Advantages of ABAP Proxy ?

Hi Folks,
Can you suggest me , apart from ALE/IDOC and XI interface - what are the procedure to transfer data from sap to non sap and sap to sap? I heared about ABAP proxy. Can you provide some schenario based on ABAP proxy?
Thanks in advance..!

ABAP Proxy is one type of communication with XI/PI when IDoc communication is not possible and want forward the some specfic data from R3 to non-sap Via XI.
Regds,

Wheh to use abap proxy and when to use idoc

Hi All,
Please provide some clarifications for the below points :
What is Sproxy?
2.     Why we are using Sproxy instead of Idocs
3.   When we are going Proxy ?
4.   What are the types of proxy ?
5.   How to Create to Proxy ?
6.   What the Difference between SProxy and Idocs
   7.   What is SOAP file? When we are using SOAP file ?
Thank you.

Bharat

Hi Bharat,
You seem to have a range of Questions. I will try and answer as many as possible.
What is Sproxy?
SPROXY is a transaction [T-Code] on the SAP ECC/CRM etc side where you can see the objects designed in SAP PI ESR and develop its corresponding ABAP code. SPROXY T-Code displays the Service Interface. You can read more about it in the following site:
**************** - XI - ABAP Proxy communication
2.     Why we are using Sproxy instead of Idocs
For Certain implementations Standard IDocs may not be available and it is quite tedious to create a Z- IDoC and therefore it is advantageous to use Proxy. You can read more about this doubt in the following links:
Choosing to use IDOC standard or ABAP Proxy?
IDOC vs Proxy
ABAP Proxy Vs IDOC
3. When we are going Proxy ?
When there are no Standard IDocs available. Please refer above links to get an answer for this.
4.   What are the types of proxy ?
5.   How to Create to Proxy ?
Again the following link has the answers for both these questions:
**************** - XI - ABAP Proxy communication
6.   What the Difference between SProxy and Idocs
Difference is in the way the communication happens. Standard Idocs are already provided and you can use them directly while Proxy you will require to write the code on ECC side. You can refer the following link to understand more:
Advantage of ABAP proxy over BAPI
7. What is SOAP file? When we are using SOAP file ?
I have not heard of anything called SOAP file. SOAP is a protocol used for communication and you can send files as attachment in your SOAP to Any(file/idoc/Soap etc) or vice Versa Interfaces. Infact Proxy itself is SOAP based communication with XI 3.0 Protocol.
Please explore SCN to know more about the various scenarios. There are endless possibilities in SAP PI.
Hope this Helps.

Using ABAP Proxy

I am researching a way to integrate SAP system with ABAP Proxy. I have sevareal questions.
1. Is it possible to use XI alerting for ABAP
2. Is it possible to use application acknowlendgement with asynch ABAP Proxy.
3. When I generate ABAP class in SPROXY transaction do I need to change it by hand or I can to map this proxy to RFC function or BAPI? Is it possible to generate interface in XI by BAPI or RFC and then generate ABAP Proxy?
What is the advantage of ABAP Proxy? I think it requres more ABAP coding...
I have read some blogs but I haven't got answer

Hi, Sergey.
I can try to answer questions 2 and 3. Regarding 1, unfortunately, I haven't tried yet.
2. Yes, definitely.
If you are programming a client proxy (outbound, that is sending data to XI and then to another system) you can require ack and in case the receiver system is able to produce ack (for instance inbound ABAP or Java Proxy), it will be routed back to the sender system.
If you are programming a server proxy (inbound, that is receiving data from XI), raising an exception inside ABAP code will put the R/3 message in "Application Error". The fact that this ack is routed back to XI and to the sender depends on who sent the original data to your proxy: as far as I know, just BPM is able to require ack.
3. Don't confuse RFC with Proxies. The technology behind is really different. Either you use RFC/BAPI stuff (and in this case from an XI perspective you are using RFC Adapter) or proxies (using XI Adapter).
When you generate with SPROXY you have to:
1. write your own abap code to manage data if that's an INBOUND MESSAGE INTERFACE
2. nothing if it's an OUTBOUND MESSAGE INTERFACE, except find the right point in the system where to invoke it (report, customer exit, module pool or whatever).
Finally, the great advantage of proxies is XI native protocol usage. It doesn't require more ABAP. The ABAP code is the same you would put in a function module. The difference is that with proxies you are in an ABAP Object context, which is not the case of functions.
Hope this is exhaustive for you!

