Difference between RFC adapter and a proxy

Can any one tell me the technical difference between RFC adapter and a proxy?
reg

There are advantages / disadvantages for RFC / Proxies / Idocs. So if I am in your position depending upon the requirement I will choose one. 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
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.
Also go through this urls which may help you:

Difference In RFC Adapter and XI proxy

I am using RFC adapter for master data and XI proxy for transaction data , can anyone tell me what is major difference and what is negative point in using RFC adapter
Thanking you
sridhar

Hi,
Adapters enable the Integration Engine and the Partner Connectivity Kit (PCK) to communicate with different applications.Adapters connect the Integration Engine to SAP legacy systems, as well as to external systems.
In this way, adapters integrate existing SAP components with SAP Exchange Infrastructure, for example. In the process, XML and HTTP-based documents are converted to IDocs (IDoc adapter) and RFCs (RFC adapter) and the other way around. This enables you to integrate your existing SAP infrastructure with the new SAP infrastructure, which is based on system integration and the exchange of XML messages.
The plain HTTP adapter gives application systems the option of communicating with the Integration Engine and exchanging business data in a simple format, using an HTTP connection.
RFC Adapter :
The RFC adapter enables you to use the functions of the Integration Engine or the PCK in existing SAP landscapes. It is used by SAP systems to connect to the Integration Engine or the PCK by using the RFC interface. It supports SAP systems as of version 3.1x.
For FAQs about the RFC adapter, see SAP Note 730870
The RFC adapter is provided by the Adapter Engine and the PCK. It essentially comprises two parts, namely a sender adapter at the Integration Engine inbound channel, and a receiver adapter at the Integration Engine outbound channel.
The adapters are configured in the configuration part of the Integration Builder, or in the configuration part of the PCK. You use the SAP Java Connector (JCo), which enables you to manage metadata. This in turn enables you to map RFC data generically to RFC XML and the other way around.
The receiver RFC adapter can be used for mapping lookups.A communication channel with a receiver RFC adapter can be created automatically for business systems that are defined in the System Landscape Directory.
The RFC adapter maps the following RFC calls to XML messages and the other way around:
Synchronous RFC calls (sRFCs) in messages with quality of service Best Effort (BE)
●     Transactional RFC calls (tRFCs) in messages with quality of service Exactly Once (EO)
●     The receiver RFC adapter can also process messages with quality of service Exactly Once In Order (EOIO). They are mapped to transactional RFC calls (tRFC).
You require the sender adapter if you want to use the Integration Engine or the PCK to process RFCs. The RFC adapter converts the incoming RFC data to XML message format (RFC XML) so that it can be processed by the Integration Engine or the PCK.
You require the receiver adapter if the determined receiver system expects the data from the Integration Engine or the PCK to arrive in RFC format. In this case, the Integration Engine or the PCK must transfer the received XML message (RFC XML) to the RFC adapter. The RFC adapter converts the RFC XML message to a valid RFC call and executes the call.
Proxy :
Generally speaking, interfaces are where functions in a system can be executed. In the context of SAP Exchange Infrastructure, only the following interfaces are relevant:
·        Interfaces designed for message exchange between application systems
·        Interfaces used by a cross-component integration process to receive or send messages, or both
Starting with a cross-system integration process, you can then derive the corresponding interfaces required. SAP Exchange Infrastructure supports this process by using an integration scenario to describe the collaborative process. The integration scenario summarizes the interfaces required for this collaborative process.
You can use SAP interfaces that already exist in systems, non-SAP interfaces that are connected to SAP Exchange Infrastructure using adapters, or define new interfaces called message interfaces in the Integration Repository. Both worlds can also be interconnected in a collaborative process.
Interfaces are an essential component of SAP Exchange Infrastructure:
·        You define the interfaces to be used in an integration scenario.
·        Cross-component integration processes use interfaces to exchange messages.
·        You define the XML transformations for messages that are to be exchanged between two interfaces in a mapping.
·        You assign an interface in a sender system to one or more interfaces in a receiver system in logical routing.
·        You generate proxies to implement your scenario based on message interfaces.
You save interface descriptions (message interfaces, BAPIs, RFCs, and IDocs) in the Integration Repository so that they can be referenced throughout SAP Exchange Infrastructure. However, adapters for external systems do not normally use interfaces; instead they access files or database tables in order to function, for example. For this reason, it is not necessary to import these interfaces into the Integration Repository. If the structure of the message is described using a WSDL, XSD, or DTD schema, you can import the schema as an external definition.
Hope this will help you.

