Calling FM in external system from XSLT

Hi,
I know that in XSLT interpreter provided by SAP supports calling function modules.
I need to call FM in external system from XSLT in message mapping and its result insert into one of element result XML message.
Do you think it is possible ?
If so is available any documentation for that.
Any help is appreciated.
Thank you.

Hi Vijaya,
this is very helpfull document for me. However I need some other explanation.
Does it meen that I need to write "Helper java class" ( e.g. in text editor - Notepad) and deploy the source to to Entegration Engine directory or an Adapter Directory ( maybe using Visual Administrator).
It is not clear for me.
I have XI 3.0 running on Windows 2003 Professional so to copy some files to some folders should not be a problem but I need an exact guide what I have to do.
Thank you.

Call to Web Sevice in external system from SAP CRM

Hi,
I have to make a call to External system from SAP CRM 5.0 system. The external system will provide a sample webservice which SAP will try to initiate
Can you please tell me:
1. What settings/object needs to be maintained in SAP in order to make this call.
2. how I can make a call to this Web-Service from a BADI and pass the values to web service and also capture the returning value.
Please explain in detail
Thanks,
Mike

Mike,
You should honestly search the SDN site for consuming web services with ABAP. There are some good examples.
However the general procedure is easy:
1. Generate an ABAP proxy using the WSDL provided to you by the external program
2. Configure an HTTP destination for the server of the web services (needed for HTTPS calls)
3. Configure the logical port for the web service using lpconfig
4. Write the abap code to call the webservice via the proxy. Works very similar to FM call in my opinion.
To expose a webservice(bapi being called from outside) you need to do a little more work
1. Create a web services for the RFC enabled function module via SE80
2. Use wsadmin and wsconfig to make the service available
3. Publish the service out to the UDDI as needed.
Once again this code is pretty well documented in the standard help and SDN. Do a simple search on ABAP proxies and you will find what you need.
Take care,
Stephen

Calling a web service in external system from SRM

Hi folks,
A web service is created in the external system and I need to access this web service from a BADI. Can you tell me how can I call this web service (the external system is giving me a URL) and how I'll get a return. Please let me know in detail.
Thanks,
Prem

Prem,
Hi. You can call the service via HTTP protocol. Pass them values (SET_DATA), and receive a response (GET_DATA), via xml/html.
In your code you would need to create the xml data to pass them, and evaluate the returned xml.
Process...
Data setup
1) Create the XML to send them
Working with the external service
2) Open the HTTP connection
2a) cl_http_client=>create_by_url (IF_HTTP_CLIENT)
2b) lr_client->authenticate
3) Call the to send them the XML
3a) lr_client->request->set_data
3b) lr_client->send
4) Call the lr_client->receive to return the response
5) Close the connection lr_client->close
Data evaluate
6) Evaluation the returned XML and process.
Hope this helps
Cheers
Rob

Need to call up a webservice created in external system from SAP

Hi folks,
A web service is created in the external system and I need to access this web service from a BADI. Can you tell me how can I call this web service (the external system is giving me a URL) and how to capture the return value from the web service. Please let me know in detail.

Hi,
I have the same requirement and have created a new Proxy-Object, uploaded the WSDL file (locally) and Created a Logical port.
In the Logical Port under the tab Call Parameter I've defined the URL of the web-service.
Since I was not able to upload the WSDL by selecting the option URL/HTTP Destination due to error message "HTTP error (return code 400, message "ICM_HTTP_CONNECTION_FAILED")
Message no. SPRX090" so uploaded the file locally.
However, when testing the service, I didn't received a sucess message but:
<CX_AI_SYSTEM_FAULT>
<CODECONTEXT>Local</CODECONTEXT>
<CODE> ERROR_WEBSERVICE_RUNTIME_INIT </CODE>
<ERRORTEXT> Error when instantiating the Web service runtime (Error when initializing SOAP client application: ' error_text' ) </ERRORTEXT>

FTP file on Appserver to an external system from ABAP

Hi,
I am trying to FTP a file that my program writes to the APPSERVER directory. I used FTP_CONNECT, FTP_COMMAND and FTP_DISCONNECT.
I am able to connect to the external system and change to the directory where I have to write the file using cd. The problem arises when I use lcd command to switch the local directory. Although, i specify the path, lcd /usr/sap/icomm/iface/outbound/, on execution of this command, the system points to my C:\Documents and Settings\rkademani\SapWorkDir.
How can I make it point to my appserver?
Further, this program will be scheduled as a background job in Production. I have tried to schedule this as a background job, even then it gives me the same error.
Please help. Thanks in advance.

Call function in external .js from stage.onCompletion

I have my edge composition, and some functions in sim.js
within the stage.onCompletion event, I have:
$("<script type='text/javascript' src='sim.js'></script>").appendTo("#Stage");
how can I call functions, e.g. "testMe()" that are in sim.js from within the stage.onCompletion event?
$("testMe()"); was my first thought, but no. what am I missing?

Lloydie maybe you can help me with this similar problem here (i think it is similar)
I am uncertain that i can use "transform" in edge, transform belongs to jquery.transform.js library. I am particulalry interested in animate({transform:.... to animate rotation and scales.
Can I call the transform.js into the stage like the way you called your custom .js?
Can we import additional libraries ?

Xslt: calling custom Service Application Proxy from xslt

Hi,
Basically, i have creted my custom service application and i wrote webpart to consume it. I have a requirement, to add a button in the SharePoint-Blog XSLTListViewWebPart located in the ~/blog/post/post.aspx page. In this page, they have 2 XSLTListViewWebPart,
and i want to add a button in it to call my service application webservices. I have 2 problems:
a. how to get the target url of my service app because in Custom Service App, it add reference to my AppClientService class in my service app:
using
(SPSite
oSite = properties.OpenSite())
AppServiceClient
serviceClient = new
AppServiceClient(SPServiceContext
.GetContext(oSite));
serviceClient.InsertTest("UserName"
b.
how to integrate the calling of my custom Service Application in the XSLTListWebPart?
Any
article about custom application with xsltListWebpart would be appreciated.
Thank you.
Thank

Calling a secured external web service from ABAP

Hi,
I've created a client proxy from a wsdl to call a secured external WS from ABAP.
The question is: how to pass in the user/password in the client proxy?
thanks

Hi Rika,
have a look to the blog: https://weblogs.sdn.sap.com/pub/wlg/1645. [original link is broken] [original link is broken] [original link is broken] [original link is broken]
Screen shots are "old" but the concepts are already there. Serach the chapter "SAP Side - Setup".
Basically: define your RFC destination via SM59 of type G. There you'll define the target host and the user/password.
Then in LPCONFIG you can specify the defined RFC destination.
Have a look also to http://help.sap.com/saphelp_nw2004s/helpdata/en/16/285d32996b25428dc2eedf2b0eadd8/content.htm

RFC with External system

Hi,
We are trying to develop interface with external system to calculate the shipping costs for a delivery. We will establish RFC connection between SAP and External system.
Do we need SAP .NET connector to send and receive data from/to SAP. SAO shouls act as client and external system as server. If we have to use SAP .NET connectore, can anyone explain me the detailed process of using SAP .NET connector and connecting to external system.If there is anyother way without using SAP .NET connector, i.e by using RFC function modules, can you please xplain that process too. What is the program ID for RFC destination in SM59?
I appreciate your help.
Thanks,
Ashok.

setting the program id you need a person with the knowledge of both the system, with the current input it will be difficult to help with that.
since you are in 4.6C the available options are
1. DCOM connector
2. .net connect
3. JCO
4. or a plain http call to your external system.

Raja

Send price conditions to external system

Hello,
I would like to send the price conditions to a non SAP system. The IDOC COND_A02 seems to be the solution for sending the price conditions modifications to this system but is there a programm to send an initial set of idocs with all conditions (like RBDSEMAT for materials)? I cannot find any.
Thanks in advance for any help provided.
Julien

Julien,
You can send prices to external system from pricing reports, transaction V/LD. For example, I used this to send sales prices to an external system using pricing report 15. Here you can enter your material selection criteria including, condition type. This will generate a report which you can then send to external systems. I apologize, but I do not remember the menu path from the report result off hand.
Ram,
Make sure you have activated change pointers for message type COND_A, create or change a price and excute RBDMIDOC for COND_A.
