Integration between Purchase Requisition & external web services

Hi
We have a requirement to Integrate Purchase Requisition Process in MM & external web services(Portal).So we wanted to know what are the third party tools that SAP supports inorder to integrate both the systems.The requirement is like a business user from Logistics team enters a PR on a portal and the data flows to SAP through a connector and creates a PO automtically if it has got sufficient data.
Regards
Prasad

Hi,
If you have the any transaction codes that are required to do the process in the backend MM, use the same tcodes and create the SAP Transaction iViews in the Portal.
You can have three GUI (for look and feel) in the Portal iViews, SAP GUI for Windows that is the default one, SAP GUI for HTML has the Web look and feel, which requires you to configure the ITS and SAP GUI for Java. Depending on your requirement you can use any of the three.
Hope this will help you.

Best practice for integrating oracle atg with external web service

Hi All
What is the best practice for integrating oracle atg with external web service? Is it using integration repository or calling the web service directly from the java class using a WS client?
With Thanks & Regards
Abhishek

Using Integration Repository might cause performance overhead based on the operation you are doing, I have never used Integration Repository for 3rd Party integration therefore I am not able to make any comment on this.
Calling directly as a Java Client is an easy approach and you can use ATG component framework to support that by making the endpoint, security credentials etc as configurable properties.
Cheers

Link between Purchase requisition & service master

Dear Group members
Is their any link between Purchase requisition T code ME51N & service master T code (AC03)
Can i create service order in Purchase requisition
Regards
Shamul heq

You can use the Service master created using T code AC03 while creation of Purchase Requisition.
You cannot create service master using T code ME51n

Integration of Oracle ATG with external web service

Hi All
I am new to Oracle ATG 10.1 and am trying to integrate ATG with an external web service. I checked the documentation library and checked ATGWSFrameGuide but it only helped theoritically. Can anybody share any resource / docs to explain how to integrate ATG with web services.
With Thanks & Regards
Abhishek

There is no rocket science involved here. Just create a component whose properties file can contain the required properties like the wsdl path,etc. Create the stub classes out of the wsdl, jar it and place it in your classpath. Populating the request data into stub and invoking an operation will be similar to the one that we use in normal java while working with web services

Need to invoke a external web service

Hi folks,
I am new to XI. I need to create a BPM process which has to trigger an external web service. Could any one tell me how can i proceed in this?
Steps what i have done so far in this regard is ,
1. consumed a external web service into IR as external definition
2. created message types similar to this external definition message types.
3. Created Inbound interface(for external service) and outbound interface from my system.
4. Created the operation mapping & message mapping between this 2 messages.
So in the integration directory , i didnt start with the process. So kindly help me in this process.

Any clues?
Thanks

WS Binding: exception durign SOAP invocation: java.util.NoSuchElementException
Looks like the error is in the data sent to or expected from the service in your composite. Check that audit logs and composite flow to make sure your soap message when using soapui matches what you are working with in soa suite.

Tell me the link between Purchase Requisition and Sales Order Number

tell me the link between Purchase Requisition(MEREQ_TOPLINE-BANFN_EXT) and Sales Order Number(COBL-KDAUF)

Hi Puja,
If you have created sales order for matrial which has both procurement type,after MRP run you will get
planned order.This planned order you can convert to purchase requisition for external procurement or
subcontracting.
You will find sales order number in details of purchase requisition ( ME52N) in Account assignment tab.
Hope this help you.

Initiating BPM Process Instances from External Web Service Call

I'm attempting to update the HelloWorld example so that I can create an instance of the process from an External Web Services Call rather than via the Workspace. Our current SOA Architecture is configured so that all BPM instances are managed through a .NET SmartClient via the Service Bus and the use of PAPI W/S and so I'm wishing to recreate this capability in the new BPM.
I understand the replacement for PAPI W/S is Human Workflow so I've therefore updated and republished the HelloWorld Example with an Exposed 'TaskService' Service for the Human Task within the BPM Process.
I've then attempted to reference the TaskService through our existing BPM, and have been able to import a number of generic WSDL's as follows:
Task Service
http://vmaquatestapp2:7001/integration/services/TaskService/TaskServicePort?WSDL
Task Metadata Service
http://vmaquatestapp2:7001/integration/services/TaskMetadataService/TaskMetadataServicePort?WSDL
Task Query Service
http://vmaquatestapp2:7001/integration/services/TaskQueryService/TaskQueryService?WSDL
When I examine the available operations for these generic services, there are quite a lot, each of which have a fairly complex schema. I believe I should be using the TaskService: InitiateTask Operation to create an instance of my BPM Process but my questions are:
- Is the above the correct method of interacting with BPM Instances from an external system such as the Service Bus?
- Does anyone have any examples of a basic XML payload that would initiate a process instance?

I created an process with a message start event and can call it from an external web service call. I can also pass input arguments and map those to process data objects. However I can not find how to return data as response to the external web service call as e.g. the process instance id.
Is it possible to this?

