SAP.Connector.Rfc.dll installing to 2 directories

I am installing SAPGUI Frontend components including the BW and BI add-on components on a Windows XP/SP2 system with .NET 1.1 already loaded.
I've read on this forum that SAP.Connector.Rfc.dll and other .NET assemblies are installed to the GAC, but I saw on a test machine where this assembly (and others) were installed to both the GAC and to the ProgramFiles\sap\frontend\bw directory as well.
Is there a requirement for the .NET assemblies to be in the bw directory ( or other private SAP directory as opposed to the GAC? )
If anybody from SAP knows the answer, it would be much appreciated. Thanks!
Thanks,
Owen

Hi Sowmya C,
How are you doing ?
Upon addition of any SAP component, the reference is added automatically.
However, in the event that the reference to "SAP.Connector.dll"
is not present, you can add it through the references tab, provided that the SAP.NET Connector is installed on the local machine [as this will allow you to add the dll reference locally, like you would reference anyother local assembly]
It is of type .NET dll
with respect,

SAP.Connector.Rfc INVALID_QUEUE_NAME

I have an application that is using the .Net Connector 2.0 to access some standard and custom BAPIs in SAP.
Occasionally when calling the BAPI_CUSTOMER_CHANGEFROMDATA1 BAPI from the application the .Net Connector throws an exception. The Source of Exception is SAP.Connector.Rfc. The Message is INVALID_QUEUE_NAME.
I havent been able to find any information on this error message in the SDN archives or in the Connector documentation and would be grateful for any insight that anyone can offer.
Helga (for James Green)

Rainer,
I think the answer is that we dont really know what kind of exception it is, Im sorry. The only way to find out would be to trap that in code, and our 3rd party product provider will do that, but that wont be before next week.
At the moment all I have is the source and message of the exception.
Hope you or someone can still help.

SAP Connector 2 - Could not load file or assembly 'SAP

Hi all,
I've recently installed SAP .NET Connector 2 and have been developing a basic C# web form to interrogate the customers table. I have created all my code and done a successdul build. However, when I try to run the web form I get the following error:
<i>Could not load file or assembly 'SAP.Connector, Version=2.0.0.0, Culture=neutral, PublicKeyToken=50436dca5c7f7d23' or one of its dependencies. The system cannot find the file specified.</i>
The SAP.Connector.dll and SAP.Connector.Rfc.dll files are on both my development machine and the server I am deploying the project on. Any ideas ?
Thanks.

Fixed it myself. In the solution browser, expand the reference section and in the properties for the SAP.Connector and SAP.Connector.Rfc set the 'Copy Local' parameter from False to True. This fixes the issue.

Librfc32.dll installing Documentation

I found in SAP .NET Connector Documentation that the librfc32.dll is required.
I could not found any documentation about installing the librfc32.dll in the framework web server.
Please can you tell me if there are any other requirements besides sap.connector.dll and sap.connector.rfc.dll ?
The full documentation is needed for my system administrator for installing the product.
thanks.

Hi Reiner,
1.
Just wondering , if librfc32.dll file was packaged with application for its end user customers- would it be necessary that it be used by SAP system authenticated users only ?
2.
Will it not raise any licensing/distribution concerns, as in like a third party (non-SAP) giving out librfc32.dll with their application ?

File or assembly name SAP.Connector, or one of its dependencies not found

Hello there,
Something very strange is overcoming me when experimenting a little bit with the SAPConnector:
I developped a class that is accessing the proxy-class generated by the SAPConnector wizard and I have put it into a class library. No problems so far.
When I am accessing the class library from into a windows application, no problems are signalized...
However when I try to execute the BAPI from another class library project, I always get the following message:
File or assembly name SAP.Connector, or one of its dependencies, was not found.
I am testing with the following configuration:
- Visual PC 2004
- .Net-framework 1.1 and .Net-framework 2.0
- Visual Studio 2003 and Visual Studio 2005
I tried both SAPConnector 1.0.3 and 2.0, but both return the same message.
Thanks in advance!
Greetz,
Sven

SAP.Connector.DLL (and SAP.Connector.Rfc.DLL in 2.x) must be available for the project to load. The easiest is to put the two DLLs into GAC (which is the default in NCo 2.x). You can also have them in you application directory. The reason that you don't see a problem if you are using NCo directly is the fact that VS automatically copies directly referenced DLLs into the target directory. This is not (allways) the case for inderectly referenced DLLs.

