File - ABAP Server Proxy - Error - CL_MAPPING_XMS_PLSRV3-ENTER_PLSRV

Hi,
I am working on File-ABAP Proxy(Server) scenario. I've created the repository and integration objects correctly and have activated them. When I do a Test Configuration in the Integration Directory, I am getting the below error:

The above error says that the error is: "Mapping already defined in interface determination". But I've double checked my Interface Determination, it is correct.
And if I try to post the payload in the Integration Engine in RWB, I see the status as "Recorded for Outbound Processing" in SXMB_MONI. If I try to release the queue, the status is "SYSFAIL".
For your information, I'm working on SAP PI version 7.11 PI 7.1 EHP1 SPS 03.
Any inputs on this eror will be really helpful.
Thanks,
Vijay

Hi Vijaya,
-->Try to execute the end to end scenario with out testing it in the Integration Directory(ID).

ABAP Server Proxy OR RFC - for attaching a file

Hello ABAP gurus,
Just to give a brief background, systems involved are ERP and PI
Certain Files (3 files to be exact) are generated in the ERP directory/file system
I need to transfer these files to PI "without" using the readily available FTP/NFS adapters (this is a limitation - no use of direct FTP is allowed)
Making the directory as a "shared" directory between ERP and PI is also not an option.
With the scenario above, I though of using an RFC or an ABAP Server Proxy to attach the said files to send them to PI
Which is the better way to do it?
I've seen a documentation for the ABAP Server Proxy that makes it possible to attach files to the proxy message, but for RFC I don't know if this is possible?
Your expert advise is highly appreciated

hI,
Use class CL_PROXY_CLIENT in the program and method IF_PROXY_CLIENT~EXECUTE.
You can refer documentation of this class as well as if you will search on any search portal using name of this class, you will get the briefe idea with the refernce procedure too.
Unfortunately I am unable to post you few links but try search on it, hopefully you will get it.
try below link.

File to ABAP Server Proxy Scenario

Hi 2 all,
I am running File to Server(ABAP) Proxy scenario...
I have checked the ABAP Server Proxy at application server only and it is working fine....But when i am running the whole scenario my server proxy is not getting executed..( i.e my file is being picked up but proxy is not getting called ..:(( )
Can i expect some valuable inputs regarding this issue..?
Regards,

to debug the problem....
first check SXMB_MONI of R3 system... where proxy has been created.
1 .check whether your proxy has been called ... it will be evident you get any message in moni for you interface or namespace..
2. check you proxy message has not got stucked in queue... sometimes message get stucked in queue and hence proxy are not called.. release the messaeg using smq2.
ELSE
1 .go to SXMB_MONI...of XI..
2. select 'Call Adapter' in right hand of monitor.
3. check the 'trace' under Call Adapter.
4. if you go at end of trace or somewhat near to end.. there should trace like...this ...
Trace level="1" type="T">Receiver party normalized =</Trace>
<Trace level="1" type="T">Receiver party external =</Trace>
- <Trace level="1" type="B" name="CL_XMS_PLSRV_CALL_XMB-CALL_XMS_HTTP">

<Trace level="3" type="T">Deserializing message object...</Trace>
<Trace level="3" type="T">HTTP-client: closing...</Trace>
</Trace>
check whether connection establishment between XI and R3 is successful or not...
if you are getting same message as above ,,that means ur RFC is working fine...
problem is on r3 side.. for this go to r3 and check moni...

