Web Service from RFC function module

Hi all,
I'm searching for a way to create web services from RFC-enabled function modules. I know there is a wizard, but it's not suitable for my problem:
I have around 30 function modules (number raising in near future) I want to enable for web services, most of them share the same structures representing the underlying data model. When one structure is modified (i.e. a new sub-structure is added) I have to recreate all web services, which is quite uncomfortable.
In addition, using the wizard results in one wsdl-file for each web service operation, that leads to an administration overhead using this web services from a java frontend.
So I'm searching for a "bulk creation". I also know the wizard can be used for a function group, but I can't put all my RFC-enabled function module in one function group, that would lead to confusion in the package.
Does anyone know how web services are created programmaticaly? If I had a function module which creates the web services I could write a function module which creates all web services I need.
Thank you in anticipation!
Florian

I'm not sure I understand the 're-create' part...how are you re-creating the web service? if you modify the interface of a function-based web service, then you use the 'modify operations' functionality (context menu - right-click) to regenerate the web service interface; this works for a function group based web service as well and hits all of the methods at once. As for the java overhead on function group services, stating the obvious, maybe you just need to lower the number of functions in your groups. We use .Net-developed applications with multi-function webservices and don't have any overhead issues.

Web Services from ABAP function modules return values- leading zeros

I am using several web services from SAP CRM (5.0) that were created from Function modules ( I am assuming that that they are in ABAP).
I can call the web services fine and they work as expected, but I am seeing a lot of leading zeros in the return values of fields in tables from the Web service.
The ABAP ers are telling me that they cannot see the leading zeros.
So my question is where these are appended to the values in the whole process. When I execute the Function Module in SAP CRM from transaction SE37 I can see the leading zeros. So I think that this is something that has to be handled by the ABAP ers and not in the client consuming the web service.
Are the functions in SAP CRM that can remove leading zeros for fields in a table (that is an export parameter?)
Jawahar

Hello Jawahar
If you run your (RFC-enabled) function modules using the SAP-GUI (i.e. in dialog) then the GUI automatically replaces leading zero when the function module returns any data. However, calling the same function module remotely you will always see these leading zeros.
These so-called conversion exits are defined as attribute of domains in the ABAP dictionary. If the function module used for the WebService is a standard fm then you have little chances to get rid of the leading zero. Perhaps the WebService has some attribute to suppress conversion exits or activate them when retrieving the data.

Error while generating Web Service from a function module.

Hi Experts,
I am trying to create a web service from function module by doing the steps as mentioned in the below document:
http://www.sdn.sap.com/irj/scn/index;jsessionid=(J2EE3417800)ID1146834250DB10778842957931285337End?rid=/library/uuid/80fa3dff-ce76-2a10-3f94-f3df8f2db5a2&overridelayout=true
When i save it as an local object instead of generating the Web Service it gives me the below error:
"Error during activation of Web Service"
Kindly let me know what needs to be done inorder to resolve this issue.
I have a feeling that this error may be with respect to some authorizations, in that case how do we resolve it
Helpful Inputs Awaited.!!!

Test web service for a function module

Hello,
I have created web service for a functiona module. I can see the same service in SE80 in Enterprise Services.
How do I test this service?

Thanks Venu for your input.
Unfortunetly we do not have Java stack on our development system. You said we can test it by SOAP UI tool. Where do I see the WSDL file for the service?
I used WSDL from SE80 --> Service --> WSDL tab, but SOAP UI does not accept this format ?
What are the other ways I can test this web service? I think about SAP PI, importing RFC & creating web service or creating ABAP proxies... Which is the best way to go forward in case you do not have Java stck.

There is no any error message show up. It just the class

Assemble Web Services from database functions and procedures?