Issue with calling an external web service using web service proxy

Hi,
I've created several web services using JDeveloper succesfully in the past, however I'm getting an issue with one that was working ok previously. Have spoken to the developers of the external web service and they say they haven't changed anything. Also if I test the external web service through soapUI for example it seems fine so it would seem that the issue is with the autogenerated code created by JDeveloper.
Basically I get the following exception as it sends the request to the external service:
java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Bad Authentication header format: 'Basic realm="Integration Server" encoding="UTF-8"'
Expected "," at position 33
The user name/password appear correct.
JDev version 10.1.3.42.70
Any ideas?
Many Thanks
Gary
Edited by: user10916721 on 08-May-2012 09:54

Found the answer. Basically I had one proxy web service working and one not both linking to a middle tier written in web methods. THe issue actually ended up being with the web methods code in that the one web service (that was not working) was put together using a backwards compatability mode. Once this was switched back then started working again in JDev.

Issue when calling an external web service - CRM 2013

Hello everyone.
This is my scenario:
I'm doing a real time data integration from CRM to another software. I deployed several plugins, mostly in create/update messages, for the entities i want to sync. The developers of the other software gave me the endpoint of the web service and I created the
client using svcutil. I manually created the binding and gave it to the generated client, along with the endpoint. At the first tests I could sync some registries, but I had some mapping errors. I debugged the plugin, corrected the errors, and when I
want to tests again, the plugin is throwing me an exception when calls any method of the web service. Let me explain the issue:
The exception:
I instantiated the client for the web service (passing to it the binding and the endpoint). And when I'm trying to call any method (ex. Add), it throws the exceptions "InvalidOperationException". I started to debug the code and I notice that
just before to call the web service method, the state of the client stills in "Opening". Of course that is generating the exception.
The complete exception is: "The communication object, System.ServiceModel.ChannelFactory`1[IAxxisWcfServices], cannot be modified while it is in the Opening
state."} System.SystemException {System.InvalidOperationException}
I did a test, outside the CRM environment, on a console app with the same conditions of the web services client (generating with svcutil, manually passing the same binding and endpoint), and the same order of the plugin code, and everything works well; The
state of the client never stills in 'Opening', so I discarded any problem with the web service.
Anyone knows if I'm missing something in the code? or some configuration?
The CRM is 2013 On-premise with last updates.
Thanks in advance.

I tried adding the web reference in a console app and works fine. In the plugins this can't be done, because the plugins are deploy in database.
I tried another basic test using ChannelFactory. Only want to retrieve some entity through the external web services:
IPluginExecutionContext context = localContext.PluginExecutionContext;
IOrganizationService service = localContext.OrganizationService;
ITracingService tracer = localContext.TracingService;
try
BasicHttpBinding binding = new BasicHttpBinding();
binding.Name = "BasicHttpBinding_IAxxisWcfServices";
binding.Security.Mode = BasicHttpSecurityMode.None;
binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
EndpointAddress endpoint = new EndpointAddress(@"http://*****.svc");
ChannelFactory<IAxxisWcfServices> factory = new ChannelFactory<IAxxisWcfServices>(binding, endpoint);
IAxxisWcfServices channel = factory.CreateChannel();
var entity = channel.FindByEntities(new CRM.Application.Context.Dtos.Asegurado( { CrmGuid = "7C3E96C6-C3BC-E411-80DF-0A736AE14667" }, null, new CRM.Framework.Session() { User = "***", Password = "***" });
catch (Exception ex)
throw new InvalidPluginExecutionException(ex.Message);
That test threw the following exception on the GenericParameterAttributes of channelType of factory object:

[OSB and OWSM] - External Web service stacks and frameworks

Hi everyone ! I'm starting to read about OSB and OWSM and I'm having some doubts. I've some developments of Web services with external Stacks like CXF, JBossWS, Metro and I'd like to ask some questions:
1- Will I be able to productively leverage all features of OSB and OWSM like creating a proxy service to add WS-* standards policies and features (WS-Security, for instance) even with these web services implemented in different stacks other than Weblogic's ?
2- If it is possible, do these web services need to be deployed at the Weblogic server to enable the OWSM and OSB to work effectively ?
3- Even if it is possible to use the OSB and OWSM nicely with webservices developed at external stacks and deployed at other application servers is there any reason to quit using these external web service stacks in favor of Weblogic's (like features only enabled on OSB/OWSM when the services use the Weblogic stack) ?
I suppose that if I ignore the JAX-WS stack from Weblogic and use an external framework (like CXF) I'll lose most of the application server administration capabilities since the Weblogic server won't be able to recognize the CXF stack as it does with its own.But, the main doubt I'm in is, since OSB and OWSM might be used with external providers I probably won't need to develop my web services using the Weblogic implementation (which my team does not yet know) since there will be no features of the OSB and OWSM which can only be used with the Weblogic's stack. I would like, please, to know your oppinions about these considerations. Sorry about the long post and possible errors (I just started learning).
Thank you!