Configure XI adapter for abap proxy scenario- plz help

Hi,
Pleas help me in configureing the XI adpater in abap server proxy scenario, answer the one in bold in below
Scenario is asynchronous
Http -> XI ->R/3(abap server proxy)
sender: Through http client
receiver is abap server proxy
Repository objects:
Sender: sender_DT, sender_MT, sender_MI(outbound asynchronous)
Receiver: receiver_MI
Interface mapping: source=sender_MI, receiver_MI.
Proxy generated on R/3 client 550 for receiver_MI.
this proxy internally calls an RFC which inturn updates a table.
Configuartion objects:
Sender: business service, no comm channel since http sender.
receiver: R/3 business system
Comm channel: receiver_cc type of XI.
transport protocol: http
message protocol : XI 3.0, since both XI and R/3 on webas 6.4
addressing type: URL
target host: ??? where can I find this
service number: ?? where can I find this
path: /sap/xi/engine?type=entry i guess the path is correct for XI 3.0
My system details: XI - client 400, R/3 client 550.
Authentiction data:
user name: this user suppossed to be from R/3 or XI?,
passwrod; proper password
logon client: the client supposed to be of R/3 or XI?
Recevr determinaion, interface determination and recevr agrrement looks fine.
Please reply , your help is appreciated.
Thanks
KK

Hi,
>>>target host: ??? where can I find this
Your R/3 host number you can find System->Status
>>>service number: ?? where can I find this
You can find in SMICM in services
>>>user name: this user suppossed to be from R/3 or XI?,
passwrod; proper password
logon client: the client supposed to be of R/3 or XI?
R/3 logon details.
Thanks,

SOAP/HTTP adapter for ABAP proxy

Hi,
Is it possible to send data to a SAP system using an inbound proxy and SOAP/ HTTP adapter.
As per my knowledge , XI adapter is generally used for Proxy communication.
If SOAP/HTTP can be used then what should be the message protocol.
There are 2 protocols allowed by SOAP adapter : SOAP 1.1 and XI3.0.
Can XI 3.0 be used here?

1. you will increase the burdon of message to include header and body with SOAP/HTTP
Use following link to decide which adapter should be used - http://www.sdn.sap.com/irj/sdn/index?rid=/webcontent/uuid/70d8e250-e892-2b10-ab8a-d04433cf158b [original link is broken]

Use EOIO on Sender RFC and outbound ABAP proxy calls

In the comm channel of SOAP and FILE there is a simple flag to set for QOS = EOIO
In Plain HTTP adapter a QOS parameter can be supplied.
IDOC uses control record tricks or a Receiver adapter option.
But what about the RFC and XI adapters.
The docu states QOS of EOIO for RFC and XI adapters is possible.
How is set for sender RFC and Sender XI adapters?
regards
Phil

Phil,
I was discussing with Michal about this.
I suppose it is not fully EOIO, because you don't send directly from the outbound queue to the inbound queue. The AE service may not have a specific queue for that message, until the queue is associated in adapter module. Maybe (just maybe), if you get unexpected extra processing in the initial AE reception of the message (and hence, before the queue is set, in adapter module), you may have some inconsistencies with the processing order in sender system.
But again, that is just a speculation.
I'm not sure what is the behavior it'll have.
And even if what I speculated is right, it is a really short amount of time.
But again, EOIO would not be 100% guaranteed (maybe 99% hehe).
But sometimes (most of the times) that is not enough.
Regards,
Henrique.

Advantages and disadvantages of ABAP Proxy vs. RFC call on XI target..

Hi guys!
We have a scenarion, when we send a message to XI and need to write data to SAP as the target system.
Do you have experience, what would be better? RFC adapter or ABAP Proxy? And why?
Thanx for answer!
Peter

hi,
ABAP proxy if you can:
1. /people/michal.krawczyk2/blog/2006/04/19/xi-rfc-or-abap-proxy-abap-proxies-with-attachments
2. error handling with proxies is better
3. RFC adapter (sender) is sometimes causing problems

ABAP Proxy or IDOC Adapter?

Hi all,
In my project, we are using 3 system(SAP R/3(ECC 6.0), Oracle and VAN). Data has to synchronize between these systems.
1. Oracle ->PI ->SAP R/3
Oracle system is sending Material master data to SAP R/3 ECC 6.0. At sender side I am using JDBC Adapter but at receiver side shall i go for IDOC Adpter or ABAP proxy? If I go for ABAP server proxy I need to create message type for material master in IR and then I have to write code in abap to insert MM data into tables in R/3. Please suggest which one will be better IDOC adpter or ABAP Proxy?
2.VAN->PI->SAP R/3
VAN is sending Invoice data to SAP R/3. At sender side I am using Seeburger Adapter. At receiver shall i go for IDOC Adpter or ABAP proxy?
3.SAP->PI->VAN
Sap is sending PO data to VAN. At sender side Shall i go for IDoc Adapter or ABAP proxy?
Please suggest me which one is better in all the scenarios.
How to decide which is better for the above scenarios?
Thanks In advance
Venkatesh

File to custom IDOC or File to abap proxy

Hi there,
I would like to know best approach for the following scenario.
1) i have file coming from legacy system
2) On target side SAP , I have BAPI's available (Create, Save, Commit )(No standard IDOC available)
I can create Custom IDOC and call those BAPI's in Custom Function Module
or
I can use ABAP proxy and call BAPI's
What is the best way of doing this? and Is there any other way?
Thanks
Kumar

hi,
Abap Proxy is better than RFC in terms of performance.
proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.
In your case , if there want to crate idoc from scratch level then we go for proxy and proxy support large volume of data (more than 5 mb).
One more reason is RFC , the data is converted between RFC and XML in RFC adapter. In proxy XI communicates with the R/3 in native XI language (SOAP XML).

