RFC SDK download

I'm a newbie and purchased ABAP Objects book that has mini-basis system. Is there a way for me to get a copy of the RFC SDK so I can interface programs to my mini-basis system without having purchased a real system? I know there is a service marketplace but registering requires a customer number. 'Initial' is the customer number for a mini-basis system but the site won't accept that.

Hello,
you can get it via the SAP Service Marketplace (SMP). Please have a look at these links:

Download latest SAP NW RFC SDK

Hello,
I need to know where I can download the latest SAP NW RFC SDK (7.20). According to note 1025361 it should be available for the following platforms I need:
Windows x86 32-Bit (Versionen: Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7)
Windows x86_64 64-Bit (Versionen: Windows Server 2003, Windows Vista, Windows Server 2008, Windows Server 2008 R2, Windows 7)
I followed the path mentioned there
http://service.sap.com/patches
-> Browse our Download Catalog
-> Additional Components
-> SAP NW RFC SDK
-> SAP NW RFC SDK 7.11
-> <Plattform>
-> NWRFC_9-20004xxx.SAR
But there is no NW RFC SDK download for Windows x86 32bit, only Windows x64 64bit. But I also need the 32bit SDK. Where can I find it?

I think Windows Server I32 32bit should do it...
I'm trying this out now...

Where can I download NW RFC SDK from?

Note 1025361 gives instructions on where to download NW RFC SDK from. The note also says the binaries are available for "Windows x86 32bit (Versions: Windows Server 2003)" platform.
But when I went to the download center, the binaries for "Windows x86 32bit (Versions: Windows Server 2003)" is not listed. Does anyone know where I can get the binaries for Windows x86_32bit?

Thanks Pinkle.
I downloaded the IA32 bit version of RFC SDK and used it to link my program on a XP machine. I am using VC7 to compile and link my program. I have also downloaded the runtime dlls of VC8 and made sure they are in the path.
Now when running my program it crashes with access voilation when RfcOpenConnection is called (note that this is the first call to the RFC library). Not sure what may be causing the crash.
Any thoughts?

NW RFC SDK: Non-SAP to ABAP with username (trust relationship)

Hello,
I have a quite challenging non-SAP-to-ABAP RFC scenario with a trust relationship.
Hereu2019s the scenario:
An Oracle database server acts as an RFC client and calls RFC function modules in an ABAP server. (I assume the Oracle programmers are going to use NW RFC SDK 7.1 or JCo 3.0 on the Oracle server and call that from their PL/SQL based database application.)
The challenge is that I donu2019t want to use a single u201Ctechnical useru201D on the ABAP side because that would mean that all the users on the Oracle side would be mapped to one single ABAP user. Also, I donu2019t want to have to store individual ABAP passwords on the Oracle side.
Instead, I want the ABAP server to trust the RFC client the same way it might
a) trust a NetWeaver AS Java server after installing the Java serveru2019s certificate in transaction STRUSTSSO2 or
b) the way it might trust another ABAP server after configuring a trust relationship (transaction SMT1?)
The ABAP server should accept incoming RFC connections from the Oracle RFC client with just the user name and no password given and run the resulting processes in the ABAP system under the user id given in the RFC call.
I imagine the ideal solution somehow along the following lines (simplified scenario for a PC-based prototype):
- I download run a program that creates a certificate file (public key?) which I import into the ABAP system.
- The same program creates a matching file (private key?) for the RFC client.
- For reasons of simplicity, let us imagine the RFC client as a stand-alone Java SE application running on a PC.
- The Java SE application uses the JCo library to connect to the ABAP system.
- When opening the connection, it passes a username, but no password. Instead, it passes a Base64-encoded string that was generated by our key/certificate generator program.
- On the ABAP side, the function modules are run under the username used by the Java SE application when establishing the RFC connection.
Is that possible at all? How would you solve this?
Thank you very much in advance and best regards,
Thorsten

