How to PI call R/3 RFC without BPM.

Hi Expert.
Why PI direct call RFC probably is not a possibility of doing without BPM.
It makes RFC of separate way, it calling it is made Report program where there is a possibility of doing.
Different adapter where it becomes direct call, RFC piece bay occupational calling there probably is not a possibility of doing.

Krishna Moorthy P, Thank you so much your answer.
I add question.
My scenario is very simple.
Case 1. File to RFC to JDBC Scenario. (Sync)
           Using BPM. PI call File adatper, and PI call RFC Function, and RFC return data send to PI to JDBC.
Case 2. QRFC to JDBC Scenario.(Async)
            Using se37 for back job. So, Back job Function send to PI to JDBC.
In this two case, to what kind of is the efficiency better.
<b>I think that case 2 is performance better case1.</b>
It isn't like that? Krishna Moorthy P
I wating for your answer.

Hi,
I am trying to do RFC to RFC scenario without BPM.but in sender communication channel following error is coming.

How do I call a SAP RFC from an Oracle Form using webutils CLIENT_OLE2?

Hi guys,
Your help on this problem would be greatly appreciated.
We have an older forms 6i application which we are currently updating to 10g (which is a pain itself... but that's a different story.) which currently uses unssupported c++ routines to connect to the SAP system, we want to do away with this c++.
What I have so far is the following test code:
PROCEDURE cmd_summary
IS
o_sap_log client_ole2.obj_type;
o_sap_conn client_ole2.obj_type;
o_sap_rfcc client_ole2.obj_type;
-- o_sap_rfcx client_ole2.obj_type;
-- o_sap_rfc client_ole2.obj_type;
v_args ole2.list_type;
v_logon BOOLEAN := FALSE;
BEGIN
:block3.txt_result := 'TEST Started!';
--create logon control object
o_sap_log := client_ole2.create_obj ('SAP.logoncontrol.1');
--create the function object
o_sap_rfcc := client_ole2.create_obj ('SAP.Functions');
--create a new connection object
o_sap_conn := client_ole2.invoke_obj (o_sap_log, 'NewConnection');
--set the connection properties
client_ole2.set_property (o_sap_conn, 'System', caps$get_sys_param ('SAP_DST'));
client_ole2.set_property (o_sap_conn, 'MessageServer', caps$get_sys_param ('SAP_HST'));
client_ole2.set_property (o_sap_conn, 'GroupName', 'DEVELOP');
client_ole2.set_property (o_sap_conn, 'client', caps$get_sys_param ('SAP_CLT'));
client_ole2.set_property (o_sap_conn, 'SystemNumber', caps$get_sys_param ('SAP_SYN'));
client_ole2.set_property (o_sap_conn, 'User', caps$get_sys_param ('SAP_USR'));
client_ole2.set_property (o_sap_conn, 'Password', caps$get_sys_param ('SAP_PWD'));
client_ole2.set_property (o_sap_conn, 'language', caps$get_sys_param ('SAP_LNG'));
--set up the logon arguements
v_args := client_ole2.create_arglist;
client_ole2.add_arg (v_args, 1);
client_ole2.add_arg (v_args, TRUE);
--run the logon function
v_logon := client_ole2.get_bool_property (o_sap_conn, 'logon', v_args);
client_ole2.destroy_arglist (v_args);
IF v_logon
THEN
:block3.txt_result := :block3.txt_result || CHR (10) || 'LOGON Worked!!';
ELSE
:block3.txt_result := :block3.txt_result || CHR (10) || 'LOGON Failed!!';
END IF;
:block3.txt_result := :block3.txt_result || CHR (10) || 'TEST Ended!';
EXCEPTION
WHEN OTHERS
THEN
:block3.txt_result := :block3.txt_result || CHR (10) || SQLERRM (SQLCODE);
END cmd_summary;
NOTE: the get_sys_param functionis returning text from a table.
This seems to work okay, the logon command returning a TRUE. All good so far.
However, when I try to then use this connection for anything then I stumble and fall!
I've seen an example in VB where the SAP RFC object is "assigned" the connection object by simply stating:
Set oSAPrfc.Connection = oSAPconn
Where oSAPconn is setup in a similar way to my o_Sap_conn in the above example.
I have tried using the CLIENT_OLE2.SET_PROPERTY procedures but I don't think that's quite right.
I've tried using invoke, to try and "run" the method like:
v_args := CLIENT_OLE2.CREATE_ARGLIST;
client_ole2.add_arg_obj(v_args,o_sap_conn);
client_ole2.invoke(o_sap_rfcc,'Connection',v_args);
client_ole2.destroy_arglist(v_args);
but it fails.
I have also tried using the actual Connection function directly:
SAP_ISAPFUNCTIONS.connection(o_sap_rfcc, o_sap_conn);
But that just causes the Forms Server to crash... :?
Has anyone connected to SAP via Forms? I noticed one post on this forum which an example of some code using a SAPBAPI control but not WEBUTIL (Which I think I'd need to use because we are running 10g)
As a side note we are also looking into SAP Adapter as a possible "other" route but this too is getting very complicated... And I can't see a way of connecting a form to the Adpater anyway :(
Any advice would be very much appreciated.