Web Service Assembler can assemble Web services from PL/SQL packages.
Can it be used to assemble Web services directly from functions or procedures?
Thanks,
Jim

Hi,
No, it relies on a package and takes each of the publishable functions and procedures as the web serivce methods.
Have you also tried using JDeveloper? It uses WSA under the covers but gives you a great GUI for selecting and working with your code

How to take back the control from RFC function module to calling program

Hi,
In our system landscape, more than 200 child systems are connected to Solution manager(SMP). I have copied a RFC enabled function module into all the child systems and calling that FM from Sol Man in sychronous mode.
Here goes my code in SolMan.
LOOP AT it_dest INTO wa_dest.
CALL FUNCTION 'Z_GET_LOGIN_DETAILS' DESTINATION wa_dest-rfcdest
    EXPORTING
      date_fr               = s_date-low
      date_to               = s_date-high
    TABLES
      tab_data              = it_val
    EXCEPTIONS
      communication_failure = 1
      system_failure        = 2
      OTHERS                = 3.
IF sy-subrc EQ 0.
*     Updates zuserlogon
      MODIFY zt_logon_det FROM TABLE it_val.
      COMMIT WORK.
      WRITE:/'RFC for Destination', wa_dest-rfcdest, 'succesfully updated.'.
ELSE.
      WRITE:/'RFC for Destination', wa_dest-rfcdest, ' failed.'.
ENDIF.
ENDLOOP.
Few child systems are very slow & takes more than 20 minutes(Many of the times system hangs) to return the result. But I should not wait for so long. Even if the child system doesn't return any values in 5 minutes I shoud continue with other system ignoring the current one.
I tried calling the FM in asynchronous mode(STARTING NEW TASK) but no success because only 6 DIA processes possible but as I said I have more than 200 systems connected to SolMan.
Please help me resolving this problem.
Thanks,
Prathap

If there are only few child systems with bad response time, use asynchronous call using a CALL FUNCTION func STARTING NEW TASK task DESTINATION dest PERFORMING subr or CALLING meth ON END OF TASK. Count asynchronous calls still running/waiting (increment a counter when creating a task (not the one used for task id). In the form/method performed at end of a call decrement the counter. When counter is lower than a limit, 4-5 if 6 processes (*), perform an asynchronous call else perform a synchronous call or wait until the counter falls below the limit.

Raymond
(*) Use SPBT_INITIALIZE at start of program to get actual number of free/available processes.

Unable to retrieve parameters from RFC Function Module

Hi All,
I have created a model for the RFC Enabled function module BAPI_BUPA_CENTRAL_GETDETAIL within my webdynpro program. I am passing parameters to the function module BAPI_BUPA_CENTRAL_GETDETAIL and I have validated that this is being passed correctly by displaying the passed value from the node of the input parameters.
Code used to pass input parameters -
IWDMessageManager manager = wdComponentAPI.getMessageManager();
   try
      wdContext.currentBapi_Bupa_Central_Getdetail_InputElement().modelObject().execute();
      size = wdContext.nodeCentraldataperson().size();
      wdComponentAPI.getMessageManager().reportSuccess(Integer.toString(size));
      wdContext.nodeOutput().invalidate();
   catch(WDDynamicRFCExecuteException e)
      manager.reportException(e.getMessage(), false);
I also see that it returns 1 record by using the code below:
IWDMessageManager manager = wdComponentAPI.getMessageManager();
   try
      wdContext.currentBapi_Bupa_Central_Getdetail_InputElement().modelObject().execute();
      size = wdContext.nodeCentraldataperson().size();
      wdComponentAPI.getMessageManager().reportSuccess(Integer.toString(size));
      wdContext.nodeOutput().invalidate();
   catch(WDDynamicRFCExecuteException e)
      manager.reportException(e.getMessage(), false);
But, when I try to retrieve the value returned it does not fetch that value -
   Bapi_Bupa_Central_Getdetail_Output getdata = wdContext.nodeBapi_Bupa_Central_Getdetail_Input().nodeOutput().currentOutputElement().modelObject();
   Bapibus1006_Central_Person[] getres = new Bapibus1006_Central_Person[size];
   for(int i=0; i<size; i++){
        wdComponentAPI.getMessageManager().reportSuccess(Integer.toString(i));
        getres<i> = getdata.getCentraldataperson();
        //String fullname = wdContext.nodeBapi_Bupa_Central_Getdetail_Input().nodeOutput().nodeCentraldataperson().getElementAt(i).getAttributeValue("Fullname").toString();
        String fullname = getres<i>.getFullname();
       fullname += Integer.toString(i);
        wdContext.currentContextElement().setFullname(fullname);
        wdComponentAPI.getMessageManager().reportSuccess("fullname:" + fullname);
It always returns 0 or null. Can someone please help me with this issue. The BAPI returns values in structure format and not internal table and hence I dont see the issue there as well.
What can be the problem?
Thanks for all your help in advance.
Best regards,
Divya