Hello,
Thanks a lot for your extremely high-quality replies. Iu2019ve been trying to work with them.
Frankly, just when (after Gregoru2019s and Timu2019s posts) I was hoping that working my way deeply enough into SNC, I would be able to solve my problem, Wolfgang comes along and tells me what Iu2019m aiming at wonu2019t work. Now Iu2019m confused.
The way I understand Wolfgang, the special trust an AS ABAP can put into another AS ABAP or an AS Java (u201Cremote RFC client, give me one certificate and I will accept every username if they come from youu201D) can not be put into a custom-made remote server software (such as the Oracle server application) acting as the RFC client, because when acting as RFC clients, the remote AS Java or AS ABAP use proprietary elements of the RFC protocol which are not available to me when I program my RFC client in the Oracle application.
@Wolfgang, is that correct?
Solution 1: Individual X.509 Certificates
Instead, I can establish X.509-based trust relationships at the level of individual usernames: create a certificate for each Oracle user, import them into the AS ABAP, map them to an ABAP user, and store the certificate on the Oracle side (Iu2019m still note sure about the different certificates and keys used publicly and privately here).
Solution 2: AS ABAP as User Management Engine for the Oracle Application
I can also see an alternative that would spare me the trouble of generating, importing, mapping and storing the certificates: delegate the user management to the AS ABAP and delete the (custom-built) logon and password-checking mechanism in the PL/SQL application:
Users are created centrally in CUA and distributed along with their passwords into (among others) the AS ABAP.
When a user logs on to the PL/SQL application, the username and password are sent for validation to an ABAP BAPI.
If authentication is successful, the AS ABAP returns a SAPLogon ticket which can be stored in the session context of the PL/SQL application and used in subsequent RFC calls. The password (a hash?) would only be transferred once during logon.
What do you think? Would both solutions work or am I still getting something wrong? Can you see a better alternative that would reduce
for solution 1 the administrative overhead for synchronization
for solution 2 the run-time dependency Oracle-ABAP and the change impact on the Oracle applicationu2019s user management concept?
Thanks a lot,
Thorsten

SAP NW RFC SDK throws RFC_INVALID_PARAMETER when running sample programs?

Hi there,
I have just downloaded the latest version of the SAP NW RFC SDK (NWRFC_7-20004565.SAR) for Linux 64 bit from the Service Marketplace and am trying to run the demo programs.
NOTE: I removed the "sapnwrfc.ini" from the current directory so that it would not be used at all..
Also note that I can use the OLD RFC SDK and connect happily to the same SAP system I am trying to connect to below using the SAP NW RFC SDK....so I definetly have the cirrect settings.....
So I compiled a CLIENT test program like:
gcc -m64 -Wall -g ./sflightClient.c -I/home/lynton/Desktop/nwrfcsdk/include -L/home/lynton/Desktop/nwrfcsdk/lib -lsapnwrfc -lsapucum -o ./sflightClient
And then passed in VALID paramters to an SAP system I have access to and I keep getting RFC_INVALID_PARAMETER even though I have not touched the code below in the sflightClient.c program
     loginParams[0].name = cU("ashost");     loginParams[0].value = argc > 1 ? argv[1] : cU("hostname");
     loginParams[1].name = cU("sysnr");     loginParams[1].value = argc > 2 ? argv[2] : cU("50");
     loginParams[2].name = cU("user");     loginParams[2].value = argc > 3 ? argv[3] : cU("user");
     loginParams[3].name = cU("passwd");     loginParams[3].value = argc > 4 ? argv[4] : cU("******");
     loginParams[4].name = cU("client");     loginParams[4].value = argc > 5 ? argv[5] : cU("800");
     loginParams[5].name = cU("lang");     loginParams[5].value = cU("EN");
I have also tried the stfcDeepTableServer.c program....and there I put in VALID settings....(and made the parameters UPPERCASE just like the settings in the "sapnwrfc.ini" file....
serverCon[0].name = cU("PROGRAM_ID");     serverCon[0].value = cU("TEST_SERVER");
        serverCon[1].name = cU("GWHOST");     serverCon[1].value = cU("test.server");
     serverCon[2].name = cU("GWSERV");     serverCon[2].value = cU("sapgw00");
     repoCon[0].name = cU("CLIENT");     repoCon[0].value = cU("000");
     repoCon[1].name = cU("USER");          repoCon[1].value = cU("BCUSER");
     repoCon[2].name = cU("PASSWD");     repoCon[2].value = cU("minisap");
     repoCon[3].name = cU("LANG");          repoCon[3].value = cU("EN");
     repoCon[4].name = cU("ASHOST");     repoCon[4].value = cU("test.server");
     repoCon[5].name = cU("SYSNR");     repoCon[5].value = cU("00");
        repoCon[6].name = cU("TRACE");     repoCon[6].value = cU("3");
I have the UUIDD daemon running perfectly on my box, but yet I keep getting this RFC_INVALID_PARAMETER regardless if I just test the SERVER REGISTRATION or a simple client connection.
I am connecting to a NON unicode system but that would not make a difference.....
Any idea what would cause this? Any help would be greatly appreciated ....
Thanks
Lynton

