Can we call a function module from a structure?

Hi everyone,
I have a requirement to send an idoc. I have to populate a segment with signing authority . I have to create a custom table for that and call the function module. How do i do that ?
Thanks in advance,
Venkat

Hi!
When you have an outbound IDOC, then there is a function module to create the IDOC and fill the segments. Often the function name follows the form MASTERIDOC_CREATE_NNN with NNN = IDOC-name.
Inside this function module should be an user exit to add some own coding.

Christian

    I was told that yu can not call a function module from a smartform - that does not make sense to me because you can do tons of ABAP within a smartform.
    Well - can you?

  • Calling a function module from APO Macro

    Hi,
    Can I call a function module from a macro directly without going through the user exit? If so, how should I pass the parameters to the function module? I don't have to get the results back to macro.
    Regards

    Hi Asokan - you can call a function module directly from a macro providing it is designed to be called from a macro. For example if you are in the Macrobuilder and use the menu path Edit -> Edit User Function then you will get a list of existing function modules that you can call directly by inserting a Operator/function into your macro. If you want to call a function module not listed in the User Function drop down list then you will either need the user exit or create a custom function module as a wrapper and register the wrapper function module in the Edit User Function menu path. Calling a function module will always return a value - but you can choose to ignore that value depending on how you build your macro.

  • Can i call a function module of SAP?

    Hi, i have a question... Can i call a function module of SAP... I need print a document from a device, can i call the function module of SAP in order that me it prints it?
    Thanks,

    Hi Victor,
    you can use the GenericSync Example of the MDK. This calls the Module to verify the user directly. Generic Sync is exactly for that purpose: call a BADI directly and no usage of SyncBO. Be aware, that you - out of the box- sync your app data as well at that moment, because a sync runs both - generic and smartsync. Even worse: even when you have nothing to sync in Generic Sync - so nothing to print - it will call the function module for generic sync as long as it is registered.
    Well,  anyway, this is the way to call a function module separate.
    If it works with you rparticular print module? I have no idea, but if this is a normal function module - well, it should be ok.
    Hope this helps.
    Regards,
    Oliver

  • Can one call a function module in Calculated Key Figure?

    Can one call a function module in Calculated Key Figure? If  yes how, if not, what is the solution if formula does not suffice?
    I want to convert duration which is in seconds to   Duration in Hours and Minutes. There is a function module for doing it. Not sure how to do it in a formula.

    One option you have is a Virtual Key Figure and User Exit to use the Function Module to convert the time from seconds to HH:MM. Here are two documents on this subject to help you create them, based on the technology your comfortable with:

    Hi Rael,
    We were finally able to call a FM module from the Web. The trick as Heike suggested was to create an ABAP class which inherits from CL_RSR_WWW_HELP_WINDOW. Then you should modify the process_cmd method of this new class in order to call the FM. Now use this class to create a help service. In case you need to pass any parameters to the FM, you will need to pass them as additional parameters while calling the help service.
    An example is below.
    CMD=PROCESS_HELP_WINDOW&HELP_SERVICE=ZBOOKMARKING&TEXT=mytext&URL=myurl
    Where mytext and myurl were the parameters i pass to my FM and ZBOOKMARKING is my help service.
    Thanks a Lot to Heike for his help on this !!

  • Can we call a function module in ADHOC query

    Okay as far as I understand your aim is:
    To fill a field in the output list with a value that is based on the current line information and calculated by a function module
    So go to SQ02 and create an additional field in the InfoSet.
    You can refer in the coding to the technical names you can see in the left tree window like P0000-PERNR.
    More information is avaiable in the Help part look for additional field in SQ02.

  • Can we call a Function Module with in a loop

    Hi,
    Can we call a Function Module within a loop . Does it reduces the performance.
    Can you please guide regarding this.
    With Best Regards

    hi Mamatha,
      You can call .. but it is better to avoid calling it within a loop...
    Loop at it_tab.
       call function 'CONVERSION_EXIT_ALPHA_INPUT'
        exporting
          input  = it_tab-vbeln.
        importing
          output = it_tab-vbeln.

  • CNTL_ERROR while calling a function module from Java webdynpro

    I am calling a RFC function module from javawebdynpro app
    which inturn calls a function module performing BDC on CAPP transaction. When I run this from SE37 of the same system or a different system everything works fine. But when called from Java webdynpro app, it raises a CNTL_ERROR exception and creates a short dump.
    Any help on this is highly appreciated

    Good catch, BI Learner. This was exactly it: when assigning the values from SOURCEFIELDS directly to the import/export parameters, you have to make sure that the types are EXACTLY the same, otherwise it will not work (the routine stops with an error when calling the FM, but there is no dump).
    Therefore, to solve my problem, I created the declarations precisely as expected by the FM and assigned the values to these fields:
    DATA:
          SOURCEVAL TYPE  /BIC/OIINVQTY,
          SOURCEUOM TYPE  /BIC/OIUSUOM,
          USITM TYPE  /BIC/OIUSITM,
          TARGETUOM TYPE  /BIC/OIUSUOM,
          CONVERTED_COST TYPE  /BIC/OIINVQTY.
    DATA PRODUCTION_UOM TYPE /BIC/OIUSUOM.

        SELECT SINGLE I~/BIC/USPRDUOM
          FROM /BIC/PUSITM AS I
          INTO PRODUCTION_UOM
          WHERE I~/BIC/USITM = SOURCE_FIELDS-/BIC/USITM AND I~OBJVERS = 'A'.
        IF ( SY-SUBRC = 4 ). " no records found
          "RAISE PARTNO_NOT_FOUND.
          RAISE EXCEPTION TYPE CX_RSROUT_SKIP_RECORD.
        ENDIF.
    " load the parameters
        SOURCEVAL = SOURCE_FIELDS-/BIC/USFRZMFC.
        SOURCEUOM = SOURCE_FIELDS-BASE_UOM.
        USITM = SOURCE_FIELDS-/BIC/USITM.

  • Call ABAP function module from script?

    Hi,
    I have an ABAP function module, which works fine when I call it in a transformation.
    Since I don't need to execute this function for each record but rather for each file I process, I would like to move the call from the DataFlow to a script in the WorkFlow. When I click on the 'functions' button the ABAP FM is available in my SAP Datastore, so I drag and drop it into my script. I also make sure to populate all required variables.
    There are no error messages or warning when I check my job definition.
    When I execute it, I get the following RFC error:
    Function call <xxx  ( abcd ) > failed, due to error <150413>: <RFC CallReceive exception <FUNCTION_NOT_FOUND>.>.
    Is it just not possible to call an RFC enabled function module in SAP from a script or am I doing something wrong here?
    Thanks,
    Jan.

    Could you please let me know how I can call an abap function module from a transformation? (from abap xslt program). I know how we can call methods of a class from the transformations, but no idea how we can call function modules. Any suggestions or a sample code snippet towards this will be very useful for me.
    Thanks,
    Shashi.

    Ya. I can do that. But I don't want to use a class and a method to call that function module. Want to directly call function module from transformation. Is that possible..?

  • Calling a function module from within a transformation routine

    I created a routine within a transformation and experience the following weird behavior now:
    When I call a function module within that routine, the load fails with the following error message:
    Exceptions in Substep: Rules
    When I click on the button next to this text, it point me to my function module call.
    What I do not understand is, that the following two scenarios work fine:
    - Having the same function call (with fake values) in a plain ABAP program works beautilfully
    - If I copy the content of my function module directly into my transformation routine, everything works fine as well
    I am now wondering whether the routine does not "see" the function module I am calling. The module resides in a different package. Is that a problem? Do I have to include something first?
    Here is the code that calls my FM (
    CALL FUNCTION 'Z_CA_CONVERT_US_COST'
         EXPORTING
            PSOURCEVAL                      = SOURCE_FIELDS-/BIC/USFRZMFC
            PSOURCEUOM                      = SOURCE_FIELDS-BASE_UOM
            PUSITM                          = SOURCE_FIELDS-/BIC/USITM
