Connect to sap by RFC based on mircosoft windows mobile 5.0
Dear experts,
I have one project about PDA and the develop tool is visual studion 2005. Customer hopes that the PDA device may access SAP R/3(470) system.I can not find SAP BAPI reference in visual studio 2005.
Could you help me?
Thanks and regards,
collysun.
You can access all BAPIs of R/3 4.7 via the builtin Soap-Processor from any Web Service client - including .NET Compact Framework. The Bapis can be found in SAPGUI, transactions BAPI, SE37 and SE80.
For the Soap Processor, see http://service.sap.com/Connectors .

What is the best solution for SAP R/3 4.7 and Windows mobile 5.0 Pocket PC?
Hi All,
I'm trying to connect SAP R/3 4.7 with RFC from Mobile application , now i'm using .net 2005 Windows mobile 5.0 pocket pc. Does Sap.net connector work for this project?
BR,
Prachya.Hi Prachya,
it will not work on a PDA, because the .Net Compact Framework has only a limited instructionset of the .NET Framework and so you run into compile errors. You have to create the Proxies in Visual Studio 2003 anyway, because the .NEt connector requests Visual Studio 2003 for installation - at least this was the case 3 months ago still. once it is created you can import it to Visual Studio 2005 and use it there. But if you try to do that in a PDA App, you run into compile errors - as I said above.
I guess in your case another approach would make more sence - as you are not willing to use MI for your app.
Either you use MS SQL Server in between. On the PDA you can use SQL Everywhere/Mobile/CE (they change the name constantly, but it is the SQL Server for the PDA from MS) and connect it to an SQL server. there is a build in Sync functionality with the SQL server. You will find helpfull introductions on MSDN. And from the SQL Server you can connect to the Backend with your .Net connector. But this solution has its problems, because the build in sync with SQL server is a little tricky - and you need to license SQL server.
On the other hand: you can implement a Webservice, that connects with the PDA. This is possible with the .NEt Compact framework. And from the WebService you connect with your .NEt connector to the R/3 system. This will work fine - but you have to take care of the delta handling.
Hope this helps a little to answer your question - and why not use MI for that?

Consume SAP Netweaver Gateway Web service in Windows Mobile 6.5
Hi All,
I am using Netweaver Gateway Webservice in Windows Mobile 6.5 platform. I know if need to make POST request, first i need to make GET for fetching CSRF token and then passing the CSRF token again with POST request to do the create operation. So i have used the below syntax. But it is always saying as 403 forbidden status while making POST request. I had successfully fetched CSRF token in my get request. Is there any help available for the below syntax?

RFC Connect to SAP with JavaScript
Dear all,
is there a way to directly connect to SAP via RFC using JavaScript. Are there any tutorials or code snipplets?
Kind regards
RomanHi,
If you are running in a windows environment you can use COM functionality to connect to SAP. Here is some example code for you.
[code]
main()
function main()
var txt;
var Row;
var Row2;
var BAPI = new ActiveXObject( "SAP.Functions" );
var Connection = BAPI.Connection;
Connection.ApplicationServer = "xxx";
Connection.Client = "xxx";
Connection.SystemNumber = xxx;
Connection.User = "xxx";
Connection.Password = "xxx";
Connection.logon(0,true);
var Running = BAPI.Add("EW_TH_WPINFO");
var Servers = BAPI.Add("TH_SERVER_LIST");
var Tables = Servers.tables("LIST");
var Dest = Running.exports("DESTINATION");
Dest.value = "NONE";
var CPU = Running.exports("WITH_CPU");
CPU.value = "00";
var List = Running.tables("WPLIST");
Running.Call;
Servers.Call;
for (var enumerator = new Enumerator(Tables.Rows) ;
!enumerator.atEnd(); enumerator.moveNext())
Row = enumerator.item();
Dest.value = Row("NAME");
Running.Call;
for (var enumerator2 = new Enumerator(List.Rows);
!enumerator2.atEnd(); enumerator2.moveNext())
Row2 = enumerator2.item();
if (Row2("WP_REPORT").length > 0){
txt = txt + "\n" + Row2("WP_PID") + "\t" + Row2("WP_REPORT") + "\t" + Row2("WP_BNAME");
WScript.echo(txt);
function jsTrim(strInput)
var strResult;
var objRegex = new RegExp("(^
s)|(
s$)");
strResult = strInput.replace(objRegex, "");
return(strResult);
[/code]
This code just gets a list of current users. Save the file as running.js and fill in the xxx parameters with what is relevent for your system.
You will need wdtfuncs.ocx and librfc32.dll registered on your machine.
Hope this helps.
PS in the widgets forum I have given you an example of how to connect to SAP via RFC within widgets.

Thanks,
Ramat the end of the database instance installation SAPInst is doing some RFCs to the CI.
The logfile states that the gateway on host hostSAP with the systemnumber 09 is not reachable.
Please check if you have started the central instance on this machine.

