How to use RFC in 7.10?

Hi,
I'm a little bit confused by the help on NW 7.10 SP7. I normally use RFC connections from web Dynpro but this time I have to use RFC from an EJB. As before I tried "SAP Enterprise Connector" which seems to be depricated.
I followed the example how to use Destination Service. It imports "cam.sap.mw.jco.JCO". After correcting one error in the given source (could never run that way), I get the JCO marked as deprecated as well. So this source code there seems to be a left over from NW 2004?
Is the destination service itself also depricated?
So I found out JCO is now depricated and I should use SAP Java Resource Adapter instead. Can I combine it with destination service or is there something similar as in web dynpro? For Ehp 1 I found this adaptive RFC package, but seems not to be available in 7.10?
What I clearly want to avoid is to give any user, password or system parameters in the source code as I'm used from Web Dynpro. Can I use the web dynpro mechanism maybe somehow?
Maybe someone can bring some light in all this
Thx,
Frank

Hi Frank
>After correcting one error in the given source (could never run that way), I get the JCO marked as deprecated as well. So this source code there seems to be a left over from NW 2004?
Not exactly. The deprecation means that the JCo API version is 2.X while JCo 3.0 is already available. However, this does not mean that you cannot use the "com.sap.mw.jco.JCO". I know lots of projects running even on 7.11 and 7.20 that still use the JCo 2.X.
>Is the destination service itself also depricated?
No, no, no.
>So I found out JCO is now depricated and I should use SAP Java Resource Adapter instead. Can I combine it with destination service or is there something similar as in web dynpro? For Ehp 1 I found this adaptive RFC package, but seems not to be available in 7.10?
Java Resource Adapter is just a new JEE container for JCo API. Still it's also has some problems. So I'd not recommend you to use it.
>What I clearly want to avoid is to give any user, password or system parameters in the source code as I'm used from Web Dynpro. Can I use the web dynpro mechanism maybe somehow?
Use JCo 2.X + Destination Service. Ignore the API deprecation.

How to use RFC Function?

hey,experts
I found a RFC function in server A, I want to use this RFC function in server B.
how to use it in server B?
thanks,
kim-heum

Hi,
In system B ,
1)GOTO SM59 tcode.
Then select ABAP CONNECTIONS or R/3 Connections and click on New Connection.
2) Now give the RFC connection name and description. Then in target system give the IP address or hostname and system number and save.
3)Click on logon& security tab and give the language, client , username and password and save.
4) Now click on CONNECTIN TEST button
5) Now it will show the bytes transferred after establishing the connection.
6) go back and click on REMOTE LOGON button.
7) then it will take to other system sap easy access screen if credentials are satisfied.
8) Now go to se38 and create a program
while remote Function module you have to specify the RFC destination name.
eg
call function 'ZRFC_ADDITION'
destination 'ZRFC_CONNECTION'
here ZFRC_ADDITION is Remote Function Module and ZRFC_CONNECTION is RFC to system A.
then it works.
Reward points if helpful.
Thanks and regards.

How to use RFC in OO programming?

experts,
    As far as i know, we can call a function using RFC, such as:
     CALL FUNCTION 'HRRCF_MDL_CAND_OVIEW_RETRIEVE'
   DESTINATION lv_dest
   EXPORTING
     cand_hrobject         = stru_hrobject
     https                 = lv_https
   IMPORTING
     cand_overview         = ls_dataoverview
     messages              = lt_messages
   EXCEPTIONS
     system_failure        = 1 "MESSAGE lv_message
     communication_failure = 2. "MESSAGE lv_message.
Is there any way to call a OO（Object Oriented） method using RFC? I have studied the grammar of CALL METHOD, but i can't find some parameters to assign the destination.
Pls guide me. Thanks.
qiuguo

No, you have to use a function module as RFC. But you can create a custom RFC in the target system with the same input parameters as your method and call the method inside the RFC.
That should do it.

How to Call RFC from PortalService using a ServiceUser

Hi,
I have some code that calls an RFC using JCO.
(I have other code I wrote using JCA to connect from a portlet, but that requires a Session and uses an IProfile)
Our security team wants me to use a Serviceuser instead. But I can't seem to figure out how to use a ServiceUser to call an RFC.
If I can just get an IConnection, i can use the rest of my JCA code to call the RFC. But I'm stuck getting the connection
The closes I've gotten is this:
com.sapportals.portal.security.usermanagement.IUser user = WPUMFactory.getServiceUserFactory().getServiceUser("myserviceuser");
IConnectorGatewayService cgs=PortalRuntime.getRuntimeResources().getService (IConnectorGatewayService.KEY);
ConnectionProperties cp=new ConnectionProperties(new Locale(),user);
IConnection conn=cgs.getConnection("mySAPsystemalias",cp);
There are two problems with this (or maybe more)
The connectionproperties takes an IProfile not an IUser
I also thought I needed a com.sap.security.api.IUser, not the one above.
Can someone point out what is wrong or a different way?
thanks
Chris Buchholz

Chris,
You could always use a JCO JNDI connection, in which case you dont need anything other than a HashMap of the the following properties
client
messageserverHost
systemLangauge
group
type
systemType
systemId
serverPort
username
password
The username and password you supply can be a service user or a normal logon user as far as I know.
Cheers,
Steve

How to use IDOC and RFC adapter in 1 scenario?

We have AAA field and BBB field and we want to send AAA field to receiver sap system using IDOC adapter and BBB field to receiver sap system using RFC adapter. But how to use IDOC and RFC adapter in 1 scenario and how to map and what are the design and configuration objects we require to create?

To achieve this you have to use
Two Interface Determinations
Two Communication Channels (IDOC & RFC)
& Two Receiver Aggrements.
Use the Enhanced Interface determination and give your conditions there. Based on you condition your interface mapping will be triggered and data will be sent to IDOC & RFC respectively.

How to use the exceptions in a RFC ?

I can use XI (through BPM) to call a RFC and get response from the "Export" of a RFC. But could I get the exception from the "exception" of a RFC ?
I tried to write a RFC which will generate a exception and I found it in the XI monitor, but how to use it ? i.e. sometimes I need to get the "export", but sometimes I need to get "exception". Is there any documents or examples for it ? thanks.

Hi,
<i>But for fault message, I don't know how to send it to a receiver.</i>
There is no other configurations that you need to do with respect to fault messages.
If the rfc returns an exception, this message, is passed on to the receiver instead of the response message.
The receiver of the fault message will be the system that sent the request.
<i>(If I can use a transformation to mapping it to other message, I think it's ok too.)</i>
You need not use a BPM, for this, in case you are using it only for fault message handling.
All you need to do is, create a message mapping, with source and target message types as RFC exceptions and carry out a one to one mapping.This would display the exception coming from the RFC as the fault response st the sender.
In case, the exception returned from the RFC is not self-explanatory, you could map constants to the target message type(in message mapping) which would explain the reason for the fault.

Smitha.

I'm not sure what the situation is like for you since I don't live in Australia, but I know that Siri is still in beta and I believe will gain support for more countries and languages as Apple updates it. That's only my best guess, but I might have seen it somewhere. I know Apple is working on support for the iPhone in many more countries by the end of the year.

How to validate the input field data in VC using RFC FM

HI,
Could any body please give me the solution for the following issue?
When ever I enter a value in the input field of an iView, this value has to be validated from the backend BW system. Is this validation is possible using RFC function module?
If yes, please explain me.

Hi Deepak,
U can validate input fields using javascript.Write OnClientClick function for that submit button if ur using htmlb or onClick if u r using html.Refer the follows
http://help.sap.com/saphelp_nw70/helpdata/en/03/900e41a346ef6fe10000000a1550b0/frameset.htm
There are two ways to achieve ur task.
1.By checking for all alphabets.in this u need check all the alphabetic characters one by one.Refer the following
http://www.shiningstar.net/articles/articles/javascript/javascriptvalidations.asp?ID=ROLLA
http://www.shiningstar.net/articles/articles/javascript/checkNumeric.asp?ID=AW
2.By using regular expressions.its very easy and a single line code.here u need to specify single expression for whole alphabets.Refer this

How to use Logical database in function module?

I will create a function module in HR.
but how to use Logical database in function module ? Logical database PNP always show screen.in function (RFC) code , it is a matter.

You cannot attach the LDB to the main program of the function group.
- So you may [SUBMIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=submit&adv=false&sortby=cm_rnd_rankvalue] a report which use the LDB and get back the data (export/import), by default in the syntax of SUBMIT the selection-screen will not be displayed
- Use [LDB_PROCESS|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=ldb_process&cat=sdn_all], fill a structured table for selection, and get data back in another table
- Use [HR function modules to read Infotypes|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=hrfunctionmodulestoread+Infotypes&adv=false&sortby=cm_rnd_rankvalue].

How to use Webservice in Visual composer

Hi,
We have developed a RFC in R3 and converted it into Webservice. We want to use this in the Visual composer. Can anyone suggest some steps how to use this RFC in Visual composer?
I tried the option in Tools--> Define webservice System and gave the following parameters:
new system name = WDP (system name which we use)
new system alias = WDP_VC (system alias which we created)
webservice url = URL of the webservice which we have created and got in WSDL
when we create it gives an error the URL is incorrect.
Kindly let me know if these values are correct and suggest the steps to be followed. Also, if there are any prerequiste steps to be done before using this webservice.
Thanks and Kind regards,
Rajbarath.

Hi,
The option you described refers to defining a new web service system in the portal system landscape. So if you already have it defined - you don't have to define it again.
As for the actual error you're getting, check that:
1. The url is indeed accessible, and points to a wsdl. You can do this by simply inserting it in the browser's address bar and making sure you get a wsdl file in the response.
2. Make sure that you don't need to authenticate, i.e. provide a user and password. Maybe you just forgot to provide these arguments.
Lastly, keep in mind that this 'Define Web Service System' option is just a shortcut. Generally, you would define a web service system in the portal, like any other system, using the web service connector.
Hope this helps,
Lior