Problem using SAP Connector in Win 2k3 x64 - No Data is returned on BAPIs

Hi,
During the tests of migration to a 64 bits environment we encountered some problems with the connection to the SAP server.
The first problem was that the librfc32.dll library was a 32 bit library, so application could not run in x64 mode.
We downloaded the official x64 library from the Support Portal (https://websmp206.sap-ag.de/support > Downloads >
Support Packages and Patches > Entry by Application Group > Additional Components > SAP Kernel > SAP KERNEL 64-BIT > SAP KERNEL 6.40 64-BIT >
SAP KERNEL 6.40 64-BIT > Windows Server on x64 64bit > #Database independent > librfc_66-20001176.sar, and extracting file librfc32.dll a x64 dll).
Using this x64 dll we finally could test the application in 64-bits mode (the purpose of the migration) testing its runtime behavior,
where my current problem is.
When connecting to the SAP server all BAPI's we test are always returning an empty data results.
We have no errors nor exceptions from the SAP .NET connector, only the results come empty when they shouldn't.
When testing the same application but linked to the SAP 32 bits library (application runs in 32-bit mode), invoking the same BAPI's
(using the exactly the same code and parameters) we got the correct response from the BAPI, i.e., non empty results.
We already tested a set of BAPIs and always with the same result, in x64 we got no data, in 32-bits we got the information.
Does anybody know what can be causing this misbehavior? What can we do to make application run correctly in x64 mode?
Here some additional information about the Operating System: Microsoft Windows Server 2003, Standard x64 Edition, Service Pack 2 (with all windows updates installed).
Best regards,
João Portela on behalf of Manuel Dias

Maybe your application isn´t run in x84
#Go to properties of your project ->Build -> changed platform target of "Any CPU" to "x86"
#Copy these libraries from our 32-bit environment :
*SAP.Connector.dll
*SAP.Conector.Rfc.dll

Crash in SAP NetWeaver RFC SDK DLL

Hello community,
I have a problem with the SAP NetWeaver RFC SDK. Once in a while I get a crash with such error message:
Unhandled exception at 0x000007FEF1D3DD6E (sapnwrfc.dll) in bridgeserver.exe.22108.dmp: 0xC0000005: Access violation reading location 0x0000000000000008.
Basically I get function metadata, set the call parameters using the API calls and call RfcInvoke. It crashes. The callstack is:
sapnwrfc.dll!000007fef1d3dd6e()
sapnwrfc.dll!000007fef1d56613()
msvcr80.dll!_CallSettingFrame ()
msvcr80.dll!__CxxCallCatchBlock ()
ntdll.dll!RcConsolidateFrames ()
sapnwrfc.dll!000007fef1d5653a()
sapnwrfc.dll!000007fef1d2c4f7()
call RfcInvoke from my code
I've got the call stack from one of the two crash dumps I've got. I took a look on the registers and assembly of the top frame and it looks like an indirect acces to a field of a structure but the pointer to structure is NULL.
Is there any way I can debug it further? I'm already pretty sure that the parameters to RfcInvoke are correct (no messed-up pointers).

Thanks Mike,
For example we want to executie Function Module and need to prepare/allocate TABLE parameter.
In doing so we need to invoke function RfcGetStructureDescHandle is described in doc.
However, we cannot find it anywhere in H files under SAP NW SDK 7.10 dir structure.
Do you have an example of how to create a TABLE parameter (export for example).
We are going to reproduce the symptom with the demo source distributed with the SDK.
Any help/suggestions is greatly appreciated,
Alfonso

Installation Error - SAP Unicode RFC Library Not Found

Out of approxoimately two dozen successful client installations of the BObj Integration Kit for SAP Solutions (SP2), I have one user who gets this error: "The SAP Unicode RFC Library could not be found. This library is available as a part of the SAP Frontend, which is a pre-requisite for the installation of this software. Please install 'Unicode RFC Libraries' feature in SAP GUI Installer 710 installer, then re-run this setup."
The problem is that this user is running the exact same Integration Kit installation on top of the the exact same SAPGUI installation that has generated successful results for all other client installs on our team. Why would this probelm be happening for one particular user? (Problem is happening on a Windows XP client system, but as I've mentioned, all other installs on a Windows XP client have been fine.)
I've reviewed OSS Note 1372466, but it indicates that the problem resides on the SAPGUI server side. Regardless, I have only one client generating this error out of many what appeared to be identical clients that installed successfully.
Any ideas would be much appreciated.
Thanks,
Josh

Thanks, Ingo. A missing librfc32u.dll file seemed to be the problem. Interestingly, the problematic client had this dll in a couple of places, but not in the c:\WINDOWS\System32 directory. Why that dll wasn't in the right place for one particular client is a question for a different forum.
Thanks,
Josh

SAP.connector.rfcLogonException with SAP Connector

I'm having an error when I try to connect to SAP:
SAP.connector.rfcLogonException: You are not authorized to logon to the target system.
The code is part of a sample program located in CodeProject, the example is complete. I can't install the .Net Connector because I use C Sharp express, so the program doesn't install.
Any help?
TIA

Assing the profile R3_BASIC to RFC user id in SU01 and try it.

SAP Connector Proxy Wizard doesn't start

Hi all,
I've just installed VS2003, the SAP .NET connector and the .net framework (1.1) on a freshly installed Windows XP pro machine. If I follow the various tutorials on the web I should be able to create a SAP proxy when doing the following:
- start VS2003
- create a new Windows Application (in C#)
- Add a SAP Connector Proxy
-- A wizard starts
And that is were it starts to go wrong. Instead of a wizard, I get the following:

</wsdl:binding>

Does anyone know what could be wrong here?
Thank you and kind regards,
Thomas

Hi Thomas,
With the newer version of NCo (> 2.0) there is no wizard. You would have to drag and drop the RFC/BAPI from the server explorer window of visual studio.
First open the solution explorer, click on the SAP icon. Specify the credentials. And then from the list of RFC/BAPI drag and drop on SAP connector proxy page(design view). You can also specify the filter to restrict the listing of RFC/BAPI.
Regards.

Can't see SAP Connector Proxy

Hi experts,
I'm trying to use SAP .Net Connector 2.0 or 3.0 on visual studio 2003, 2005, 2008 or 2010
to call ABAP function modules via RFC .
I have the same problem, once installed the right connector, if I try to add the item SAP Connector Proxy to my project
but I could not find it as option.
Another problem then is yhan I can't connect to my SAP server that is on an external network, even if I reach the
system via SAP Gui.
My tought is that I can't find the Connector because I'm not connected to the Server, but in some forum I found
suggested to first add the item Connector to the project and then connect to the SAP server.
Please if you have some experience also in only one of this problem replay to my thread,
I need to implement the whole thing as soon as possible, every help will be appreciated!!
Greetings,
Paolo F.C.

Sap connector with Minisap

Hi,
I'm need implement a project for access sap r/3 with visual studio 2005. I will use SAP connector dll, but I need to test the access first in MiniSAP. Is this possible?
Regards
Balbino

Dear Guys
I am using SAP 4.6 C and do not want to upgrade it for time being. Basically working on personel project and trying to connect SAP4.6C with a webserver using ASP.NET and .NET Connectors installled in middleware server.
WebServer (ASP.NET) -
> Middleware (C#) -
> SAP4.6C
I want to transfer data from webserver in XML format to middleware and from middleware to SAP using RFC or IDOC.
My question is regarding event triggering that is when an XML file is submitted to Middleware, how middleware can know that a file has been reached and will be sent to SAP.
I have already tried the direct call from WebServer to SAP and it working fine but I want a middleware solution in between in form of C# and .NET Connector.

The contractor that installed this, thinks the next area to look to is to see if the SAP EP has been configured somehow to stop outgoing http traffic from applications running within it... Maybe the EP is blocking outgoing HTTP access, although other components from the EP are working OK.
How can we check this?
Please advise.
Kind regards.

Can someone tell me if I can connect to SAP from VS2005 and how?
Thanks in advance

Hi,
SAP Connector for MS .NET is not currently supported on Visual Studio 2005.
Please check the article Using SAP Connector for MS .NET (NCO) in Microsoft Visual Studio 200 to learn a workaround that enables easy design-time connectivity to SAP back-end systems in Visual Studio 2005 by creating the connector proxies in Visual Studio 2003 and porting them to Visual Studio 2005.