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:

2. error handling with proxies is better
3. RFC adapter (sender) is sometimes causing problems

ABAP Proxy ABAP Mapping

Hi All,
The use of ABAP Proxy is nothing but the Adapterless implementation,as per my assumption.But is there any other reason for prefessing ABAP Proxy over the Adapter while the practical implenentation is done?
Also,for ABAP Mapping ,I have a qustion that when is ABAP Mapping preferred over other Mappings that is Graphical Mapping and Java Mapping while practical implementation?
Thanks and regards,
Amol

Hi Shweta,
To answer your first question, we prefer ABAP proxies over RFCs due to the reason that the communication happens directly between the Integration Engine of sender sap R/3 system and the IE of the XI system. It elimintes the need for Adapter Engine(On the sender side).
However, when there are standard IDOCs avaialble, then we use IDOCs instead of proxies due to the various other advantages of IDOCs like monitoring, reprocxesing etc.
But, in case the sender is not a SAP R/3 system, then obvious we can not use ABAP Proxy.
Refer this article to choose the best integration option amongst Proxy,RFC,Enterprise Services.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c0e7ae66-be6d-2a10-d385-92e6e67dee10
Regarding your second question,
ABAP mapping is least preferred due to issues like Performance, Non-Portability (We cannot use the abap mapping in any other Open-source middleware).
The only time we go for it is if we have people with only ABAP skills..:)

Java Proxy and ABAP Proxy

hi,
can any one send me some documents on Java Proxy and ABBAP Proxy
regards,
John

hi,
Proxies are nothing but a mechanism to shift the application logic from the XI server onto the sender or reciever system so as to reduce the effort on the side of XI.Depending upon where the proxies are generated ,it is differentiated as client proxy ( sender ) and server proxy ( receiver ) .In R3 system having WAS 6.2 and above its already has an inbuilt small IE so the proxy generation is favoured and possilbe,for more on this please go thru the following links
Proxies: are interfaces which will get executed in the application system. They can be created only in the system from message interfaces using the proxy generation functions.
The biggest advantage of the 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.
The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages. The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with.
The Proxy currently has the following components available:
1. ABAP Proxy Communication using XI or Web Services
2. Java Proxy Communication using XI (J2EE)

JDBC to Synchronous ABAP Proxy

Hello,
I have one scenario where i am sending data from JDBC Adapter(Communication Channel 1) to ABAP Proxy(Sync)(Communication Channel 2) and as response ABAP Proxy send back data to JDBC Adapter(Communication Channel 3). So is it possible without BPM?
And in above scenario in SXMB_MONI of R/3 and PI 7.1 it shows "Type = Asynchronous" and in R/3 it shows Payload in Response but when i check in PI 7.1 SXMB_MONI there is no message in Payload of 'Response' .
Please suggest me the solution.
Thanks in advance.
RP

YES , WE CAN ...
We can use JDBC Adapter at your DB Side and At R/3 side we can have RFC or Proxies for Sync
By default JDBC Adapter dont have the nature of requesting the Ack(Response from the receiver)
So to make it Sync We have to use BPM
JDBC Synchronous call using BPM
How to uses JDBC Adapter for the following scenario ?
Steps to be followed for the same:
SYNCHRONOUS SOAP TO JDBC - END TO END WALKTHROUGH
ABAP proxies have many advantages for instance; they 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). ABAP proxies supports two different protocols; XI and Web Services. Most important is that they can be used for both synchronous and asynchronous communication (RFC/BAPI is basically only intended for Synchronous comm. which asks much more system resources from your XI system).

What is a Proxy, specifically ABAP Proxy?

Hi,
Friends, I need some basics about proxy , ABAP Proxy with respect to SAP XI.
1.Why do we need a ABAP proxy?
2.For what do we use a proxy and what are the uses and applications of proxy?
3.What all do we need to create in IR and ID to work with ABAP proxy?
If we have any good blogs giving a detailed explanation of all the queries, it would be highly helpful.
Thanks in Advance.
Younus

Hi Younus,
There are two types of proxies in ABAP:
1)ABAP Client Proxy
2)ABAP Server Proxy.
ABAP Client Proxies are used to communicate the R/3 system to XI. And where as ABAP Server proxy is used to communiate the XI system to the R/3 system.
ABAP Client Proxies are created using the Outbound Message Interfaces and ABAP Server Proxies are created using the Inbound Message Interfaces in the Application system using sproxy Tcode.
These proxies will directly hit the integration engine of the XI server and thus reduces the use of adapters.
When you generate the proxies using Tcode SPROXY in ur application system then u have to:
>>> write your own abap code in the interface to manage data if that is an Inbound Message Interface.
>>> In the case of Outbound interface then write a report and invoke the appropriate method (eg:execute_asynchronous or execute_synchronous) to trigger the proxy.
The great advantage of proxies is XI native protocol usage. It doesn't require more ABAP. The ABAP code is the same you would put in a function module.
>>>What all do we need to create in IR and ID to work with ABAP proxy?
If u r defining the Client abap proxy then no need of sender communication channel and sender agreement.
While in the case of Server abap proxy u need an XI adapter in the receiver communication channel to communicate with the R/3 system.
The use of adapter here is to communicate the IS with respective to the application s/y.
Remaining all the stuff is same as the normal scenario.

