment.

    'An error occurred in step 1 during generation of the function module'

    Where could be the problem?
    Thanks & Regards,

    Hello everybody,
                             my problem is solved.For the UDConnect, whatever DATA SOURCES you create gets registered in a FUNCTION MODULE which has a capacity of only 99 enties, so to increase it implement the SAP NOTE 876340 - UDC Error available on SERVICE MARKET PLACE.
    This problem occurs with BW version 3.5 level 17 or below.

    hii vinu,
    hi there....
    make sure that the Processing type in Attributes tab is 'Normal function module'. Also chk the general data, it must be having some name in the Program Name and include name column.try checking the program names in se38, if the program is of type include or not. you can also chk by writting  a program call the function module and test it
    I hope this will solve the query. in my case, SAPLZ123 is the program name and LZ123U28 is the include name.
    or
    Its common prob with Function module.
    Goto SE80->Give Function group name->Right click on it->Activate.

    Hi,
    Check if any proxy is maitained in the client by going into transaction
    SICF-> Goto-> HTTP Client Proxy -> HTTP LOG TAB.
    If there is anything maintained under Host name and port, if yes you need to specify the IP address while calling FM HTTP_POST
    under PROXY as
    192.168.0.1:8080  where first part is IP address & 2nd part(8080) is port.
    Also test connection for SAPHTTPA under SM59 to see if its properly configured.

  • Identify tables from where the function module extracts data for the ES

    Hi All,
    For the datasource, 0CRM_SALES_ORDER_I in the CRM system, we need to add a new field (in the table level). This datasource's extraction type is 'F1 - function module'. Is the extractor itself is this function module? If it is a sepeate FM, where can we find the function module name used for this datasource?
    We need to identify the tables from where the fields in this datasource fetch data from. Where can we find this information?
    To be specific, in the sales order in tcode crmd_order, if we goto conditions tab and create a new condition, in what table this will get stored?
    Thank you in advance,

  • RFC_ERROR_SYSTEM_FAILURE: The function module "DD_DTEL_GET" cannot be used.

    Hi there,
    I´m trying to launch NWCE 7.1 Webdynpro applications accessing ABAP function with no success.
    The landscape consists of an SAP NWCE 7.1 EHP1 (Trial) and an SAP NW 2004s ABAP (Licensed). NW2004s is configured as Gateway and Message Server for the SLD. I can ping/test JCOs successfully and the SLD seems to work fine. RZ70 and SM59 show no errors in the "R3" side and both systems seem to be well-registered as Technical Systems.
    I have done some simple examples in Developer Studio to ensure that the conection between both stacks is going well, but I have allways the same issue regardless using ARFC/ARFC2, new projects/old existing projects, etc.
    When I test for first time the application, the following exception is thrown:

         wdComponentAPI.getMessageManager().reportSuccess("After catch.");
         // Resynchronise the data in the context with the data in the model
         wdContext.nodeOutput().invalidate();
    The first two exception seem to be related each other, and it is true that FM "DD_DTEL_GET" is not RFC enabled in R3. Should it be RFC enabled?
    As far as I know, one of the JCO conectors is used for retrieving metadata, that is, data related to types, lenghts, etc. The FM "DD_DTEL_GET" is used for that kind of operations and the second exception is related to that aswell (com.sap.mdi.ddtypes.DDDataelement.getDescription).
    I don´t know what else should I test in order to launch an RFC function from WDJ and the trial version is about to expire!
    Does anyone know about any oss note or any other tips related to this issue, please?
    I am going to test the conectivity via Visual Composer and see whether it´s possible :S

    Language resources data in the webdynpro are: Current locale = "es", Default VM locale = "es_ES". The backend default language is "EN". Could this be a problem in order to retrieve descriptions or any other language dependent data?
    Thank you

  • Regarding the function modules

    Hi anybody pls tell me
    what are the scenarios for the creation of function module
    can you give me the some examples
    thanks in advance

    <b>Function Modules</b>
    Function modules are procedures that are defined in function groups (special ABAP programs with type F) and can be called from any ABAP program. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the  Function Builder.
    Function modules allow you to encapsulate and reuse global functions in the R/3 System. They are stored in a central library. The R/3 System contains a wide range of predefined function modules that you can call from any ABAP program. Function modules also play an important role in database updates and in remote communications between R/3 Systems or between an R/3 System and a non-SAP system.
    Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the  Function Builder. The actual ABAP interface definition remains hidden from the programmer. You can define the input parameters of a function module as optional. You can also assign default values to them. Function modules also support exception handling. This allows you to catch certain errors while the function module is running. You can test function modules without having to include them in a program using the  Function Builder.
    The  Function Builder also has a release process for function modules. This ensures that incompatible changes cannot be made to any function modules that have already been released. This applies particularly to the interface. Programs that use a released function module will not cease to work if the function module is changed