I have similar problem. My simply program use 7.10_x64_nwrfcsdk for Linux x64 and 7.10_IA32_nwrfcsdk for 32bit Linux. I has been prepared subroutine to convert ASCII to UTF16LE and control 2-byte Unicode length.
Program is working perfectly on x64 environment but didn't work on 32bit. I prepared log for it. In log converted to UTF16LE data are present as hex

and next I use it to loginParams[0].name = ascii2utf16le("ashost"), etc.

Installation of RFC SDK

Hello,
As part of the effort to install BO integration for SAP, i have come across installation of RFC SDK as a prerequisite. I have downloaded the RFC SDK from the market palce (7.00 unicode for Windows 64 bit). But i have been reading up on the internet that RFC SDK can be installed as an add on component while installing SAP GUI. I tried doing this using both, SAP GUI 7.10 (compilation 2) and SAP GUI 7.20 but can't find this component for selection. Am i missing something?
On the other hand, i have the SAR file downloaded. I have already installed SAP GUI on the Business objects server. Do i install the RFC SDK on the Buisness Objects host (server)? I have unpacked the RFC SDK SAR file but am not sure, which directory / subdirectory to put it under.
How do i go about this?
Regards,
Prashant

Hello Ingo,
For Windows Installation, the document only mentions on page 43 that the RFC SDK needs to be downloaded and installed but nothing else. i have put the file librfc32.dll in the system32 folder as directed. I have put the Java connector files in their respective directories tough.
i have used Java connector 2.1.10 64 bit X86 on a windows server 2008 (AMD Opetron). The directory for BO is Programfiles X86.
I went ahead and installed BO integration kit (without RFC SDK files though). The installation went well. But after that when i start infoview, and click on Document list it comes up with the error
The requested resource (/PartnerPlatformService/actionAuthFilter.do) is not available
In CMC i can now see SAP in the Authentication tab but when i try to open it i get the same error as above. I have read on an SAP note that for this error re deploying the WAR files on Tomcat works. Is that right?
Thinking again, can i still place the RFC SDK files in the proper directories now? but i still have no clue where to put them (directories). Am i missing something from the document?
Regards,
Prashant

RFC SDK

Hi
I am completely new to SAP.
We are investigating the possibility of coupling of our middleware solution (which is a C application) to SAP systems.
As I understand it the RFC SDK is the appropriate tool for this.
I have, however, two questions:
1. Is this RFC interface available for SAP systems based on the ABAP & Java NW application servers?
2.Is there a possibility of downloading a trial version (or buying a trial license) so that we can explore the functionality of this interface?
Best regards,
Simon

Hi Simon,
Here are answers
You can use our RAC systems to explore the funtionality
To know more about our RAC service