ABAP Proxy Vs IDOC

What are all the advantages ABAP Proxy has over an IDOC?
When to go for an ABAP Proxy?

Pete,
Proxy and Idoc:
IDOC : After recieving the strucutred data It processes it using a Function Module associated with it. If you have a standard Idoc for your requirement then you should go with Idoc only.
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.

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
dennis

Ogawa,
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.

RFC VS Abap Proxy

Quest point where the RFC is better the AbapPorxy than?
In me to inform

Hi ChangSoo
1. The biggest advantage of the 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.
2. 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.
3. ABAP proxies supports two different protocols; XI and Web Services
4. Most important is that they can be used for both synchronous and asynchronous communication .
RFC/BAPI is basically only intended for Synchronous comm. which asks much more system resources from your XI system.
5. Proxies are used when you have large chunks of data coming in and that too if its unstructured, so if it comes from a SAP system we go for a ABAP proxy, if its from a non sap system, we take a java proxy.
For abap proxy we may use a report to send a proxy data to sap xi.
6. EOIO quality of service can be obtained with Proxies and not with RFC/BAPI.
RFC/BAPI support BE( Best Effort ) when used synchronously.
Cheers...

Choice Between IDOC and ABAP Proxy

Hello All,
We are building a Bi Directional Interface for Business partners between a third Party ERP, XI and SAP CRM.
We are looking for some advise on the best way to go forward between the two options below:
a) Do an ABAP Proxy Call on Fn Module CRMXIF_PARTNER_SAVE from XI
b) Create and IDOC in CRM
( Message Type CRMXIF_PARTNER_SAVE_M )
Not being an XI consultant, my understanding is as follows
Option A : Gives me the flexibility to format my response in the manner we like. But this is a synchronous call. Also this is a generated RFC. So changes in the XIF layer of CRM could be an issue.
Option B : Response can be achieved only through the ALE Audit Functionality, which has a predefined message structure. For Eg: If I wanted to send the response in the same format as the incoming message with an added segment for the error, this is not possible. Ofcourse, I get all the functionalities of monitoring and Handling IDOCs in this option.
Any thoughts on the advantages and disadvantages of each option would be greatly appreciated.
Thanks
Anoop

Anoop,
I probably should have mentioned in the BLOG, that IDOC is good if its a standard IDOC, so that you don't have under go the pain doing the modifications for the custom one.
In your case, PROXY might make more sense as you are saying that you have to do some custom processing as well. So, you can call the BAPI / Function for the standard processing and then do the custom processing in your Proxy code. And more over, if you have want to have a Synch interface, then you cannot use IDOC.
So, the options in this case boil down to PROXY / RFC.
PROXY will definitely have the advantage as its going to bypass the adapter engine and directly interact with the Integration server. And moreover, even if you already have a RFC, you can always call that inside your PROXY. However, the only flip side here compared to IDOC, is that you will have to create all your IR objects manually.
Hope this helps you in making your decision.
regards,
Ravi

Error while activating ABAP proxy object

Hello,
I can see all the interfaces of PI7.0 in my ECC6.0 system.
I am able to create abap proxy object of a interface.
But when I try to activate that I am getting error as
"RFC system error for destination GTADIR_SERVER".
Pl can you suggest. appreciate quick help in this.
thanks in advance,
Sharada

Hi,
For more details take a look at note: [1063482 - Creating Dictionary objects - RFC error GTADIR_SERVER|https://service.sap.com/sap/support/notes/1063482]
It is written that: Message SGSUB 104 is not an error message, but is merely irrelevant information for customers. You can continue to create objects nevertheless.
To get rid of this annoying error you have to implement the corresponding support package.

Jakub

Activate abap proxy withou java stack on ECC side

Hi gurus,
Can we activate abap proxy on ECC side if the ECC don't hava java stack? As you know , we need to create two jco RFC provider in Visual Administrator, but without installing java stack, we can't do that. Any ideas? Thanks in advance.

Thanks all.
Solved by using program id of XI system in the RFC of application system.
But we still face the issue in SPROXY. It gave the error "No connection to Integration Builder ".
Then I runned connection test, and found SPROX_CHECK_IFR_ADDRESS and SPROX_CHECK_HTTP_COMMUNICATION
are right, but SPROX_CHECK_IFR_RESPONSE and SPROX_CHECK_IFR_CONNECTION are giving the error "Integration Builder data not understood". Any ideas?
