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 ?

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:

What is package structure for Client ABAP Proxy?

1. What is the package structure need to be followed for creating abap client proxy.
2. I read some where in the form, it need to be 4 levels. Why is it?
Thank you
Ganges Leaves

Hi
U hav to create a 4 level package structure for client ABAP proxy.
U can create ur on packages
1st level-structure package.
2nd level-main package.
3rd and 4th level-sub packages.
To the 4th level only u hav to create proxy.
The classes and code wil be automatically generated at the time of proxy creation.
I think the 4 level structure bcz while in r/3 everythin in integration builder like software component version and all wil be takin as different levels.
Also u can go through the weblogs in the above replies u got.

What is ABAP/JAVA Proxy and whats the use of it?

Hello All,
What is ABAP/JAVA Proxy. And why do we need to use them? I am not sure of the definitions given on help.sap.com. Thats the reason I am posting this question. Right answer will be rewarded. Thanks in advance.

Farooq.

HI Farooq
ABAP Proxy
ABAP server proxy is created for the inbound interface creted in XI's Integration repository proxy should be created in the business system for which the interface is created .
U can reference following link :
http://help.sap.com/saphelp_nw2004s/helpdata/en/02/265c3cf311070ae10000000a114084/frameset.htm
Server Proxies are generated for Inbound Message Interfaces. These are used to Process the Data coming into SAP System from an external application.
Sproxy is the transaction to generate Proxies.

Java Proxy
Java Proxoies are used to allows your java Applications ( j2ee, j2se applications )to interact directly to the Integration Server of XI without any special adapters.
All documents are available on SDN itself .

Proxies help you achieve non-standard functionality for which the out of box XI adapters do not suffice. Just to give you an example, consider a system with which XI has to integrate , the only interface the system offers is a TCP / IP socket based interface. You could write a Java proxy which would interact over sockets with your target system, which is not possible with other standard adapters which are shipped with your XI installation
You can refer demo on SDN TV, on this link

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.

SAP PI 7.4 SOAP - ABAP Proxy Synchronous Webservice

Hi Everyone,
I am developing the following scenario:
3rd party makes a SOAP call to SAP (via PI) to determine whether a vendor exists or not in the SAP system. The link for the call is provided by us from the Integrated Configuration.
The request comes in, calls an ABAP Proxy to check if a vendor exists and sends a response back to the SOAP call with a 'Y' or an 'N'.
I've read a lot about various scenarios but I'm having trouble connecting the dots as I'm fairly new to PI. I'd appreciate any help.
I've made the following set-up based on assuming I need separate Service Interfaces for the SOAP Request & Proxy Response
ESR
1. Message Types
     SOAP (MT_SOAP_REQ & MT_SOAP_RESP) - PROXY (MT_PRXY_REQ & MT_PRXY_REQ)
2. Message Mappings
     MM_REQUEST    which maps MT_SOAP_REQ   to MT_PRXY_REQ)
     MM_RESPONSE which maps MT_PRXY_RESP   to MT_SOAP_RESP)
3. Service Interfaces (Synchronous)
    (SOAP Request)
    SI_IN (Inbound Interface)       with Request = MT_SOAP_REQ and Response = MT_SOAP_RESP
   (Proxy Response)
    SI_OUT (Outbound Interface) with Request = MT_PRXY_REQ and Response = MT_PRXY_RESP
4. Operation Mapping
    OM_LOOKUP which maps SI_IN to SI_OUT with Request    (MT_SOAP_REQ to MT_PRXY_REQ)
                                                                    and Response (MT_SOAP_RESP to MT_PRXY_RESP)
I create the ABAP Proxies for each Service Interface. SI_IN contains the required coded method to check if there is a vendor.
I create the webservice and binding for SI_IN in SOAMANAGER
At this point I'm somewhat unsure - what do I need to do for SI_OUT ? Do I need to create a logical port ? how is SI_OUT associated to SI_IN (apart from the Operation) to get the response.
ID
In the Integration Directory I've created a SOAP_SENDER communication channel for System A and SOAP_RECEIVER channel for SAP. For the SOAP Receiver I need to specify a URL - what should this be ? Is it meant to point to the web service for SI_IN in SICF or just to the generic http://host:8000/sap/xi/engine?type=entry
Do I need to use the HTTP_AAE adapter for the receiver instead of SOAP ?
I created an Integrated Configuration for the SI_IN Service Interface with comm channel SOAP_SENDER from System A and SOAP_RECEIVER for SAP backend. I then got the WSDL for this to provide to the 3rd Party to test (via SOAP UI) . Again my concern is how is the SI_IN linked to the SI_OUT to achieve the response ?
I appreciate you taking the time to go through this . Any help is greatly appreciated.
Thanks very much
Gary

Problem with Configuration in Production ( ABAP Proxy - XI - FILE)

Hi All,
I have a ABAP Proxy -> XI -> FILE scenario wich is working perfectly in DEV and QAS environment.
When the person responsible for transporting tried to transport the objects in QAS to PRD, the following error happened:
Direction of communication channel |BS_MA_FileServer_PRD | CC_File_PedidosServ_MA_FileServer_IA is incorrect.
Correct the direction or choose another communication channel
BS_MA_FileServer_PRD - Business System (FILE)
CC_File_PedidosServ_MA_FileServer_IA - My FILE Communication Channel
This was what the Basis person sent to me. I don't have access to know exactly what happened. And I really don't know what could be wrong or if maybe a component was created wrongly in Production.
Hope you can help.
Points will be given.
tks.. Daniela

You have mentioned FILE is on the receiving side and ABAP proxy is on sender side.
But the error pasted by you clearly shows syntax of a Sender Agreement .
For receiver agreement it should be |<Sender Service>| |BS_MA_FileServer_PRD | CC_File_PedidosServ_MA_FileServer_IA

Error while executing sender ABAP proxy program in ECC

Hi,
We have lot of proxy to file scenarios, most of them are working fine. I am having issue with 2 interfaces, when I execute sender ABAP proxy program, we are getting following errors in ECC:
<SAP:Category>XIProtocol</SAP:Category>
<SAP:Code area="PARSING">GENERAL</SAP:Code>

Configuration should be fine because many scenarios are working. Can you please help me where could be the error?
Let me know if you need more info.
Regards,
N@v!n

Hi Naveen,
We saw your solution about this issue. We are also facing same issue. I wanted to know where we have to update scenario as simple scenario or integrated scenario.
And could you please tel me what is the main diff between in these two.
As we are are using PI 7.31 java stack so for this version what we have to use.
Thanks,

ABAP proxy exception to SOAP fault and vice versa not getting mapped

Hi there,
I have these scenario's: ABAP proxy to SOAP (AXIS framework) and the other way around, synchronous, using AAE.
When declaring the Synchronous Service interfaces we also defined error message types in order to pass system and application exceptions back to the service consumers.
The behavior we are observing is as follows;
When an exception is generated on the ABAP proxy, the error message type is correct generated and filled with the corresponding values in the ABAP proxy runtime. However, when the response arrives at the service consumer, it only contains a SOAP fault filled with some kind of generic PI mapping exception information.
1. Why is the original ABAP proxy exception not mapped/passed into the SOAP response?
2. What can we do in order to change that situation?
3. Does it has to do with the use of the AAE - Advanced Adapter Engine or the AXIS framework?
PS: We have performed a test of the Operation Mapping - OM using the ABAP exception as input and it did work correctly, so the error structure seems to be Ok.
Many thanks for your replies.

Problem was caused by some differences in namespaces between source and target.

XSD Data Type to ABAP Proxy Tech. Type

I am working with an ABAP development team who is creating PROXYs from the Service Interfaces I have setup in the ESR (PI 7.11). I have been asked to set the type of a numeric field by the ABAP developer as this:
"Yeah we can convert from string to currency but sap internally stores currency with 3 decimals so we may got to do some multiplications and divisions based on how many decimals sender passes. If you could create a numeric with 3 decimals that is ideal."
The XSD type as xsd:decimal, but in the proxy it seems to create Tech. Type = STRING.
I can apply formatting rules in the message mapping, but developer is convinced that the Service Interface can have the correct ABAP Tech. Type. I do not find any messages in this forum, so not sure what to do.
Thank you for your time.

Internal ABAP types like packed or float cannot be created by ABAP proxy.
I recommend to use String for any type. Inside XML you will have a String representation anyway, but you will encounter less issues in converting from XML to ABAP internal types.
I work a lot with currency fields, it is no problem at all. Inside ABAP you mave currency field to string field, the decimals are correct.
If course, in mapping you have to create a decimal field, but this would not be any change, if you had a decimal type in ABAP.