Hi Lupan,
I can speak mostly to OWSM as my experience with OSB is small thus far.
+1- Will I be able to productively leverage all features of OSB and OWSM like creating a proxy service to add WS-* standards policies and features (WS-Security, for instance) even with these web services implemented in different stacks other than Weblogic's ?+
OWSM (10gR3) has two types of policy enforcement point (PEP) -- Gateway and Agent. The Gateway acts as a remote proxy and is neutral to the service implementation technology as long as it adheres to SOAP 1.1. In this regard you can use OWSM freely with CXF, MS implementations, etc. Agents run in-process with the service and thus have far greater restrictions on what service implementation frameworks and containers that are supported. There is some certification for AXIS 1.x running in OAS and Tomcat; but practically speaking, my recommendation for Agents is to only use within OAS 10gR3 where it is built in (and using OC4J Web Services through JAX-RPC).
OWSM 11gR1 initially supports only agent-style (in process) PEP and is built-in to Fusion Middleware and WLS. It is only for Fusion and WLS Web Service implementations.
OWSM is quite full-featured for WS-*.
+2- If it is possible, do these web services need to be deployed at the Weblogic server to enable the OWSM and OSB to work effectively ?+
"No" if using OWSM Gateway PEP. A qualified "Yes" if using OWSM Agent PEP.
+3- Even if it is possible to use the OSB and OWSM nicely with webservices developed at external stacks and deployed at other application servers is there any reason to quit using these external web service stacks in favor of Weblogic's (like features only enabled on OSB/OWSM when the services use the Weblogic stack) ?+
There is the manageability that you mention, but also there is the identity propagation scenario and tight security integration. Both OAS and WLS hosted services in the native stacks (JAX-RPC and JAX-WS) allow sophisticated and secure passing of identity in the request -- for instance, via SAML Assertions in the WS-Sec header -- and built-in capabilities to map the passed identity into the running service's Subject (i.e. enabling JAAS security etc.).
In my experience this type of identity propagation functionality has either been absent or less complete in other typical implementation frameworks not closely aligned with the container security mechanisms.
Hope this helps,
Todd

Hybrid Lync - External Web Services?

Can anyone tell me if the external web services, provided by the on-premise Front-End server are ever used in a Lync Hybrid deployment?
If not, how is "meeting content" that is created in a Lync on-premise meeting accessed by Lync Online users?
Is the content in this scenario shared over media between the Edge servers or is it accessed via the external web services urls (i.e. reverse proxy)?
I'm trying to determine if i need to setup the external web service access from outside (internet) into the on-premise Lync deployment to support a Hybrid deployment, as in this particular case none of the users will be external.

Yes you need it. Even if a Lync user on premises is never external, if they want to invite an external person to a meeting or use mobile client internally, this will be necessary.

Consuming an external web service with WAS 6.40

Hi all,
I know this thread isnt 100% XI forum related, my apologies for that. However, I believe somebody here has experience with this subject.
Im trying to consume an external web service through WAS 6.40 with se80. When I try to create my proxy object package Choose Create > Enterprise Service / Web Service > Proxy Object > URL type, I receive an error message (SPRX084) -> During proxy generation, an interface description in WSDL format is fetched from the integration builder or from another source and interpreted. This WSDL document must describe the whole interface correctly.
I dont have sure, but it seams something within WSDL object/element. Nevertheless, these external web services are working well with other third party client applications, why SAP WAS cant take this WSDL?
Anyone has faced an issue like this one?
Thanks in advance,
Ricardo.

Hi,
some tools do not generate WSDLs correcty (not with all the standards
or with obsolete parts) and then in ABAP you cannot generate a proxy from it
you should be able to see the some more details in disgnosis section
sometimes you just have to change one or two things in the WSDL
and it will be ok for WAS but you need to find the exect cause
of the error - it can be done by debugging

Using Client Side Extensions (SWF) to call external Web Service

Hi,
I'm using .swf files to extend my CRMOD application, and one of my requirements is to be able to show information on a custom applet using the Client Side Extensions. This information is coming from an external system, so i'm trying to call this external web service using .swf.
When i create my swf application and i run it locally, i can access the web service and receive the results into my browser, but when i do the same call from the custom web applet in CRMOD i don't get any results.
Can someone tell me if this is possible? And if so, how to do it?

Authentication : accessing an LDAP via an external web service ?

Hi,
I know it is possible to use an external web service to authenticate a user on a portal.
But I would like to know it is possible for a user to :
- open hiw browser and navigate to the Enterprise Portal
- the portal is asking a user and password
- then the portal call a web service giving the user/password
- the web service (enternal and already existing) check the authentication through the LDAP
- the web service reply OK/NOK to the portal with a SAP USER ID (or another information)
- the portal if authentication ok send a logon ticket to the user
I didn't find any clear information telling it is possible.
So if someone can help on this matter ...
Many thanks.

Hello,
First, thank you Sandor for your answer.
I understand that it is possible to create a BPEL process that exposes multiple operations/messages. This would be exactly what I need: a single process (web service) that will expose many operations. Could anyone, please, point me to such an example?
So far I thought that there is possible to have only one operation exposed with a BPEL process, what is delimited between the receive/reply blocks (in the synchronous case).
