Calling a web service from BusinessObjects Data Services

Hi all,
We are trying to generate a several levels deep structure to prepare the request for a web service call from Data Services. We tried using the Query transformation to map constant values to fields, but as there are nested complex structures, those don't get populated and at runtime we just get an empty request body. We also tried changing the 'optional' and 'occurrence' settings for the structures at every level, but did not help either. Is there any way to create a deep structure manually without getting the input from an XML file or having to create a persistant table, and if we should be using other functions rather than Query step to do so?
Thanks,
S. Gokhan Topcu

Hi
It is possible to map a heavily nested structure. The minimum required to this is a row generation and a query transform. The most important technique is the "make current" option for each level of nesting.
It is one area that be confusing. I have written a couple of white papers that walk through the techniques, they are on the SDN here

Is it possible to call a Web Application from OSB Business Service

Hi,
Is it possible to call a Web Application that has URL - http://host:port/parse.php using a business service in OSB?
What I have seen is it is able to call the service but the data we are sending that is the string in the form of the URL encoded data is not going there. Any help would be appreciated.

Anuj

Problem while calling a web service in BOBJ Data services

Hello Experts,
I am trying to call a web service in bobj data services. A real time job has been scheduled and published as a web service. I want to consume this service in web dynpro java.
I tried both the methods the adaptive web services and depricated version. I also tried calling the url directly and with the metadata and execution destinations.
No matter what I do, I keep getting the following error.
Exception on execution of web service with WSDL URL 'http://XXXXX:28080/DataServices/servlet/webservices?ver=2.0&wsdl' with operation 'SERVICE_<NAME>' in interface 'Real-time_Services'
The call never reaches data services system. If I try to call the service from soapUI (web service testing tool) it works fine.
I am using SAP NW 7.0 SP22 .
Here is my code in dynpro to call the service.
     AdaptiveModel mod = new AdaptiveModel();
     Request_SERVICE_MDM_LOOKUP request = new Request_SERVICE_MDM_LOOKUP(mod);
     Query1 query1 = new Query1(mod);
     Response_SERVICE_MDM_LOOKUP response = new Response_SERVICE_MDM_LOOKUP(mod);
     request.setQuery(query1);
     request.setResponse(response);
     List list = new ArrayList();
     DefinitionsTypes_XsdSchema_1__XsdElement_1__XsdComplexType_Sequence1 element = new DefinitionsTypes_XsdSchema_1__XsdElement_1__XsdComplexType_Sequence1(mod);
     element.setCustomer_Name(wdContext.currentContextElement().getCustomerName());
     element.setZip_Code(wdContext.currentContextElement().getZipcode());
     element.setAddr1("");
     element.setAddr2("");
     element.setCity("");
     element.setCountry("");
     element.setState("");
     list.add(element);
     query1.set$002fDefinitions$002fTypes$002fXsdSchema$005b1$005d$002fXsdElement$005b1$005d$002fXsdComplexType$0023Sequence1(list);
     wdContext.nodeRequest_SERVICE_MDM_LOOKUP().bind(request);
      wdContext.currentRequest_SERVICE_MDM_LOOKUPElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeQueryResponse().invalidate();
      wdContext.nodeSequenceResponse().invalidate();
Please let me know if you have any pointers on how to solve this.
Thanks in advance
Praveen.

have you create the destination?
do you use the wizard to generate code?
usually there is catch clause for this line of code
wdContext.currentRequest_SERVICE_MDM_LOOKUPElement().modelObject().execute();

Is there a way other than redeployment to migrate existing Cloud Services from one data center to another?

We have a need to correct affinity of Cloud Service, Azure DB, Storage and Mobile Services such that they are on a singl datacenter and do not get impacted by network latency when these components communicate with each other. Also to distribute various environments
across different data centers we need to realign some environments to mitigate all environments getting impacted if there is outage.
Existing Cloud Services and related Service Bus queues and topics need to be moved to a different datacenter. Is there a way to do this without having to redeploy cloud services (web and worker roles) or recreate the service bus entities (queues and topics)?
Also, the existing Cloud Service URL need to be retained without with user authentication won't be possible and hence when completed, the new cloud service should have the same URL.
Please provide best available options for achieving this or ask question if more information is needed.

Hi sumeetd,
As far as I know, currently there is no directly way to move services from one data center to another unless redeployment. You could submit a feature suggestion via this page (http://feedback.azure.com/forums/34192--general-feedback

thanks,
Bindu

I am have big headness if some people want to use ETL tool for getting data from EssBASE.
Becouse ETL try export data through all dimension members cross.
if you need export more 1000 recors from Essbase best way do this it's
-> export data with fix statement with using DataExport commnad
-> push text file to SQL with sqlloader commnad (from oracle cmd tool)
And other way - use Essbase Web Services

How to call an Oracle Report from a Self Service HR page.

Hi,
I am trying to call an Oracle Report from a Self Service HR page. I personalized the page to add a button and link the report's URL to that button; but I am having issues passing/manipulating parameters to this report.
Is there a better approach to do this, please post your suggestions. Also If you can direct me to some usefull documentation that will be great.
Any help will be greatly appreciated.
Regards
Hilal

Tapash,
Thanks for reponding.
Here is the URL I am currently using :
https://gccss.glendale.edu:8001/dev60cgi/rwcgi60?server=rep60_crp3+userid=apps/pswd@crp3+report=/u07/oracle/crp3appl/gcccus/11.5.0/reports/US/GCC_ACCRUAL_BAL_0505.rdf+desformat=html+paramform=yes+destype=cache+p_accesscode=""
The p_accesscode is the parameter I need to pass to the Oracle report.
Currently, when I click the button, it invokes the above URL and takes me to the parameter form of the Oracle report and when I enter the Username, it runs the report and displays the desired output. But, what I need to achieve is, to pass the current user who has logged in behind the scene and to get rid of the parameter screen totally. Is this doable ? If yes, please help me !!!
Thanks

Call proxy service from other proxy service with attachment

Hi!
I have got an email sending proxy service I would like to call this from an other proxy service and I want to send attachment in email. I can send email with attachment if i call this proxy as a webservice (e.g. from soapUI)
But if i want to call this email proxy service from other proxy service, the attachment in email is empty. I put a log action (expression: $attachments) in the beginning of email proxy service, and I saw this in the log file:
+<con:attachments xmlns:con="http://www.bea.com/wli/sb/context"/>+
So the attachment is really empty...
I use service callout. I put an insert action in request action of service callout:
In Variable:
attachments
XPath:
+.+
Location:
as first child of
Expression:
+<con:attachment xmlns:con="http://www.bea.com/wli/sb/context">+
+     <con:Content-Type>application/octet-stream</con:Content-Type>+
+     <con:Content-Disposition>attachment; filename="{$v_fileName}"</con:Content-Disposition>+
+     <con:Content-Transfer-Encoding>base64</con:Content-Transfer-Encoding>     +
+     <con:body>{$attachments/ctx:attachment/ctx:body/*}</con:body>+
+</con:attachment>+
Why cannot I call this email proxy service from other proxy service for sending email with attachment?
I tried to solve this other. I called an email sending business service from this proxy service. But in this case I cannot set the body of email. If I put just one Transport Header action in publish action, I could send the email (with empty body). But If I put a replace action in publish action as well then the OSB didn't send the email and I couldn't find any error message in log file... How could I set the body of email in publish action?
Thanks!
Viktor

You should be able to get the current user id from the SPListItemEventProperties object. From here you should be able to create a Claim. For example get the user by using
user = SPWeb.Users.GetByID(properties.CurrentUserId)
SPClaim claim = SPClaimProviderManager.CreateUserClaim(user.email, SPOriginalIssuerType.TrustedProvider, issuerIdentifier);

Calling another ITS service from existing ITS service

Hi to Everyone,
I would like your advice on calling another ITS service from existing ITS service.
From my current ITS service eg. "Z_TESTA", i wish to call another ITS service "Z_TESTB". The problem is that it always prompt for userid and password when i called the 2nd ITS service. However, user already enter the password & id when they login to the 1st ITS service. Is there a way to call this new ITS service w/o the userid & password prompt again?
Below is the codes that we used to call the new ITS service:
(a) "http://.../scripts/wgate/webgui/!?~transaction=z_testb"
OR
(b) "http://.../scripts/wgate/z_testb/!"
We used both method (a) and (b) but same outcome. Thank you in advance!
YanaJ

Hi YanaJ,
in order to skip a manual login you have to have the credentials somewhere. If you disabled cookies, what I told you will not work. Another possibility would the usage of X509 client certificates. But this requires that you have a setup that distributes the certificates of all of your users. I personally nether setup such scenario. Maybe someone other can explain what you have to do.
Best regards,
Klaus

Calling ERP Web Dynpro from CRM Opptunity with parameters

Hi, experts!
In CRM7.0, I'm calling ERP Web Dynpro from CRM Opptunity.
We've added a button in Opptunities and the buttom can navigate into ERP Web Dynpro.It works fine.
Now, I'm trying to move the value of Opptunity ID to a field in ERP Web Dynpro when we push the buttom. That's a problem I want to solve. We're struggling to move the value, but it doesn't work.
We uses the following settings:
1) We call Z- Logical Links generated by Transaction Launcher when we push the buttom.
2) We define Transaction Parameters in a Transaction Launcher Wizard(Step5). We've set "//clipboardBTOrder/BTOrderHeader/OBJECT_ID" or "//datacontextCURRENTBT/BTOrderHeader/OBJECT_ID".
But both of them doesn't get any value.
3) If you set SYST data or constants in Transaction Launcher Wizard(Step5), you can find the data in ERP Web Dynpro.
Does anyone know which parameter gets the value of current opptunity data?
Or if you have any tips to create URLS using programing, could you please share the information with me?
BestRgards.

Does anyone have tips??

Difference Between Data Services Designer and Data Services Workbench

Hello All,
I am new to Data Services .
What is the difference between Data Services Designer and Data Services Workbench .
Am bit confused in the above two .
Please help me to understand the same.
Thanks in advance.
Aisurya

Workbench is used to create, display and modify the objects. It will display the source table data and we can see the logs of the job which we have executed and also we can see the status of a job. In bods 4.2 you can design the dataflow in workbench in previous release we don’t have that option but designer contains debugging option, you can write scripts, it will support all databases; these option are not available in workbench. for more information refer this document:
