Unable to call New Function Module when called thru Internet Service in ESS

Hi all,
I am using 4.6C.
What i want to do: We are attaching a new HTML Template to an iview in which we have a direct call to a newly created Function Module.(Direct call mean to say we are calling the FM thru Flow Editor of HTML template).
What error i am getting : After publishing all edited/created objects when we test it in portal page. It says :
ITS System Information
Flow Execution Failed
Your request could not be processed by the module provider.
The module provide returned following error message: Error retreiving parameters from context
You may check the trace files for more information.
Please guide to solution at your earliest.

Calling New Function Module from JAVA ISA b2b

I need to call a new function module which accepts some parameters as input and
returns some result parameters back as output.
These returned value needs to be displayed on the JSP pages of ISA B2B applications.
Can someone please guide me and provide code snippet on how to do this?
Thanks in advance.
Points will be awarded for all relevant and helpful answers.

Stride,
I did this on CRM ISA 4.0... I used the dev and extension guide as a basis - I think the ISA 5.0 guide has the examples and tutorials in a separate document that can also be downloaded from service.sap.com.
Heres some info on how to do it although I can't guarantee this is the full solution or that it will work the same for ISA 5.0, and I will probably forget a lot of stuff as its been a few years since I did it! I also cant guarantee it is the correct way to do it but it worked! Basically, we built a link into the order overview page to display urls to order tracking websites using an RFC on the backend CRM system. Hope it helps anyway.
1. Create RFC enabled function module in backend.
2. Edit file backendobject-config.xml in folder project_root\b2b_z\WEB-INF\xcm\customer\modification:-
[code] <backendobject
     xmlns:isa="com.sapmarkets.isa.core.config"

3. Edit file bom-config.xml in folder project_root\b2b_z\WEB-INF\xcm\customer\modification :-
[code] <BusinessObjectManagers
     xmlns:isa="com.sapmarkets.isa.core.config"
     xmlns:xi="http://www.w3.org/2001/XInclude"

          className="com.ao.isa.businessobject.Z_AOBusinessObjectManager"
          />
</BusinessObjectManagers>
[/code]
File com.ao.isa.businessobject.Z_AOBusinessObjectManager.java looks like this:-
[code] package com.ao.isa.businessobject;
// Internet Sales imports

     private Z_AOFunc mCustomBasket;
constructor
     public Z_AOBusinessObjectManager() {
Method is called by the framework before the session is invalidated.
The implemenation of this method should free any allocated resources
     public void release() {
Returns custom business object
     public Z_AOFunc getCustomBasket() {
          if (mCustomBasket == null) {
               mCustomBasket = new Z_AOFunc();
               assignBackendObjectManager(mCustomBasket);
          return mCustomBasket;
[/code]
And uses file com.ao.isa.businessobject.Z_AOFunc.java which looks like this:-
[code]
package com.ao.isa.businessobject;
// Internet Sales imports
import com.sapmarkets.isa.core.businessobject.BOBase;
import com.sapmarkets.isa.core.businessobject.BackendAware;
import com.sapmarkets.isa.core.eai.BackendObjectManager;

     // initialize logging
     private static IsaLocation log =
          IsaLocation.getInstance(Z_AOFunc.class.getName());
     private BackendObjectManager bem;
     private Z_AOFuncBackend backendAOBasket;
Returns a reference to the backend object. The backend object
is instantiated by the framework.
@return a reference to the backend object

          if (backendAOBasket == null)
               //create new backend object
               try
                    backendAOBasket =

          return backendAOBasket;
This method is needed when a business object has a corresponding
backend object.
     public void setBackendObjectManager(BackendObjectManager bem)
          this.bem = bem;
Returns a vector of url links for tracking
@return vector of urls
     public Vector getOrderDeliveryTrackingData(String orderNo)
          // the call is delegated to the CRM aware backend object
          return getCustomBasketBackend().getOrderDeliveryTrackingData(orderNo);
[/code]
4. Edit file config.xml in folder project_root\b2b_z\WEB-INF to add custom actions (the section below is just the custom stuff added at the end of the file the Z_orderTracking is the relevant one) :-
[code] 
     <action path="/b2b/Z_orderTracking" type="com.ao.isa.order.actions.Z_OrderTrackingAction">
          <forward name="success" path="/b2b/order/Z_orderTracking.jsp"/>
     </action>
     <action path="/catalog/Z_displaySVGPage" type="com.ao.isa.catalog.actions.Z_SVGPageAction">
          <forward name="success" path="/catalog/Z_SVG_fs.jsp"/>
     </action> [/code]
Which points at Java file com.ao.isa.order.actions.Z_OrderTrackingAction.java which looks like this :-
[code] package com.ao.isa.order.actions;
// internet sales imports
import com.sapmarkets.isa.core.BaseAction;
import com.sapmarkets.isa.core.UserSessionData;
// struts imports
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
// servlet imports
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;
// Internet Sales imports
import com.ao.isa.businessobject.Z_AOBusinessObjectManager;
import java.util.Vector;
This action acts as a template for customer extensions
public class Z_OrderTrackingAction extends BaseAction
This method is called by the ISA Framework when the
action is executed
     public ActionForward doPerform(
          ActionMapping mapping,
          ActionForm form,
          HttpServletRequest request,
          HttpServletResponse response)
          throws ServletException
          // get user session data object
          UserSessionData userSessionData =
               UserSessionData.getUserSessionData(request.getSession());
          // gettting custom BOM
          Z_AOBusinessObjectManager myBOM =
               (Z_AOBusinessObjectManager) userSessionData.getBOM(
                    Z_AOBusinessObjectManager.CUSTOM_BOM);
          // get the order number being processed
          String orderDocNumber = request.getParameter("orderNo");
          // pass the order number back to the page
          request.setAttribute("orderNo", orderDocNumber);
          if (orderDocNumber != null)
               // Get a vector of delivery tracking objects from lower layers (Business Object layer =>
               // Business Logic Service Layer)
               Vector trackingTable =
                    myBOM.getCustomBasket().getOrderDeliveryTrackingData(
                         orderDocNumber);
               String error = "";
               if (trackingTable != null)
                    if (trackingTable.size() == 0)
                         error = "true";
                    else
                         error = "false";
               else
                    error = "true";
               request.setAttribute("errorMessage", error);
               request.setAttribute("trackingTable", trackingTable);
          return mapping.findForward("success");
[/code]
5. I added the call to the function module for page orderstatusdetail.jsp in folder project_root\b2b_z\b2b\order to display a custom page Z_orderTracking.jsp in the same folder. To do this I added a link into the HTML to call a JavaScript function that passed the current order number to the /b2b/Z_orderTracking.do actionhandler mapped in the config.xml file.
So, in summary! Create an RFC; define business managers for it in the XML files; create a new Strut action and supporting Java class; create all the Java class for the managers.
I hope this makes some sense!

Function module when used should not display ALV

Hi ,
All ABAP Gurus
I want to use a function module WS_DELIVERY_MONITOR which should give the VBELN on the basis of CHARG in internal table so that on the basis of VBELN I can fulfil further requirement and display the final output in ALV.
But this function module when executed display an ALV.
My requirement is that it should retrieve all the VBELN on the basis of CHARG (which is in the internal table and is passed to the function module) in an internal table and do not display the ALV so that when all the VBELN come in internal table then I can perform further calculation.
Please guide me in this matter.
Thanks & Regards
Bharti Jain

Hi Bharti,
Please try calling FM 'WS_LM_DATA_SELECTION' instead. This FM is callled inside main FM 'WS_DELIVERY_MONITOR' and is used to fetch data. You will only need to fill extra import parameter for using this FM ( if_flag_inbound) and two changing tables (lt_postab) and ( lt_postab_kodat), which will have results. 'if_flag_inbound' field will be having value X for all inbound cases.
I have used the same FM to get open deliveries:
CALL FUNCTION 'WS_LM_DATA_SELECTION'
    EXPORTING
      if_proctype                 = c_proc_type_f
    TABLES
      it_matnr                    = i_deliv_matnr
      it_lgort                    = i_deliv_lgort
      it_lfart                    = i_deliv_type
      it_kostk                    = i_deliv_kostk
      it_wbstk                    = i_deliv_wbstk
      ct_postab                   = i_deliv_nos
    CT_POSTAB_KODAT             =
    EXCEPTIONS
      no_data_found               = 1
      wrong_proc_type             = 2
      OTHERS                      = 3 .
IF sy-subrc = 0.
**-Calculate open delivery quantity
    LOOP AT i_deliv_nos INTO wa_deliv_nos
                             WHERE NOT posnr IS INITIAL.
      pc_open_deliv_qty = pc_open_deliv_qty + wa_deliv_nos-lfimg.
    ENDLOOP.
ENDIF.