Problem with Consuming ABAP Server Proxy WSDL in InfoPath

Tried to design a InfoPath (MS Office 2003) form from a WSDL file of a web service generated from an ABAP Server Proxy in a NW2004s SP10 system. InfoPath rejected this WSDL with error InfoPath cannot use the selected Web service method for receiving data because the method does not provide valid XML data. Tried other WSDL files from other web services from ABAP Proxy with InfoPath, all got rejected.
Validated the WSDL file with XMLSPY, no error. Tried to import the WSDL into XI 3.0, no error. Also tried the WSDL in .NET C#, also worked fine. It seemed only InfoPath does not like this WSDL from ABAP Proxy.
Created a similar web service in XI 3.0 and InfoPath had no problem with its WSDL. Then I compared the two WSDL files. There are differences. After try and error on changing the differences, I have nailed down to the XML tag that caused the problem. Please see the extracted WSDL line attached at the end. In the XI 3.0 generated WSDL the wsdl:message and the wsdl:part have the same name. In the ABAP Proxy generated WSDL the wsdl:part has the name Parameters which is different from the wsdl:message. After I copied the wsdl:message name to the wsdl:part name, InfoPath accepted the WSDL file without any problem.
I know the fix but I like to find out the root cause. Is this a known issue? Did we miss some configuration setting thats causing this issue? Any help will be much appreciated.
WSDL from NW2004s SP10 ABAP Proxy
<wsdl:message name="RegionR3GetList_Req_MT">
 <wsdl:part name="Parameters" element="tns:RegionR3GetList_Req_MT"/>
</wsdl:message>
<wsdl:message name="RegionR3GetList_Resp_MT">

</wsdl:message>

Anne Tarnoruder has pointed out to me that her SDN article "Consuming SAP Enterprise Services in a Microsoft Office InfoPath Form" has described the the cause and workaround of this issue on page 9. I am extracting it below and mark this thread as answered. Thanks to Anne but not sure how I can award point to her.
Currently SAP supports only the Document style of WSDL, and not the Microsoft-specific RPC style, which causes a problem when consuming SAP services in the Microsoft environment. In this example, you need to apply a workaround that involves a minor correction of locally-stored WSDL files:
a. In the Project Explorer toolbar, click the Show all files icon and expand the Web reference folder.
b. For each Web reference in the project, perform the following steps:
c. Open the WSDL file, replace all instances of <wsdl:part name="parameters" with <wsdl:part name="parameter" (remove the s in parameters) and save the file.
d. Right-click the Reference.map file and choose Run Custom Tool to invoke a utility that generates code for XML Web services. This recreates the local proxy.

Internal table in ABAP Server Proxy

Hi Experts,
I have developed a JDBC to ABAP Proxy scenario.
I have a problem. In my ABAP server proxy I have to import the values into an internal table and pass them to a BAPI for GR creation.
I get an error like. OCCURS 0 is not allowed in OO concept.
Can anyone give me examples on declaring internal table in an ABAP Proxy(OO Concept).
Thanks

How to debug XI--- R/3 (abap server proxy) code, SYSFAIL in SMQ2

Hi
i have a XI (BPM) to R/3 (ABAP server proxy) scenario,
when the data goes from XI to R/3, it is getting stuck at R/3 inbound queue (SMQ2), with status : SYSFAIL and error text: "No roll storage space of length
3391496 available for internal storage",
we tried activating the queue/ reexecute the LUW, but it still shows the same error status after running for some time,
how can i debug the ABAP server proxy,
pls tell me how can i debug the ABAP proxy code in the R/3
very critical issue

Sync ABAP Server Proxy - Attachment in Response possible ?

Hi I need to send an attachment in a synchronous ABAP Server Proxy.
I proceeded as follows:
1. design sync inbound interface in PI
2. generate abap server proxy
3. implement this abap proxy
4. tried to attach file to response like this:
    data server_context type ref to if_ws_server_context.
    data attachment_prot type ref to if_wsprotocol_attachments.
    data attachment          type ref to if_ai_attachment.
    data attachments         type prx_attach.
    data lo_protocol         type ref to if_wsprotocol.
    data lo_payload_protocol type ref to if_wsprotocol_payload.
    try.
        server_context = cl_proxy_access=>get_server_context(
        attachment_prot ?= server_context->get_protocol( if_wsprotocol=>attachments ).
        attachment = attachment_prot->get_attachment_from_binary(
            data       = lv_xdata
            type       = if_ai_attachment=>c_mimetype_pdf
            name       = 'my attachment'
        append attachment to attachments.
        attachment_prot->set_attachments( attachments ).
      catch cx_ai_system_fault .
        output-mt_get_documents_resp-fault-fault_text = 'cx_ai_system_fault'.
        output-mt_get_documents_resp-fault-fault_url = 'ERR001'.
    endtry.
However I cannot see any attachment in the response.
Q1: is it possible at all to create attachments in sync server abap proxy?
Q2: if it is, what is wrong with my coding?
cheers
simon:)

Veronica,
    Unfortunately, this was not possible, due to the system EHP state.
First after upgrade this functionality will be possible ( ECC 6.0 EHP5 - corresponding to NW AS EHP2 )
For an example, as Stefan pointed out, you might want to open OSS if your system is up-to-date and you need one.
best regards
Simon:)

Propagate fault message from ABAP server proxy to XI

Hello
My scenario is asynch HTTP -> async ABAP server proxy.
I have searched a forum but I didn't find the ansver on my question:
Is it possible to propagate a fault message from SAP system to XI in case of asyncronous ABAP Proxy in order to see in SXMB_MONI of XI?
I see errors only on SAP side but this solution doesn't satisfied me I want to see all errors in one place.

My iPhone gets a "web server proxy error" connecting to wifi @ home

Ever since installing Comcast Xfinity with Motorola SB6121 and Apple Extreme 5th generation, my iPhone 4 gets a web server proxy error or similar message for any apps seeking to go online. My iPod Touch 3rd generation works as does my MacBook Pro.
I've reset the router, harangued Comcast (no help - it's your phone, sir), rebooted the iPhone, checked all my settings (VPN - what's that? it's not connected), Proxy in the VPN settings is set to off. The phone will show the signal and it will check Apple Mail but Safari, Google APP anything needing web access will either hang or give the proxy error message. Apple Customer Care said call Comcast, Comcast said call Apple & I'm surprised to find little help on the web.
Here's what I found to work on a MacForum sight from 2 years ago.
1.
Settings->WiFi->under choose a network, click the blue arrow (on the right of the network nameyou use)->DHCP
     *now check the IP address with the one on your iPod Touch or computer to see if they are in sequence
     *scroll down to HTTP Proxy & make sure it is off
     -> renew lease may work
It was the making sure the IP address was correct/in sequence which I moved to the STATIC tab and input all the same information (use a screen shot to remember it - home button and on/off button at the same time, it will store in your pictures folder) and give that a shot.
The problem appears to be where multiple machines or devices are using the same router. The iPhone 3GS assigned an IP Address in order of preference, therefore 192.175.1.1 and then 192.175.1.2 etc. The iPhone 4 will assign a strange IP address which the router will not accept. You therefore need to look at the other devices linked and see what number is next in the sequence. Then go to static on the top tab and type in the IP adress manually followed by the Subnet mask, router and DNS details. Once you have completed the info press the DHCP button and HTTP Proxy as off - this is important.
2.
This is how i fixed the wifi problem...(i used my mac)
So basicly I created a new WiFi hotspot on my iMac, then I connected my iphone to it and it WORKS!
1. open System Preferences (Apple -> System Preferences) and click Sharing.
2. select Internet Sharing at the left side.
3. Then check off AirPort.
4. Then creat a newtwork name, and password
5. VOILA! look at the Wifi connections on your iPhone and it should be there!
(IF YOU HAD ANY PROBLEMS GO TO THIS LINK..
http://maketecheasier.com/create-wif...s-x/2009/10/20
THIS SITE SHOWS YOU HOW TO SET IT UP)
3.
reset Network
Same problem, but none of the above worked for me. Finally went to Settings/ General/ Reset/ Reset network settings. Saw this in a different thread.
Hope these help.
Cheers,
cs

This has solved loads of people who have this issue and have used an alternate DNS setting. Below are instructions for both iPhone OTA and on you Mac
If you are getting the error message "Unable to check for update" when you try an OTA (over the air update)
Change DNS Servers
Settings -> Wi-Fi
Click the blue arrow on your connected network
Delete everything in DNS and replace it with 208.67.222.222, 208.67.220.220
Try again

Choose Apple menu > System Preferences, and then click Network.
Select the network connection service you want to use (such as Wi-Fi or Ethernet, unless you named it something else) from the list, and then click Advanced.
Click DNS, and then click Add at the bottom of the DNS Servers list. Enter the IPv4 address for the DNS server.
You can use OpenDNS

You can Google Public DNS if you want

8.8.4.4