Business partner replication using ABAP proxy

Hello,
I want to send vendor master data records from the MDM to SAP SRM. There is a standard ABAP proxy interface in the SRM for this purpose and this proxy is also being used by the standard PI content for MDM.
Do you have any experience with this interface? I have done some test cases and I missed the logging. In PI I don't get any feedback if the business partner has been created or not. And in case it was not, there is no detailed error description. Neither in SXMB_MONI in the PI nor in the SXMB_MONI in the SRM.
Is there any other monitoring tool for this interface?
Would you recommend to use this interface in production, or would you prefer to use the BAPI interface?
Any comment appreciated.
BR,
Jürgen

Hi Jürgen,
yes I worked on a similar scenario, we were distributing customers to CRM, which is the dual of vendors in SRM, and at the end is just a different role of the business partner.
The Proxy I used is the standard proxy ABABusinessPartner, which is part of the standard content, and we never had problem using this object (productive since more than a year).
What is strange to me is that you do not see any trace in SXMB_MONI, you should see the message in both XI and SRM and when a message is in error you should see the trace there with a description of the issue.
Regarding Acknowledgement I think you have to configure MDM to request an acknowledgement since the ack only comes back if the first sender of the message request it.
Hope this help.
Ciao,
Sergio

Message flow in SAP PI 7.31 JAVA only for ABAP Proxy synchronous scenario with Oracle DB

Dear Experts,
I am working on a synchronous scenario Sender ABAP Proxy <===> SAP PI 7.31 JAVA only <===> Oracle Database.I have successfully
configured all the proxy configurations as well both Sender SOAP and JDBC receiver channels are showing no error when pinged from
Cc monitoring in NWA.
1.During testing at Tx SPROXY , I am triggering a message and after 5 minutes I receive an PARSING error message with 2 messages in ECC
local IE i.e. Tx SXMB_MONI.
Note : In NWA , I can see only 1 message that too in cancelled status.
2.Seeing the trace of the messages I assume that the messages have not moved from sender ECC system. I am still confused with flow of message
from the Message Audit log. Audit log of error messages.Could any one share the full Audit log of a successful message generated in SAP PI 7.31 JAVA only.
3.I observed that the QIN Scheduler status in ECC is in INACTIVE status. There is no queue id for 2 messages generated in ECC. Does
it should in ACTIVE status in Tx SMQR..
Regards
Rebecca

Hi Thomas,
Valuable inputs..
1. Since I don't have any audit log for successful message, would you be able to share referring to the
below screenshot whether the message was put into receiver JDBC adapter and JDBC adapter tried to retrieve the Select response from Oracle Database.
2.I have done some setting in Advance mode of the receiver JDBC to increase the time out and other parameters as per SAP note but still the issue is same. If you perhaps have some experience in such scenarios, please share some input so that I can ask the Oracle Database administrator exactly what is required from our side.
3.Regarding the slow response from Oracle , there was some suggestion that the datatype of the request and response should match the column name of the Oracle database. I did that.. Do you have any more suggestion that may be hampering the generation of the response message from the Oracle like SAP note or document.
Regards
Rebecca

Problem Mapping to ABAP Proxy

Hello,
I Have a very strange error.
So i send a Message from Java Proxy ->to-> ABAP Proxy.
The Mapping is a XSLT Mapping.
The Mapping everthings fine but the ABAP Proxy get and error like:
Error during XML => ABAP conversion (; error ID: ; ( ))
....CREATE_TRANSACTIONS(1)IT_TRANSACTION(1)item(1)OPERATORQUAL(9) Error Text: Data loss occurred when converting 9134408 Kernel ErrorId: CONVT_DATA_LOSS))
Ok the error is normally not so strange, but in my XML Message the tag OPERATORQUAL is empty. The 9134408 ist the last filled tag for the OPERATORQUAL.
Why the ABAP Proxy think there is something in ?
I checked the XML and there is nothing.
But when the proxy think there is something like 9134408 that the error is normal, because the field has only except only 1 Char Values.
Any Idea whats going wrong?
Regards,
Robin

Hi Udo whats up ? ,
Mappings all works fine.
Problem was that blanks was there in the XML Tag that you can't see in the XML view.
This blanks came already from Database.
Know i kill all blanks in XSLT Mapping and it Works !
see you soon and regard from zagreb,
Robin

How to use CL_PROXY_BASIS instead of CL_PROXY_CLIENT your ABAP Proxy class?

Hello experts,
I have a scenario where a new basis release was done in my development and testing SAP boxes (Basis Release 710 I believe) which means from then on when generating an ABAP Proxy class the inheriting class will be used is CL_PROXY_CLIENT as opposed to the previous CL_PROXY_BASIS.
This causes a problem though because the target date for the project, which uses this ABAP proxy, is supposed to be in the production system before the date when the basis release will be done in the production system. Obviously this will cause delays in my project since if I were to move my objects to production before the basis release a dump/syntax error will occur in production because the class CL_PROXY_CLIENT is not expected be production yet.
The next plan is to try to use CL_PROXY_BASIS instead of CL_PROXY_CLIENT, by editing my ABAP Proxy Class be force. My question is, what steps do I need to take so that I can change these classes so CL_PROXY_BASIS will be referenced/used instead of CL_PROXY_CLIENT ?
I hope to hear from all of you soon.
Regards
