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..:)

Coding for ABAP Proxy and mapping

Hi XI Ds
which one need coding neither ABAP Proxy nor ABAP Mapping
Thanks

Hi Kushee ,
We need coding for both ABAP Proxy and mapping. We need to know some OO(Object Oreinted) ABAP concepts.
We can also import JAVA CODE for certain functionality.
Check the following websites for clarity:

Performance problem in File to ABAP Proxy scenario

Hi gurus,
 I have a scenario where the sender is sending a file and the receiver is ABAP Proxy.The file is a simple DAT file containing banking data.The file sample is as belo

7042010210000020192D
The above file need to be split and mapped to the fields of the ABAP Proxy after doing some validations.
Is Receiver Determination using mapping required? What is the most efficient way of splitting the file?
Please give your replies keeping better performance of the interface in mind.What is the best way of doing the validations?
regards
Debansu

Hi Satish,
 As you can see in my question above,the sender side contains a flat file(the file format is given in the question),I need to split the file into strings which can then be mapped to specific fields of the ABAP Proxy.A sample output of the xml file that is passed on to the ABAP proxy after mapping transformations is given below:
<BATCH_TOTAL_RECORD_420>
<BATCH_REPORT_DISTRICT>70</BATCH_REPORT_DISTRICT>
<KEY_VALUE>420</KEY_VALUE>
<BATCH_NUMBER>1021</BATCH_NUMBER>
<BATCH_TOTAL>0000020192</BATCH_TOTAL>
<FILLER_BATCH_TOTAL_SIGN>D</FILLER_BATCH_TOTAL_SIGN>
<FILLER />
</BATCH_TOTAL_RECORD_420>
- <BATCH_TOTAL_RECORD_420>
<BATCH_REPORT_DISTRICT>70</BATCH_REPORT_DISTRICT>
<KEY_VALUE>420</KEY_VALUE>
<BATCH_NUMBER>9999</BATCH_NUMBER>
<BATCH_TOTAL>0000202366</BATCH_TOTAL>
<FILLER_BATCH_TOTAL_SIGN>D</FILLER_BATCH_TOTAL_SIGN>
<FILLER />
</BATCH_TOTAL_RECORD_420>
I hope now you can provide me some answers.

File/FTP to ABAP Proxy (file as attachment)

I have the following scenario: File/FTP -> XI -> ABAP Proxy but not the normal case. What I need is the picked file as attachment and the file name. I hope this is possible.
I have found the following blogs:

I have no idea where I have to start. How I should define the sender and receiver message interface? How I have to configure the sender file/ftp adapter?
I'm using PI 7.1 SP 7.

At the moment I have the following problem. I always get an error during mapping the request message. This is the error message:

ABAP proxy related issue

Hi All,
Good morning,
i working with ABAP proxy to file scenario. the requirement for this scenario is we are fetching data from data base to internal table then using that table we have to write code and send data to xi. can give me past response that how to write code using internal table. i want only code related internal table not total code.
thanks for fast response.
regards
sai

Hi Sai komala,
After genrating the Proxy, you can view the calss & structures genrated by proxy.You need to create an object with refrence of Class and to be create workareas for your Message type and Data type strucutres. Create an Internal table with your desired structure and do the validations as per your mapping rules.After completion of your all validations you need to populate your final internal table data to the structure of message type and call the execute asynchronous method.
Have a look into following weblogs

TO debug u r proxy code, just like your normal R3 report program. put a breakpoint and execute the program , you can view the debugging of your proxy.
Hope it will helps to solve u r probolem

ABAP Proxy Structure

Hi,
I have SAP server at sender side, XI is my middleware and two 3rd partyservers on the receiver side.
So,from SAP side data comes through proxy,I would generate a structure which contains the fields required to send the data to both the receivers.But few fields would used to send the data to one server and some fields to another server.
So, once the data is filled,there would be a segreation process internally writeen in proxy to segregate the data.
So, Now can i use the same structure for all the proxies i generate to send the data or should I generate different structures for each and every interface.
Thank you,
Kishore J.

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

How to configure systems for ABAP Proxy use

Can somebody please point me to the documentation regarding the configuration settings for the use of ABAP proxies, on both the XI and client sides? I have performed readiness checks as specified by SAP, the ABAP Proxy tests all pass, yet when I write a program with a proxy, the message does not appear in the integration engine monitor.
I think I have missed something in configuration settings, but don't know for sure. hence the request.
Kind Regards,
Tony.

How do ABAP Proxy and XI adapter work?

Hi everybody,
I have a general question about the ABAP proxy and XI adapter.
In order to use the ABAP proxy and XI adapter, I must configure the HTTP Destination between the R/3 system and the XI server. I must also maintain the SLD.
After several hours configurations with our administrator, it failed. At least the HTTP Destinations on both servers don't work correctly. We got always HTTP error message. But a scenario with an ABAP Receiver proxy works! It is really strange and laughable. We're very happy about that but don't know why and what happened. Today we tested the ABAP Sender proxy, it doesn't work.
So we decide to ask the XI experts in this forum to give us a general lessen about the ABAP proxy: how it works, why we should create the HTTP destinations, how do the destinations work and so on.
Thanks a lot in advance!
With best regards
Xiang

Hi
Once you create the interface in XI, you generate the proxies on your R3 system.
Client Proxies -->
This is done for outbound interfaces. You generate the proxy and then write a report that fills in the proxy class with the data and pushes it to XI.
Server proxies -->
Generated for inbound interfaces. Generate the proxy and write the implementation for the exectue method that deals with the data sent from XI to the R3 system

we create http destiantio because in proxies , adapter is not use so who is goin to send the message to integration server ...by creating http destinatio we create integration engine which send messg to IS . then messg is routed .and all
error in HTTP to file scenario http to file
hope this help's you

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)

ABAP Proxy Attachment

Hi All,
I had created an ABAP proxy which sends an XML message along with an attachment(PDF). The PDF is written to the application server first (just to double check the correctness of the file) and then the same file is sent to the XI as an attachment. But when i download it from the SXMB_MONI to the local system, it is saying that the file may be corrupted or might be a poblem with the decoding. i had gone through the following weblog.
[/people/michal.krawczyk2/blog/2006/04/19/xi-rfc-or-abap-proxy-abap-proxies-with-attachments|/people/michal.krawczyk2/blog/2006/04/19/xi-rfc-or-abap-proxy-abap-proxies-with-attachments]
I'm using the following code to send the pdf as attachment.
attachment_protocol TYPE REF TO if_wsprotocol_attachments,
      attachment          TYPE REF TO if_ai_attachment,
      attachments         TYPE prx_attach,
      attach_xstring      TYPE xstring.
attachment_protocol ?= prxy->get_protocol( if_wsprotocol=>attachments ).
      attachment = attachment_protocol->get_attachment_from_binary( data = attach_xstring
            type = if_ai_attachment=>c_mimetype_pdf
            name = 'Invoice_attachment' ).
      APPEND attachment TO attachments.
      attachment_protocol->set_attachments( attachments ).
Can anyone please help me out in resolving the issue.
Thnx in Advance
Anil

Hi Anil,
I have the same scenario .I need to create the PDF attachment in ABAP client proxy for Invoice document.Do you have any idea or sample code to attach the PDF document.
And is there any special steps i need to follow in the ESR in the atachment point of view.

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.