How to do ALV Popup in a new Function module

Hi experts,
This is the Client Requirement.
" Flow Diagram/Pseudo Code:
Attach a data flow diagram. Write brief pseudo code in plain English. Be sure to include all access data plans.
-     FM interface:
-     Import: company code/ vendor#.
-     Export: default_line, type y4ap_t11
-     Exception: NO_DATA or CANCELED
In the FM code, past current z_venddefault code, except for write statements. After internal table is generated, show it in ALV popup. On ALV, add a OK/Cancel button. On OK, ensure that one line is selected (otherwise throw warning), and then fill export structure with that lines G/L account, cost Center, and internal order# fields. Then close the ALV and end FM. For Cancel, just close the ALV end the FM.
For an example of how to build such popup ALVs, take a look at FM Y4AP_SELECT_APPROVER.
Unit Test Plan:
Just use co.code 3000/vend# 1000 to test this FM."

Need help on mapping of obsolete and new function module

Hi Expert,
We are working on a upgradation tool in which i have to repace the obsolete function module "HELP_VALUES_GET_WITH_CHECKTAB
" by "F4IF_FIELD_VALUE_REQUEST
". I am not sure about the functionalities of these function modules as i have never used it. Can anyone please help me by providing some information abt these FMs. Also i need to do the mapping of parameters of old and new function module. So please provide the details of mapping also. Any pointers on this will be highly appreciated.
Thanks & Regards,

Hey Enivass,
you can ckeck the input field "Account Number" whether it is numeric or Alphabet using *"Conversions ->Fixvalues"*
Steps:
1. Extract first character of input using *" Text -> substring"* -- start position 0 , char count 1
2. In Fix Value table you have to give following values:
Dafault value : Alphabet
key----
value
0----
Number
1----
Number
2----
Number
9----
Number
3. Write logic IF "number" than "Arithmatic -> FormatNumber   (0000000000)   -
// for leading zeros
         ELSE
     concat with extra space        -

Impact of Function Modules when used in upgraded versions

Hello Experts,
I wan to know the Impact of Function Modules when used in upgraded versions. How the function module works irrespective of changes done to it in the latest verisons
Thanks in Advance

Hi,
If the function modules is released, it should not have any impact. However if not released, use them with caution as SAP does not support non-released function modules.
Cheers.

Calling a function module when pressing a "F5 key" in the custom field

how to achieve this.
This "F4" key it is performing - i want it in a " F5 key" ....please suggest.

Hi, if you have a report with the standard (generated) screen you only have the possibilities of F1 and F4 (Help and Value request). Otherwise you have to make your own screen and maintain the function keys. Succes

BODI-1112413 : Unable to import a function module from BW

Hi,
I have SAP BusinessObjects Data Services XI 3.2 (12.2.0) and I am creating an interface with SAP BW.
I need to import in BODI several function modules, that were created in BW, and will be called in BODI jobs.
All imports worked except one, which fails and gives the following error message, without much more details:
Unknown error when importing the function <name= XXX >. (BODI-1112413)
This function module was tested in BW and seems to be working properly.
I cannot find more details related to this error return code. So I am a bit lost where to investigate.
Any help would be much appreciated.
Thanks.

Hi,
you can use translate, the ABAP documentation has an example:
DATA text TYPE string.
text = `Careful with that Axe, Eugene`.
TRANSLATE text TO UPPER CASE.
After the conversion, the variable text contains "CAREFUL WITH THAT AXE, EUGENE".
Best regards,

Noob help with creating a new function module

Hi everyone,
I'm just learning SAP and trying to integrate a WMS system towards it and I'm losing hair over it hehehe
The scenario is that I want to extract Purchase Order Rows details and that's not a hard thing to do since there are multiple BAPIs that can be invoked, for example BAPI_PO_GETDETAIL.
I'm using .NET Connector 3 to talk to SAP.
The problem however is that I want to see how many articles that have already been delivered into the warehouse using BAPI_GOODSMVT_CREATE. There is no information returned when using BAPI_PO_GETDETAIL that specifies that a Purchase Order Row has a quantity of 30 and that 20 has already been delivered.
That information can be retrieved by using BAPI_GOODSMVT_GETITEMS.
The problem with using BAPI_GOODSMVT_GETITEMS is that it returns all of the rows and I am only interrested in retrieveing the rows with quantity for a specific purchase order.
So i decided to create my own BAPI or Function Module (or whatever it's called) that would take a PO_NUMBER and PO_ITEM and return the quantity of already delivered items. For example if one of the PO Rows (10) has 100 items and there has been 2 partial deliveries of 20 and 30. The function should return the value of 50 because it's the sum of 20 and 30.
My code looks like this:
FUNCTION ZBAPI_GOODSMVT_GETITEMS.
""Local Interface:
*" IMPORTING
*"     VALUE(PO_NUMBER) TYPE BSTNR
*"     VALUE(PO_ITEM) TYPE EBELP
*" EXPORTING
*"     REFERENCE(ENTRY_QNT) TYPE ERFMG
SELECT SUM( MENGE ) INTO ENTRY_QNT FROM MSEG
WHERE
EBELN = PO_NUMBER AND
EBELP = PO_ITEM.
ENDFUNCTION.
The problem is that when i try to Activate it it says:
REPORT/PROGRAM statement missing, or program type is INCLUDE.
What am i missing? Is there an easier way to extract already delivered quantities when extracting PO information?

Debugging customized function module when Idoc is triggered via ALE

Hi,
Whenever we save the billing document, an outbound idoc is triggered via ALE. The logic for the data to be included in the idoc is written in a customized function module.
However we are making some changes and would like to include some more data in the idoc. But we find that when we put a breakpoint in the function module, on saving the billing document, the flow does not stop at the break point. We are 100% sure that the code in the function module gets executed based on the data in the idoc.
How do we get into debug mode and break the flow in the function module so that we can debug in the function module?
Any help would be greatly appreciated.
Thanks in advance,
Mick

Unable to call a web service from BPEL Project

I am running my BPEL PM on Windows XP SP3. The platform is weblogic 9.2, SOA 10.1.3.1.
I created a simple BPEL project to call a web service and when I run the project from BPELConsole I getting the following error:
exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Bad response: 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )
I am able to call this web service from soapUI client.
Any help or hint is appreciated.

I have had this issue before when calling a .NET service, it was firewall related. I didn't actually make the fix so I can't tell you exactly how it was fixed on the server. I hope this info makes sense as this this the info I got from the IT boys
I’ve install this tool on your computer:
http://www.microsoft.com/downloads/details.aspx?FamilyID=05C2C932-B15A-4990-B525-66380743DA89&displaylang=en
which does that:
Firewall Client for ISA Server can be optionally installed on client computers protected by Microsoft ISA Server. Firewall Client for ISA Server provides enhanced security, application support, and access control for client computers. It provides authentication for Winsock applications that use TCP and UDP, supports complex secondary protocols, and supplies user and application information to the ISA Server logs.
When a client computer running Firewall Client for ISA Server makes a request, the destination is evaluated by the Firewall Client software, and external requests are directed to the ISA Server computer for handling. No specific routing infrastructure is required. Firewall Client sends user information transparently with each request, enabling you to create a firewall policy on the ISA Server computer with rules that use the authentication credentials presented by the client. ISA Server allows you to configure automatic discovery for Firewall client computers, using a WPAD entry in DNS or DHCP to obtain correct Web proxy settings for clients, depending on their location.
and I’ve added a exception in IE to the tools-lan settings-advanced-exceptions to be creditworks.* Did this by modifying the GPO that applies to your account, so all the users in National Office should have that exception.
hope you can use this.