Rfc conn.: Connect to SAP gateway failed , edit: Group PUBLIC not found
Hello!
I want to create a RFC connection.
In the "Connection and Transport"-Tab I fill out the fields: Target Host, System Number and System ID.
If I save the destination the fields Gateway-Host and Gateway-Service will be automatically filled out with the same input value of the Target Host field.
But there is no gateway for this system and if I ping the destination the following error message is shown:

How can I handle this?Hi,
I have attempted to configure the Destination with a co-worker who successfully configured a Destination to the same R/3-System but with SAP NetWeaver 2004s and not with SAP Netweaver CE 7.1 SR1.
He said that in his case he connects to the Message-Server so we activated Load Balancing.
The Message-Server will be found now but the Logon Group cant be found:

RFC JCo 3 unable to connect to SAP AS with sapgw01 service
Greetings - help is greatly appreciated.
I have an RFC server that uses JCo 3.0.5 to connect to the SAP Application server. When the RFC server is run from a Unix system the gateway service and port needs to be added to the unix systems /etc/services file. We have two (actually 21) sap systems, one has a gateway service id of sapgw00, the other sapgw01. We added both gateway services with port 3300 to the Unix /etc/systems file and are able to connect to the sapgw00 system but not the sapgw01 system. The sapgw01 system is returning the following error. Without sapgw01 in the /etc/services file we get a different error - so it's doing something.
Thanks in advance

... 6 moreHello Sir,
I am a student who is pursuing a project that deals with JCo 3.
I read your question on the forum and think that you have done the JCo stuff and can answer my questions.
Kindly, try to shed some light on following question:
Q1: I simply want to start with connecting my SAP system. I have a user ID and password for the same.
I saw some examples where they use "JCo.createClient(....)" and "JCo.client.connect()" to simply connect the client but
when I type in the code it shows me an error, because they are using package "com.sap.mw.jco" but since I am using JCo3,
I don't have that package instead I have "com.sap.conn.jco" which do not have createClient function.
Q2: By setting the classpath for "sapjco.jar" I was able to compile one of the sample programs but could not run it. Do you
know how to run the SAP JCo program.
Your guidance will be highly appreciated
-Thanks

Number of remote RFC connections to SAP from third party application
Hi All,
We are using an external application which is using the JCO API to make a connection to the SAP server to pass invoices. But the connections are note properly closed after invoking the RFCs and SAP seems to be not able to handle further requests once the numer of connections reach the maximum limit.
Could you tell whether there is a max limit on the number of connections opened to SAP from remote function calls from a third party product?
Is there anyway by which we can make sure that connections are properly closed in SAP after the each remote call?
Thanks in advance for your pointers.
Regards
ArunDear Arun,
Here are the parameter settings which you can do to set up RFC connections to SAP servers.

This will resolve all your problems.

Dears,
I'm developing a Java application (RFC SERVER) with JCo3 and I need to connect to SAP RAC system.
I have configured the TCP/IP connection via transaction SM59, but when I try to start my server I face the error below (dev_jco_rfc.trc):

I only experience this problem when connecting using any BEx component, but, I can successfully connect to the SAP BW system from SAP gui.
Additionally, I have the service 'sapdp02' defined in the services file, both on the workstation and the server.
What could be wrong or missing in my configuration?

Joao.hi Joao,

you may ask basis for help
Symptom
You want to access the customer system using the BEx Analyzer.The connenction fails:The system displays the error RFC_ERROR_COMMUNICATION.In the detail screen, the system displays message "Partner not reached" (host 192.168.4.2, service sapgw 00).
Other terms
SAP Gateway, RFC_ERROR_COMMUNICATION, partner not reached
Reason and Prerequisites
The SAP gateway host is deactivated or the TCP/IP port 33xx (where xx corresponds to the system number) is not open.
Solution
Issue statement ping <IP address> (In this example:192.168.4.2) No reply: Boot SAP Gateway host required.
An answer:Check whether the TCP/IP port 33xx is open (where xx corresponds to the system number) and start the SAP gateway.
The TCP/IP port is also partially defined in the services file as an sapgw<SID> or sapgwxx entry (where xx corresponds to the system number). The services file is in the Windows directory or in WinNT/System32/drivers/etc. -

Acording to me you are faceing this issue because the entry of your backend System is not in the SLD (System Landscape Directory ) of your server.
to make this work you have to make entry in the SLD of your server

Unable to connect to SAP gateway to RFC server failed(hostname unknow)
Hi All,
I am trying to create a new Model(to connect to SAP R/3 server) using the following steps:
1.Selecting Import Adaptive RFC Model
2.Entering Model name,package,default logical system names
3.Selecting the single server option and giving the details of the SAP R/3 server.
When I try to connect it gives me the following error :
-Connect from SAP gateway to RFC server failed.
Also it mentions :
<b>"ERROR hostname 'sapR3' unknown "</b>
Where <b>sapR3</b> is the entry corresponding to the IP address in the host file.
Further I am able to establish a telnet session using the same hostname in command prompt.
I have searched the Internet for solutions, but I haven't found any yet.Any ideas?
Regards,
Kshitij AgrawalHi,
Please check if the hostname that you specify in the "Reimport Model" GUI of NWDS matches with the application server name specified in your R/3 system.The same can be verified by following three simple steps:
1) Open the SAP LogOn.
2) Choose the server to which you wanted to connect and right click on it to get the "properties" in the context menu.
3) Look for the value entered in the field "Application Server" in the properties window.
Hope this helps.