Please read our RAC service and please let me know your decision.
PS: RAC service standard suits your need.
Thanks and regards,

RFC SDK Functionality

Currently I am investigating the feasibility of introducing a SAP coupling in our middleware product.
We want to use the RFC SDK to achieve this.
Therefore I have some questions about the functionality of this interface:
1. Is it possible to retrieve data from a SAP system using this interface?
2. Is it possible to retrieve 'all changes since a certain timestamp' using this interface?
3. Is it possible to retrieve a list of all objects /tables in the system?
4. Is it possible to perform a 'describe' of an object (what attributes does it have? what keys?).
Thanks!
Simon

NetWeaver RFC SDK for AIX

Hello!
I'm looking for the new NetWeaver RFC SDK for AIX 5.3 (64bit) for compiling the sapnwrfc perl module.
According the following note it should be available: https://service.sap.com/sap/support/notes/1025361
However i can not find a downloadable file in the service marketplace.
Is the AIX version not available right now?
thanks in advance

Hi again,
the Sap note I've mentioned in the original post is not the right one. The correct Sap note is 1025361 "Supported platforms for the NetWeaver RFC library and SDK".

SAP Netweaver RFC SDK bindings for Node.js

Hi all,
I have just completed a first version of bindings to the SAP Netweaver RFC SDK for [Node.js|www.nodejs.org].
You are encouraged to inspect and download the source code on [https://github.com/jdorner/node-sapnwrfc|https://github.com/jdorner/node-sapnwrfc]. For further convenience, I have also supplied a package for use with the node package manager (npm). Nevertheless, you will have to download the SAP NW RFC SDK beforehand. Thus, you should carefully read the README on GitHub for more detailed instructions.
Please let me know if you have problems installing/compiling the module. At the moment it has only been tested on a x86_64 linux platform.
Regards,
Joachim

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

Getting metadata for RFCs using RFC SDK (with position of parameters)

Hi!
I'm currently using the RFC SDK Function "RfcGetFunctionInfoAsTable" to retrieve metadata for RFCs from SAP. What i see is that the "Position" field in the RFC_FIELDS_U structure contains arbitrary values, and so I am not able to determine what is the actual ordering of the parameters.
What can I do to determine the exact ordering of the parameters of an RFC? (ordering as in - I want to obtain the parameters in the same order as they appear in SAP GUI).
Thanks,
Mustansir

Hi,
I think you can use the code similar to the one below...
some of the things not covered in this are
1. all types for which   CALL FUNCTION 'RFC_GET_NAMETAB' is not returning result, you can call CALL FUNCTION 'RFC_GET_STRUCTURE_DEFINITION' directly. I have not covered that in this code. Hope this is helps in resolving your issue.
Also, the code is not optimized. So there is some scope for optimization of this code.

RFC SDK support on solaris-intel?

I have some questions about the C SAP RFC SDK. I cannot seem to find a complete list of supported UNIX platforms.
What is the current version of the C RFC SDK?
Is it supported on the solaris intel platform?
I notice that the dynamic version of the RFC library (rfc32.dll) is installed with SAP Netweaver on Windows. Is the equivalent dynamically loaded library (i.e. librfc.so) always included with a SAP installation on UNIX as well? Does this mean that the static libraries provided in the RFC SDK are no longer required to build a client RFC application, since a client application can dynamically load the run-time library instead?

We don't certify Solaris on NT.
          You can find this information on platform support page.

NW RFC SDK: No more human-readable RFC error messages?

I'm converting my program from the classic RFC SDK to the NetWeaver one.
Apparently, the RFC_ERROR_INFO.message value is no longer filled with the proper human-readable error message as it used to be.
Eaxmple: trying to create a function description for a non-existant function
Classic SDK: "Function module "Z_MYFUNC" not found."
NetWeaver SDK: "ID:FL Type:E Number:046 Z_MYFUNC"
I don't see how to get the old message back. Can anyone help? Thanks!