ABAP PROXY CONNECTION TO SAP/XI

Hi,
I have the following scenery: Abap Proxy -> XI->RFC.
This abap proxy is installed in the enviroment R/3 in the client 041 and client 210.
In the client 041 it is executed with success. In the customer 210 when I execute the program abap a login screen appears in SAP/XI. Typing the login works.
The subject is: why in the enviroment cliente 210 does the login screen appear when I execute the program abap and in the client 041 not?
I enter in the sxmb_moni and appears the following in the client 210
<? xml version = "1.0" encoding = "UTF-8" standalone = "yes"?>
- 
- <SAP:ErrorHeader xmlns:SAP = "http://sap.com/exchange/MessageFormat">
<SAP:Context />
<SAP:Code p1 = "401" p2 = "Unauthorized" p3 = "" p4 = ""> HTTP.HTTP_STATUS_CODE_NEQ_OK </ SAP:Code>
<SAP:Text language = "EN">HTTP status code 401: Unauthorized </ SAP:Text>
</ SAP:ErrorHeader>

Hi Sergio,
When you execute the program abap a login screen appears in SAP/XI. Typing the login works. But It gives error
HTTP status code 401: Unauthorized
Because it is using your userID and trying to execute it,
But it is not having enough authorization.
Go and check the entry for Integration server in
Go to SXMB_ADM
Go to Integration engine Configuration
Check the Integration server Entry -
It must be
http://server:port/sap/xi/engine?type=entry
The solution is make a RFC destination of type HTTP for XI Integration server
with Target host - host
service - http port (like 8000)
Path prefix - /sap/xi/engine/?type=entry
And in the logon/security Tab, enter the user name and password for user XIAPPLUSER,
And again Go to SXMB_ADM
Go to Integration engine Configuration
Check the Integration server Entry -
change it to
dest://<RFCDESTNAME that you have created>
This way it will not ask for login and XIAPPLUSER will
have enough permission to execute it.

Vijay

PI to ECC via ABAP Proxy - Outbound Queue for HTTP

Dear Experts,
Is there any Outbound Queue for HTTP?
I've a interface scenario where the receiver is SAP ECC and the receiver adapter XI ABAP proxy. As I see in the communication channel the transport protocol used is HTTP. So I think could there be an outbound queue to manage HTTP connection when PI send the data to SAP ECC?
Just like when we are sending IDocs to ECC via tRFC, we could check if the IDoc has really been sent to ECC by checking in tcode SM58 (Outbound tRFC).
In case for ABAP Proxy via HTTP, is there any similar connection to SM58 (IDoc via tRFC)?
Thank you,
Suwandi C.

Hi Kandasami,
Thank you for the reply. I will check for it.
Hi Jens,
Yes, I mean somewhere after the SXMB_MONI in PI and before SXMB_MONI in ECC, is there any queue in between those two?
Thank you,
Suwandi C.

Call ABAP-Proxy with SOAP adapter?

Hi all,
for a PI7.1-scenario I would like to use the Lookup-API in mapping. As I know I can use either RFC or SOAP channels, however I would rather call an ABAP-Proxy in my backend system instead.
So my question is: Is it technically possible to use the SOAP-adapter to call an ABAP-Proxy?
Your help would be appreciated, best regards
David

Hi Stefan,
Interesting answer here and one that has got me curious. Hope you can help.
1. When you say it is going to be possible to call a ABAP proxy using a UDF in the mapping of XI ( Lookup ), would it be using the WS Adapter of PI 7.1?
2. If 1 is yes, is there a new API code to do this, or is it the same lookup code as used previously in XI 3.0 and PI 7.0 Days?
3. If 1 is no, can you explain maybe a little more on how this would be possible using the standard SOAP adapter of XI?
Thanks a bunch.
Regards
Bhavesh

ABAP Proxy, WEB SERVICE and RFC

Hi
I have to pull the data from XI.
I have the PDFdocument of how to integrate XI with BI.
But i am not clear what is abap proxy and web service.
Could anyone let me know basic of what is abap proxy and webservice.
Is abap proxy and webservice are present in both the systems XI&BI ?
REgards
annie

Hi,
ABAP proxy is a connection between SAP XI & BI . For all the connections need to chk in SM59, and SICF .
proxies are a replacemet for adapters whereas webservices(WSDL) are replacements for data typesYou generate proxies from an interface description in WSDL (Web Service Description Language) by using ABAP proxy generation.

The SOAP adapter enables you to exchange SOAP messages between remote clients or Web service servers and the Integration Server. Also you can use the axis framework with SOAP adapter. Check this help:
