Choosing among IDoc, RFC and Proxy

Hi every one,
We have 2 SAP systems, one in the US and other in Kuwait.
The project is in the proof of concept phase. To communicate between the systems, I have a choice to choose among IDoc, RFC and Proxy.
Can someone direct me in this direction.
What are criteria that should be considered in choosing one of the methods of communication.
My other question is that,
there might not be internet facility at the remote location that is in Kuwait. I thought of going for asynch communication...I hope I am right in this.
Please correct me and direct me.
-Naveen.

I guess you should start with the scenarios that you have in hand.
During proof-of-concept stage, you analyze what kind of scenarios that you might encounter in the real-world or during the build stage and choose the technology (RFC/IDoc/Proxy) to prove the end-to-end capability of building an interface.
During the scenario evaluation stage, list out the "out-of-the-box" capabilities of both the SAP systems and come up with a decision tree of when to use RFC, IDoc or Proxies.
Also make sure that you include quality of service and error handling capabilities. In case of IDoc's the error handling capability is all standard and you don't need to build anything from scratch.
I guess these would be some criteria based on which you can evaluate which method to choose from.

RFC and PROXY

Hi all,
i have a standard bapi which is at receiver side,and i neeed to update the data .it is asynchronous.can i use a RFC adapter or should i use proxy here?

keerthi

Hi,
There are advantages / disadvantages for RFC / Proxies / Idocs. Some of the differences are:
RFC and Proxy:
RFC/BAPI has its own overhead of function call.
Proxies communicate with the XI server by means of native SOAP calls over HTTP .RFC does not, so you have to convert from SOAP to RFC calls and vice versa. So XML conversion is required.
ABAP Proxies uses Webservice and Http Protocols.
If you use ABAP Proxy , you can reduce the overhead calling the function again and again.
Proxy and Idoc:
IDOC : After recieving the strucutred data It processes it using a Function Module associated with it.
Proxy : Proxy is a structure where there is no processing function module associated. You need to explicitly write the Business Logic/Call the subroutines here

RFC or IDOC or ABAP Proxy

Hi,
What is the best way(R3 Side) for standardization?
R3 <-> Legacy.
I've read all related article on sdn, but i am not still clear on which best way RFC or ABAP Proxy or IDOC in real life.
if you are, what is suggestion?
thanks

This is my absolutely my view. Another guy has his own response. So first go through your requirements and then you can decide for what to go.

IDOC and Proxy

Hi friends,
I am having a doubt regarding IDOC, RFC and Proxies.
Now-a-days in real time ,which are in use IDOC Adapter or proxies....
in case of communicating between two SAP systems.

Hi raju
Adapters
 Connect existing (legacy) systems to XI
 Specific wire protocol
 Interface semantics externally pre-defined
Outside-in development approach
Proxies
Connect new SAP applications to XI
Native connectivity to Application system (adapter-less)
Interfaces designed centrally in Integration Repository
Inside-out development approach
c) RFC adapter- Remote funtion call maps RFC to Xml message and viceversa
In XI 3.1 we can use RFC.
>= Netweaver AS 6.2 we can use proxy in XI
Proxies are mostly used to communicate with two SAP system

Idoc,rfc,proxy

We can add a Idoc metadata for Idoc by using idx2, In the same wise how can add metadata for a RFC and proxy?

Hi rocksrahul ,
We can add a Idoc metadata for Idoc by using idx2, In the same wise how can add metadata for a RFC and proxy?
Idoc: yes correct we can add a Idoc metadata for Idoc by using t.code u201CIDX2u201D.but we donu2019t need to load any meta data for Rfc and proxies.
RFC:
In ESR, we can import RFC under imported objects.
Proxy:
We donu2019t need to import or anything for proxy but we need to generate proxy by using t.code u201Csproxyu201D on sap r/3 system.

RFC vs Proxy

Hello ,
We are working on JDBC to RFC scenario in SAP XI,
We have to do
huge functionality like calling Two standard Transaction working on two BDC programs and Creating the Log errors and additional performs in side the RFc.
IS it advisable to do like that..
Or better to use Server proxy.
If we use server proxy what are the advantages and issues in this scenario.

difference between RFC and Proxy :
*proxy is always better than RFc in many cases *
Proxy Supports Synchronus and asynchronus Communicatio .
proxy it is used to procees the Mapping and rooting on Integration Enginee bypass th Adapter Enginee so it will improve the performance.
dont need to create Sender Communiv=cation Channel and Agreement in ID .
proxy support more than 5 MB.
proxy is used to control Application, Sysytem Error.
supports Ackonwledgements
supports Attachments
but if u want to use Client Proxy then need to write REport.
Rfc :
RFc Supports Synchronus and asynchronus Communication.
Dont need to write any Repotr.
need to create Communication channels in ID.
RFC Adapter :

IDOC,RFC,BAPI

Hi all,
I need some good documents on IDoc,RFC and Bapi.If any one is having please provide.Thanks in Advance!!!

Hi Das
IDOC ---> Will be used to sending data in Async mode ...
It is very standard and for better performance Async case
RFC --- > Function module and general will be used to make call to function
sending the function (XI has RFC adapter)
BAPI ---> Other version of RFC (Objected oriented) mostly we will use for Sync
calls (Mostly in XI using proxies we will call BAPI's)
Please see the below links

What is the main diff between the IDOC, RFC,PROXY

HI,
May i know in witch situation we will go for : 1) Idoc
2) RFC
3) Proxy.
i hope we use above three are for posting data in R3 system.
can any one please clarify when exactly we use witch adapter.
regards

Hi
IDoc
It is used only for data transfer.It lies on ABAP Atack.also the underlying protocol is tRFC.
RFC
It is used when you need to process data and return values to remote system.That is it is used in synchronous scenarios.It lies on J2EE/Java Stack.It is not a data container like IDoc.It calls a functional module which gets executed.The underlying protocol is HTTP.Communication is done suing JCO/JCA.
Performance wise IDocs are better.
Proxies are used when large amount of data is involved.
Also go through this.

IDOC Adapter and RFC Adapter

Hi experts,
Q1. What are the configurations steps (Transaction codes) required at R/3 and XI while sending the IDOC to XI? Please provide the list of TCodes required at both sides. if any weblog is exists which provides detail explanation on IDOC scenarios plz provide the path.
Q2. While sending the IDOC we need to generate partner profile and port. How many types of port exist and wht each port represents?
Q3. In RFC Sender Adapter we need to create RFC port in R/3 and there we specify Connection type as T which TCP/IPwhy we use connection type T instead of 3 (which represents connection type as R/3). While communicating with SAP systems we need to specify the connection type as 3.
Q4. How many types of partner profiles exist and wht each type represents?
Q5. How to transport design, configuration objects and SLD objects from Development system to Quality system. Please provide me the steps to transport the objects?
Q6. Once the objects are transported a .tpz file is created wht is the purpose of the file and where it will generated? Suppose if Ive transported the namespace from Dev to Quality system then at quality side to which SWC this transported namespace is assigned. Do we need to create any SWC at quality system side?
Cheers

BS for Third Party (Logical system):-Enter the XI logical system name.
In Transaction SALE
Define and Assign the logical system name.
2.& 3 ) for the 2nd question the answer was in above u need to create the partner profile and port.
port can be created as HTTP Port and RFC port which are used to communicate with the R/3 server and depends on the requirement we need to choose the port..
4. partner profile creation depends on ur scenario, it is a custmized one it purely depends on the customer requirement, there is no specific partner profiles exists in R/3.
5. For transportation u may choose File level transport or CMS, if u trnasfer through File level it is very easy to maintain and reimport in the production server,, just while exporting from the development server a .TPZ file was created and import this .TPZ file in the production server this gives the entire objects of IR and ID, but when u deal with SLD instead of .tpz there u will be creating .zip file, so u neeed to reimport the file in the production server..
6. The .TPZ file will be created when u export the objects either in IR and ID..., so as i explained in the above point it will go top the export directory of development server and import in production server with IMPORT directory..

Kishore

Why is a sender communication channel not required for IDOC and PROXY ?

Hello,
In case of IDOCs, metadata will be available in PI for the IDOCs used both at inbound and outbound.
Why is a sender communication channel is not required in case of IDOC and PROXY outbound scenarios (i.e. IDOC to File or PROXY to file ..) when a receiver channel is required for scenarios like file to IDOC or file to PROXY.
Though this might be a regular question, I am not able to find a proper reason.
Please let me know the reason for the above request.
Thanks & Regards.

You will create RFC destination in ECC , it will have details about PI system details, when ever you send IDoc, ECC will use Port and RFC destination to connect PI Integratiion engine to deliver data to PI.
But when receiver side you will create RFC destination in PI with ECC details, but to call RFC destination and Port we need medium that was the reason we create IDoc communication channel.
Even the same case for Proxy also, but HTTP deastination establish the conection between ECC and PI, but receiver side you have to create XI channel with PI integratioin engine adress to post data.

Raj

RFC , IDoc , XI and JDBC receiver communication channel--- Good Design

Hi Experts,
We have developed around 60+ interfaces on PI7.1 EHP1, in that 20 interfaces sending data to Data Base using JDBC receiver communication channel, 15 interfaces ABAP inbound proxy using XI adapter,10 Scenarios using IDoc receiver channel and 15 scenarios using RFC receiver channel.
But I have created only one IDoc, XI , JDBC and RFC channel.
Is it right idea/design or do I need to create more channels to handle multiple request.
Please share your thoughts on this.
Regards,
JAM

Hi,
For XI,RFC and Idoc when it's pointing to one SAP system you don't need any further comm channels.
For JDBC , if you are pointing to only one database you can use the same channel, if the target/databse changes you need more comm channels.
Your Design is as per the standards.

What is RFC and IDOC Adapters in XI ?

Hi,
What is the RFC and IDOC Adapters in XI , in which scenarios we use this adapter , what is the advantages and disadvantages of RFC , IDOC ? can any help me out.
Thanks & Regards
Surendra M

Surendra,
What is the RFC and IDOC Adapters in XI :
IDOC: Generaly standard IDOCs are used to update the data in R/3 or to extarct the data from R/3.
RFC: Are generally used for synchronoue scenarios.
in which scenarios we use this adapter
For example you can use the IDOC ORDERS05 to post the sales orders.
Similarly you can use BAPI_COMPANY_GETDETAILS to fetch the company details.
what is the advantages and disadvantages of RFC , IDOC ?
Advantages: Both can be used for data retrival and posting. RFC can be used for synchronus purpose but IDOCs are always asynchronous.
Disadvangages: If you are using custome made RFC/IDOC then you have to import the RFC/IDOC into XI every time when you make any small changes in the structure.
Also go through this blog to choose the right adapter to integrate with SAP systems.

Regarding rfc and idoc sender

hi
   can any one provide me with some scenarios having
idoc and rfc as senders.

Hi
To Configure the RFC to FILE scenario ,Proceed as Follows
a.       Create an RFC Destination to XI in transaction code (SM59)
b.       Create new destination of type T (TCP/IP)
c.       Make sure you select Registered Server Program option before writing your program ID
d.       Write you program ID (remember it's case-sensitive)
e.       In the gateway host and gateway service write the values of your Application system - business system (not the XI server)
             Step2:Repository
1)       From the Integration Builder page, select Integration Repository. This will launch the Java Web Start Application. Log with the User id and password from the Integration Server
2)       Choose Tools->Transfer from System Landscape Directory->Import Software Component Versions
         From the list of Software Component Versions, Choose your own software component version .Click Import.
3)       On the left hand side frame ,software components will appear .Select your own software component. Open your own software component. Double click on this software component. A screen will appear .Switch to display mode. After doing this first add a namespace under Namespaces.
         The namespace is ur:rfctofile
4)       Then choose the Radio Button ->Import of RFC AND IDOC interfaces from SAP systems permitted
         After this specify the connection parameters to the R/3 system:
4.1)     System IS :sapfox
4.2)     Client IS :800
         Then Save it. The new namespace will be visible under software component version node in the left frame.
         Under the namespace node, you will find the section Imported Objects. Right click on it and choose Import of sap objects. A wizard will display. In the wizard provide the following details.
4.3)     Application server:172.25.5.7
4.4)     System number: 00
4.5)     User name:developer
4.6)     Password: Password of Sap R/3 system.
         Then click continue .You will find IDOC and RFC node. Click on this node and select the   Idoc or Rfc which is to be imported from R/3. Click Finish to start the Import. Close the wizard. After doing this the   Rfc and Idoc will be available into XI as Message types. So no need to create any Rfc or Idoc Structure. We need to create a structure for file only.
5).      Under your namespace in the left frame, expand the node Interface objects. You will find a node DATA TYPES
6)        Create new data types.
6.1)      Right click on Data types and select New.
           Your Data Type is. dt_file
          In the data type Editor ,Create a structure having Elements of type String , integer, Boolean , Float etc as per the requirement.
          Save the object.
6.2)      The Import function for XSD files enables you to upload message definitions from external sources. The object type External Definition is a container to make external definitions available in the Integration Repository.. While Importing the XSD files from External Definition
          no need to create Data types. They are imported directly as Message types.
6.3)      To do so, In the left hand frame Under Interface objects Create a new object of type External Definition and give name to it.
          Select the following.
6.3.1)    Category: XSD.
6.3.2)    Messages: From All Available Global Elements.
6.3.3)    File:
          Once the XSD is imported, click on Message tab , You should be able to see 2 messages(Request and Response)
7).      Create a new Message Type.
7.1)     In the left hand frame under Interface objects, right click on the Message types and select new.
7.2)     Give a suitable name to the Message type.(MT_ messagetype).
7.3)     For the section Data type used you can go to input help (F4) or Search help provided and choose your data type (DT_datatype) from there.
         Save it.
8).     Create a Message interface
8.1)    In the left hand frame under Interface objects, right click on the Message Interface and select new and name(MI_ messageinterface) it
8.2).   The interface Should be Inbound and mode should be Asynchronous .It should reference your Message type(Use F4 or Search help).
        Save it.
9) .    Create a graphical mapping between the target document and the sender .
9.1)    In the left hand frame ,expand Mapping objects. Right click on Message mapping and name it.You are now in a graphical editor.The Source message is on left, the Target message is on right.
9.2)    As Source message select your own Message type.You can choose Search for Integration Object.As a reminder you can find your Idoc or Rfc under Software Component- >     Namespace->Imported Objects.
9.3)    As Target Message you can choose your Rfc .Choose Search for Integration Object.
9.4)    Now that we have defined the Source and Target message, we can start defining the Mapping rules.
9.5)    Map the fields of Source document to the equivalent fields in Target document .This can be achieved easily by locating the field in Target document and then Drag and Drop the   Source fields to the respective Target Fields.