Can anyone help?

File To RFC without BPM

Dear Friends,
My scenario is File to RFC , file is picking from third party and that file parameters are updated in ecc and response is updated in third party system
using XI.
For this one I created data types,message types,message interfaces and message mapping for sender , receiver and response.
In interface mapping I have small doubt i.e how many interface mappings needed for this scenario.
In integration directory how many receiver determination and interface determination needed.
please suggest me.
Regards,
Shalini Shah

Hi Shalini,
U need to create 2 interfaces at sender side(1 is for file request & 2nd for file response) and one interface at ur receiver side for RFC.
Refer File to RFC blogs with out BPM u may find lot of stuff to ur requirement.

File content conversion in File-to-RFC without BPM

Hi,
I am using FCC for file to RFc scenario.
My input record is in the following format:
Header record
data rec1
data rec2
Trailer record..
The parameters are used in File content conversion:
Recordset Name : Header,item
Recordset Structure: Header,1,item,*
key field name : data1
and in additional parameters:
Header.fieldNames            HI,GenDate,Ftype,Fname,Fdate
Header.keyFieldValue       Fname
Header.fieldFixedLengths 1,8,1,50,8
Header.endSeparator        nl
item.endSeparator             nl
item.fieldNames                  DATA1,DATA2,DATA3,DATA4
item.keyFieldValue             item
item.fieldFixedLengths       231,240,241,120
item.lastFieldsOptional       YES
Can anyone check whether any parameters are left, b'cos the file is not being read with this settings. and in the C.C its just showing file processing successfully but not able to see the actual file.

Hi,
I assume you have header, item and trailer structure in source file.
Source Data Type will be as follows.
RecordSet
--> Header
      --> KeyField(Value OH)
      --> H1
      --> H2
--> Item
      --> KeyField (Value OL)
      --> I1
      --> I2
-->Trailer
      --> KeyField (Value OT)
      --> T1
      --> T2
Where Item Strucutre can come multiple times.
Please use following settings.
Recordset name: RecordSet
RecordSet Structure: Header,1,Item,*,Trailer,1
Key Field Name: KeyField
Header.fieldNames: KeyField,H1,H2
Header.fieldFixedLengths: 2,3,4
Header.processFieldNames: fromConfiguration
Header.keyFieldValue: OH
Header.LastFieldsOptional: YES
Item.fieldNames: KeyField,I1,I2
Item.fieldFixedLengths: 2,5,6
Item.processFieldNames: fromConfiguration
Item.keyFieldValue: OL
Item.LastFieldsOptional: YES
Trailer.fieldNames: KeyField,T1,T2
Trailer.fieldFixedLengths: 2,8,9
Trailer.processFieldNames: fromConfiguration
Trailer.keyFieldValue: OT
Trailer.LastFieldsOptional: YES

Async/Sync Communication using JMS adapter without BPM

Hello ,
Pls suggest how Async/Sync Communication using JMS adapter without BPM .
In my scenario I have JMS Sender and then RFC/JDBC as Sync and then again JMS receiver
Pls explain the concept of
JMSMessageID and JMSCorrelationID and how to use it by an example.
Regards

Hi,
If you have selected JMSMessageID, JMSCorrelationID, or JMSProperty and entered a JMS message ID in these fields, you should see the Remove 'ID:' Marker from JMSMessageIDindicator. Set the indicator.
This is necessary because the JMS specification stipulates that each JMS message ID starts with 'ID'. However, this conflicts with ISO-11578.
- JMSMessageID (Uniqueness Is JMS-Provider-Dependent)
(String) The unique message ID. Note that this is not a required field and can be null. Since the JMS provider might not use your provided message ID, the Connector sets a special property called $jms.messageid after sending a message. This is to insure that the message ID always is available to the user. To retrieve this value use conn.getProperty("$jms.messageid") in your After Add hook.
- JMSCorrelationID (Uniqueness Is JMS-Sender-Dependent)
(String) This header is set by the application for use by other applications.
Hope this will help you.
Regards

Async Sync Bridge without BPM (Proxy-Soap-Idoc)

Hi,
I have read some blogs how to do the Async Sync Bridge without BPM for JMS adapters. I have a requirement that I am getting a Async Proxy message to PI and then PI makes Sync Soap call then the result need to send through the Idoc adapter.
Proxy - Soap- Idoc
Here Proxy is a sender so no adapter required in the Config and also Soap is java based adapter and Idoc adapter is a ABAP based so I am not sure this is possible but I just wanted to check with you.
Please let know if this is possible or not?

The mapping programm can be defined as a user defined function. As sample of mine is "getGoogle()", which is doing some kind of address validation. The input parameter URL[0] contains source address. For that you need to import:
org.apache.commons.logging.*;
org.w3c.dom.*;
javax.xml.parsers.*;
org.xml.sax.SAXException;
org.apache.commons.httpclient.*;
org.apache.commons.httpclient.methods.*;
org.apache.commons.codec.*;
org.apache.log4j.*;
Example code for UDF "getGoogle()" is:
String sUrl = "http://maps.google.de/maps/api/geocode/xml?address=" + URL[0] + "&sensor=false";
HttpClient client = new HttpClient();
GetMethod method = new GetMethod(sUrl);
byte[] responseBody = null;
    try {
//      int statusCode = client.executeMethod(method);
//      byte[] responseBody = method.getResponseBody();
//     result.addValue(new String(responseBody));
String sResponse = "initial";
int statusCode = client.executeMethod(method);
responseBody = method.getResponseBody();
ByteArrayInputStream bis = new ByteArrayInputStream(responseBody);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder db = factory.newDocumentBuilder();
Document doc = db.parse(bis);
doc.getDocumentElement().normalize();
NodeList nodeLst = doc.getElementsByTagName("formatted_address");
Node formAdr = nodeLst.item(0);
NodeList nlFormAdr = formAdr.getChildNodes();
sResponse = ((Node) nlFormAdr.item(0)).getNodeValue();
      // Deal with the response.
    result.addValue(sResponse);
    } catch (Exception e) {
      result.addValue(e.toString() + "######## exhrenda - googleResponse:############### URL=" + sUrl+"###########"+new String(responseBody));
    } finally {
      // Release the connection.
      method.releaseConnection();

How to call multiple request to CRM and R/3 without BPM

Hi all
I have a scenario where a SOAP request will come to XI via webservice
I then have to call an interface mapping which has Java mapping in it(the java code is basically calling an RFC in CRM) - then i'll receive the response of interface mapping and send it back to the customer.
Step 2 :The SOAP request which i have received in the first place is to be written as a flat/xml file onto a directory for backup purpose
Step 3: there will be a separate process where the response of rfc will be fed to an IDOC request structure and send to R/3 as a dashboard IDOC.
All this is done without BPM.
So my first problem is "how to write an incoming SOAP request to a file without using BPM?? "
Second I knw that interface mapping can be directly added in Integration directory's Interface determination by making the property as enhanced but "In the Sender Service i write the Business system which contains soap comm channel and in the interface i write the outbound synchronous interface which is the SOAP outbound that hits the xi for the first time But i am not sure what service do i write in the receiver section as Interface mapping is in XI only....theres no other business system or communication channel involved in between."
I really need help...plz help me

Yes abhishek
Client dont want BPM involved as it makes the process really slow
First of all i wanna knw how to use enhanced option in an interface determination....in the ID
as i am trying to load my interface mapping but it says no object found
I am giving you the structure of interface mapping
MI_OB_SAX_MAP (outbound async source interface of interface mapping )
MI_IB_SAX_MAP (inbound async target interface of interface mapping)
MT_OB_SAX_MAP (source message)
JavaClass - test_java/sax_map (Java mapping program)
MT_IB_SAX_MAP (target message
Now when i am trying to configure this in ID
BS__ (Sender business system)
MI_OS_TEST_JAVAMAP (sender SOAP interface)
But i dnt what receiver business system should i select in receiver service ??
as the java mapping is calling RFC inside the code...so no other business system involved
i m stuck.....if u could plz have a look into it

How to Call Same Adaptive RFC across different Backend R/3 Systems

Hi Everyone,
I have been troubled for the last 3 or 4 days on how I should develop Web DynPro code to call the same RFC on different backend R/3 systems. Don't really want to maintain my own Jco connects within a SAP Connector project and I don't really want to import 3 or 4 of the same models. Can someone please inform what is the best approach?
Thanks.

Hi Glen,
There is one other way of doing this which needs a bit of data maintenance.
The webdynpro app will connect to one R/3 backend. In the same R/3 create RFC destinations to all others backends where the RFC's needs to be called. Create a table where u maintain for what value which backend system should be called. Add rfc_dest as an import paramter in all the RFCs in the backend system where the webdynpro app is connected and call those systems using RFC destinations.
For e.g. you have one HR system and multiple FI systems based on Company codes.
Connect your webdynpro app to the HR system. Create a table in the HR system which will contain data like given below
CoCode                        RFC Destination
1000                             RFCDEST1
2000                             RFCDEST1
In the RFC's in HR system add both CoCode and RFC Destination as additional input parameters. From the front end u can pass different values and call the same RFC's from different systems.

Prakash

How do you call a method from another class without extending as a parent?

How do you call a method from another class without extending it as a parent? Is this possible?

Why don't you just create an instance of the class?
Car c = new Car();
c.drive("fast");The drive method is in the car class, but as long as the method is public, you can use it anywhere.
Is that what you were asking or am I totally misunderstanding your question?