Nikhil / Srihari,
I changed my code and it now looks like - I am trying get the return value into the context fullname but i still cant get the value although the size of nodeCentraldataperson() is thrown as 1 and the input is being passed correctly as i have validated this in this line of code [wdContext.nodeBapi_Bupa_Central_Getdetail_Input().currentBapi_Bupa_Central_Getdetail_InputElement().getBusinesspartner();]
IWDMessageManager manager = wdComponentAPI.getMessageManager();
   try
      wdContext.currentBapi_Bupa_Central_Getdetail_InputElement().modelObject().execute();
      size = wdContext.nodeCentraldataperson().size();
      wdComponentAPI.getMessageManager().reportSuccess(Integer.toString(size));
      wdContext.nodeCentraldataperson().invalidate();
   catch(WDDynamicRFCExecuteException e)
      manager.reportException(e.getMessage(), false);
     for(int i=0; i <size; i++){
          String name = "FullName: ";
          wdContext.nodeBapi_Bupa_Central_Getdetail_Input().nodeOutput().nodeCentraldataperson().setLeadSelection(i);
          name += wdContext.nodeBapi_Bupa_Central_Getdetail_Input().currentBapi_Bupa_Central_Getdetail_InputElement().getBusinesspartner();
          name += wdContext.nodeBapi_Bupa_Central_Getdetail_Input().nodeOutput().nodeCentraldataperson().currentCentraldatapersonElement().getFullname();
          wdContext.currentContextElement().setFullname(name);
Any idea what could be wrong?
Thanks,
Divya

Is possible to compare a web service like a function module ?

Hello all,
I'm new in ABAP web service ( not java, not PI ). I have to create a web service to send some file
from sap system towards external system and I'm learing some documentation.
To send a file with web service I need to create an interface with Internet Comunication Manager and
when this interface is created,
how can I send my file with web service ? I need to create a FM or other object ?
tks a lot,

Procedure for Mapping two types of Idocs from RFC function Module

Hi
My Scenario is RFC -- XI -- IDOC
Here i have 2 custom Idocs
First IDOC for Creation
second is for Deletion/Changing
Based on the condition from RFC it should trigger either one of the IDOC above.
Please provide me the procedure to do in IR and ID..
Regards,
Yeswanth.

YeswanthRaj:
I found your conflicted statements
The following statement you say you just have one receiver, to receive two IDOCs
But i have only one receiver where the 2 IDOcs needs to be send based on the condition..
The following statements showing that you have more than one receiver,
the condition editor for receiver determination usually used for multiple receivers based on XPATH or Context Object condition
It is mapped based on the condition that is given in Receiver Determination and i has two interface Determinations.
It seems that the first scenario is your situation.
If your answer is yes, and your source interface is just one,and target interface is two (two IDOC), then this should be typical
muti-mapping scenario, and the propose I gave to you should fit
Regards.

Error calling web service from Adobe form

Hi Experts,
While calling web service form my adobe form, i was getting an error as below saying "Error attempting to read from the file" followed by the URL of my web service.
To create the above scenario i followed the following steps:
1. Create a Function module and create a web service from that function module.
2. Through SOAMANAGER, download the WSDL file for the generated web service.
3. Create an Adobe form with an empty Interface and create a new Data Connection on the form using the downloaded WSDL.
4. Generate this adobe form using an ABAP report.
Kindly extend help on this to figure out if I'm missing something!!!

Well questions related to Web Services have been answered here in past, please Search on SCN for links to it.
