SAP RFC SDK - install help

Hi,
I'm trying to install saprfc for PHP <http://saprfc.sourceforge.net/>.
I've downloaded the SDK file as a .SAR archive from <https://websmp206.sap-ag.de/SWDC>. I understand that I need SAPCAR to decompress this file.
I've downloaded the SAPCAR file appropriate to my 'NIX operating system. However, the file is a ".EXE" Windows file which I cannot run or open with any utility.
Is there something I'm missing when trying to download and install SAPCAR?
Thanks,
Rob

you need to move the .SAR file and the SAPCAR.exe on the same folder (ie. x:\<name_of_the_folder> )
then open a command prompt go to the folder you created and type:
SAPCAR -xvf <b><name of the .SAR file></b>
This will uncompress the file and then you can move the contents to any other OS via telnet.
Hope this help!

SAP RFC SDK 7.10 Compilation Issues

Hello ,
We have a Pro*C program that is using the RFC SDK 7.10
When we are compiling our program with Pro*C Compiler in HP UX 11iv2 os we are getting the following errors:
SAP_U16_PROTOTYPE_STDC(mkstemp)..1 PCC-S-02201, Encountered the symbol "mkstemp" when expecting one of the following: Error at line 1895, column 1 in file /home/psoni/rfcsdk-710/orgseclib/sapuc.h SAP_U16_PROTOTYPE_UO(dirname) 1

The symbol ";" was substituted for "SAP_U16_PROTOTYPE_UO_HLP" to continue.

I had checked the files sapuc.h and sapucx.h are correctly included in my program.
Also I checked for the errors : that the reference of some constants like
SAP_U16_PROTOTYPE is present is sapuc.h - However I am not able to
identify the cause of compilation issues.
Please can anyone guide me - or give any hints as to how this compilation issues can be resolved.
On sap rfc sdk version 6.20 with HPUnix 11iV1 we did not face such problems. Post that release we have tried all libraries including 6.40 and all of them are giving the above errors.
Thanks for the help.

This compiler error looks really strange.
Without your sources (of the affected file) and the full command line it's impossible to suggest something.

SAP RFC SDK 7.1 Unicode - Supported OS

Hi,
Where can I find info about the list of Supported OS for sap rfc sdk.
Specifically, I am looking for info about RfcSdk support for Windows 7 and WIndows 2008 R2.
Any help would be highly appreciated.
Thanks,

Unable to extract SAP RFC SDK 6.x/7.x

Hi,
I downloaded SAP RFC SDK 6.2,6.4,7 and 7.1 and tried to extract it using SAPCAR.Unfortunately I can't extract it. SAPCAR says: "error opening <filename>
Using Windows XP, IIS 5.1
Thanks in advance

Hi,
thanks for answering that quickly. Unfortunately, there's still the same error ;( Any suggestions?
Edit: Here's a screenshot: http://img507.imageshack.us/my.php?image=3006nb4.png
As far as I know, it should be possible to open the .sar file with winzip/winrar, right? If I'm trying to open the .sar file with winrar, an error pops up: "corrupted file...:"
Thanks in advance,
Martin

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.

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:

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!

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

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

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.

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

SAP NW RFC SDK

Dear All
I have unpacked SAP NW RFC SDK inside the /Program Files/SAP/FrontEnd/SAPgui/.
As a result new Folder nwrfcsdk is created.
When I tried to run(at the command prompt) the one of the EXE file present inside the /nwrfcsdk/bin, I get a message "This application has failed to start because SAPNWRFC.dll was not found".
But I can see the said DLL inside the /nwrfcsdk/lib folder.
Is their anything needed to link the /nwrfcsdk/lib and /nwrfcsdk/bin folders ?
Please help to over come this issue !

To upload a data into SAP Table with the help of RFC function in BODS

Hi,
Please provide me step-by-step solution to upload data into any SAP table with the help of RFC function in Data Services.
I have created RFC function that upload data into SAP table. RFC Function contains one table that has same structure as my database table.
In the data services how can i filled the table of RFC function, i am using this function in query transform of data services but it gives me error.
I am also follow link http://wiki.sdn.sap.com/wiki/display/BOBJ/BusinessObjectsDataServicesTipsand+Tricks
but it did not help me.
Thanks,
Abhishek

Hi Abhishek,
Did you import the function module in the SAP datastore first? When you open the SAP datastore, the function should be listed in the 'functions' section. If not, import it. Make sure your function is remote executable.
Once the function is there, you can use it in a transformation. In 'Schema Out' right-click on 'Query' (top level) and choose 'New Function Call'. You can then select a datastore and a function in the datastore. The wizard will show you which output parameters are available. I believe you have to add at least one and can select as many as you like.
After confirming your selection the function and the output parameters appear in Schema Out. You can then right-click on the function and choose 'Modify function call'. A popup will appear where you can specify the input parameters.
I hope this helps.
Jan.

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...
