Difference between building/consuming web service in ERP vs. XI (PI)

Hi All,
Can someone direct me to the pros and cons of whether to build/consume a web service in ERP (ABAP - SE80, etc.) versus in XI? We have ECC 6.0 and the latest version of Web AS running - so no issues with that. I'm just wondering - if we can build and consume everything in ERP, why even waste our time with XI (for web services)? What gives?
Thanks,
Matt

Hi there,
There are three main aspects in using XI for Enterprise Services:
1. The ESR - Enterprise Service Repository (based on Integration Repository)
2. The Service Registry (coming as part of latest XI release: PI 7.1)
3. The need for asynchronous services
1. The ESR
This one should be used for designing your services -ESR is design-time-, defining object data model, interfaces, operations and so on based on Global Data Types.
The use of Global Data Types allows to ensure that when we speak of e.g. an amount being 1,000.52, it will be understood correctly from the other side thanks to a common set of data types.
Furthermore, the ESR comes with pre-defined content (interfaces and others) that makes the building of new services faster.
Note that once you've defined your service in XI, you'll have to generate a proxy (ABAP or JAVA) in your ERP (in case ABAP) where you'll need to implement your code, this means that at run-time your're not obliged to pass through XI to run the service.
2. The SR
The Service Registry is the ultimate place where all enterprise services of your company will be published. This will really be your ES yellow pages where you can get services WSDL and location so that you can integrate them easily in any of your applications. Services available in the SR are (should) be "released" services, so in contrary to what you can find in the ESR (where you can have work in progress), here you'll only have services that are completed and ready to use.
3. Asynchronous ES
The ERP does not allow you to create real asynchronous services, and this is true as well when you call a service from your ERP as when you provide a service in your ERP to external calls (proxy client).
In case you need to work with asynchronous scenario, you'll have to go through XI.
Of course in an ERP system, there are many ways of making a "kind of" asynchronous behaviour with coding, workflow and so on, but in this case the other party (the external service provider or caller) will probably have also to be adapted which is not always possible.
Well, these are from my point of view the most important elements; so, if you don't need asynchronous behaviour and you don't have to many services to manage you can certainly work without XI.
Now, if you start having services from different systems, and you build a complete enterprise SOA based infrastructure, XI/PI becomes a necessity.

Difference between Direct binding , Web service Adapter and HTTP Binding

Can any one help what is the differnce between
*1) Direct binding*
*2) Webservice Adapter*
*3) HTTP Binding*
I am trying to use the above service adapters as references in BPEL.
I had invoked a web service hosted in OSB from BPEL via web service adapter and was successful
On going through few docs came through the other two service adapters but was not able to figure out what exactly is the differnce .
I learnt +"*Direct binding*"+ can be used to call OSB+ . How does it vary from Webservice Adapter+

hi Eric ,
Thanks for clarification ..
OSB does not generate WSDL and web service adapter in BPEL mandates WSDL .
I had to create WSDL separately and then feed into Web service adapter in BPEL to call OSB Proxy service. Though successful , felt its not an better approach.
Please advice is there any way thatWSDL is generated in OSB itself . .if i try to create webservice on Proxy service the wsdl resulted from it has only binding and porty type .
Is it the same case for ++Direct binding++ .I assume it should not be the case

Complete newbie question - Can BI consume web services?

Post Author: Steve Lamont
CA Forum: Data Integration
I am working on a new client site working on integration between a whole slew of systems including CRM, billing, BI etc. The client is architecting a SOA oriented approach to all integration where it make sense. As part of the effort, a new BI database is being built and loaded via some ETL tool. The primary interface to access this new BI data will be business objects (BO). Now, in the current environments, there are multiple, disparate BI systems containing various data. The BO knowledge person (and he is not a business object employee) on this site is claiming that to access these other BI databases, he wants to do it by sending out requests via service calls. I fully understand that BO itself can be set up to be a service provider and provide services for other consumers to take advantage of, but how does BO itself consume services provided by other applications?
Obviously I don't fully understand BO, but my initial inclination is that this approach is wrong. If data is required from these other BI source, wouldn't they be configured as data sources within business objects? This BO guy claims that calling web services is more efficient that direct peer-to-peer calls via the database drivers.
Can any share some comments on this situation?

You posted your question to the wrong forum, please try to post it to one of the subforums in "Enterprise Reporting, Query & Analysis".
This forum is about Data Integrator, Business Objects ETL tool.
I'll try to answer your question anyway with my reporting background From what I know, YES we can consume web services in reports (Crystal reports), but for larger volumes of data a direct access to the database would be faster. A webservice approach might make sense if the webservice implements some business logic (semantic layer) which would be easier then to go directly to the tables.
And just for the record : also Data Integrator can consumer web services...

Error consuming Web service from an ABAP Program

Hello guys,
I'm trying to consume a Web Service that is exposed in the internet. The conecction to the Web Service its via SSL.
I'm having a problem at the moment I call the web service from my abap program. But I'm able to test the same web service, from the SE80 tx with out trouble.
I have identify that there is a difference in the SOAP envelope, that its received in the Web service, when I call it from the test enviorment and when I call it from the program.
This is how it is received from the TEST tool (a succesfull call of th WS) :
<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">

What's the difference between all these web ide versions?

Hi guys,
I'm an sap internal employee. I want use web ide for developing UI5 application. But as always, SAP delivers a tool with various versions.
What the hell is the difference between the following web ide versions?
https://webide-xxxxxxsapdev.dispatcher.neo.ondemand.com/index.html
https://webide-xxxxxxtrial.dispatcher.hanatrial.ondemand.com/
https://rde-fiori.dispatcher.neo.ondemand.com/index.html
I once saw one of my colleagues using some kind of drag and drop functionality building a xml view user interface.
But I cannot find that feature in all the above ides.

The first one & the last one are in the neo landscape which is only available internally. I guess the last one might be deprecated as the name rde is changed to webide long ago.
The one in the hanatrial landscape is the public developers version available.
Drag & drop - There is a layout editor available to design the views. You just have to right click on your XML view & choose open with layout editor. I believe that should be avail in all those webide's.

Best practice for consuming web services

Hi
we are consuming web service in orchestration by "Add Generated Item".By using this option it creates 1 orch,1xsd file and some bindings.
we have different projects for schemas,maps and orchestration under our solution in visual studio.
Now i need to know that what will be the best practice for consuming web service in orchestration i mean in which project should i use "add generated item" (in orchstration project or in schemas project) coz it generates both 1 orch and 1
schema.
thanks

From a service orientation perspective you should abstract the service artifacts from the other artifacts. Otherwise it will be very difficult to update the service interface without affecting the other artifacts. For example you don't want to have to redeply
your entire application if only one field changes in the service you consume.
So I typically generate the items, remove the unnecessary stuff, and put them in a separate project.
Depending on the control you have over the services you want to consume, it would even be better to create another layer of abstraction. By that I mean create your own interface (schema) and map that one to the one the service exposes. This basically
is only necessary if you consume external services that are beyond your control. By abstracting the interface it exposes, you limit the impact of changes of that interface on the rest of your system. All changes are abstracted behind your own interface.
If you consume internal services, you can probably control the way the interface is defined. In a service oriented world all internal services expose a well known interface, based on the domain objects you have within your organisation.

Hi,
Activity means e.g.. sales call, customer visit etc.
But service process means after you sale your product if some service related issue arrives then that is taken care by this transaction.

Windows authentification while consuming web service from ABAP

Hi All,
We are consuming web service from ABAP, we have created client proxy in SE80 and configured logical port in LPCONFIG.
This one was working fine. Now we have added windows user authentification to access this service.
Now when I'm trying to regenerate this proxy in R/3 it is asking for user and password. When I enter these details this one is not working.
If I access this service direcly from internet explorer and I enter same user and password then I would able to access this service.
Could you please let me know how to handle this.
Regards
Vikram

The dialog that is produced by HTTP Destination object of the logical port is designed only for use within Classic Dynpro applications. There is no prompt produced when running in Web Dynpro. If possible assign a generic user within the logical port definition and this will be used automatically by all users.

Consuming web service in PI 7.3 and creating file

I need to consume web service in PI 7.3 and create file from response. I have WSDL for the web service. Now confused about datatype/message type. Is there any document/note to follow?
==>
Hi,
There are 2 ways you can do this :-
If your sender is a file and receiver is a webservice and you want to map the response back to the file then :-
Sol 1 :- Async-Sync Bridge using RequesResponse Oneway bean
Sender File channel ---> Soap Receiver Channel
Soap Receiver Channel brings the response back to the File Receiver Channel.
Now this File Receiver Channel should be called inside the Sender File Channel using the above bean.
Data Type :
Src - File struc to SOAP request (WSDL used as an external definition)(mapping 1)
SOAP response(WSDL used as an external definition) to Tgt File Struc (mapping 2)
Sol 2 :- Async Scenario
Make a Sender File Channel --> use SOAP lookup channel (pass the request payload through the SOAP receiver channel) --> Map the response back to the File using File Receiver Channel.
Data Type:
Src - File struc to Tgt File Struc (mapping 1). Since you are passing the request payload through SOAP lookup in the UDF itself.

Consuming Web Services with ABAP - WSDL

Hi All,
I Want to consume web service in abap, i found lot of documents,Here i am having data in the internal table i need to pass

I found the input and output, Where i can find the method generated or we need to create it
CALL METHOD io_clientproxy->XXXXXXXXXXXX
please let me have your valuable ideas

I have not heared about SPROXY, Here i found some code,which calls a web service method and where it is from.
when i double click on my proxy it shows me some method.IF_PROXY_BASIS_INTERNAL~CREATE_FRAMEWORK
this is the one web service method. and i meed to pass the internal table data to WSDL file.

To consume web service in ABAP is it required that server should be XI.

Hi ,
I am trying to connect to a webservice from netweaver 7.0 systemand it gives an error " Not configured as integration engine". Is it required to have integration engine to consume web service.
Sanjay

Hi Sanjay
You can consume webservices in ABAP but its better to use XI in mid to avoid point to point communication. Using XI you can have a central hub for all services you consume or publish

Which tools build a web service application

i am a greenhorn in web services.
i want to build a the example " <INSTALL>/javaeetutorial5/examples/jaxws/helloservice/"
This are the steps am following
-open the cmd prompt;
-type cd C:\Documents and Settings\Guest\Desktop\francis\sun\tutorials\jwstutorial20\jwstutorial20\examples\jaxws\helloservice
-type asant build
i get the message : asant is not recognised as a batch command.................
i get the problem is that i have not set the classpath, but i need to now what builds the web service application or the directory which has the tool.

If you want to create web service in java then you can use Apache Soap or Weblogic web services using EJBs.
