Hi All,

We are trying to connect to SAP using NCO3 connector using .net application. We have followed the blogs available and looked how to solve the errors but still no success. Can some one help me here? The same connection parameters are working fine when  I try from the SAP Logon pad.

All the blogs point to the connection parameters but the same is working fine when I use from the SAP Logon pad so not clear on why its not working from the application.

We are passing the below parameters.

            parms.Add(RfcConfigParameters.AppServerHost,

            parms.Add(RfcConfigParameters.SystemNumber,

            parms.Add(RfcConfigParameters.SystemID,

            parms.Add(RfcConfigParameters.User,

            parms.Add(RfcConfigParameters.Password,

            parms.Add(RfcConfigParameters.Client,

            parms.Add(RfcConfigParameters.Language,

Below is the Error description

I've got the following error within my tRFC Server Integration.

"RfcServerError occured in RFC server: xxxx RFC Caller System ID: yyyy function Name: ARFC_DEST_SHIPError type: RfcUnsupportedPartnerExceptionError message: Non ABAP RFC Client not supported."

According to the Forum the Change from "NON-Unicode" to "Unicode" or vice versa in SAP in Settings of relevant Program-ID takes no affect.

Hi to all

I need youradviseplease

We have EWM system connected to external system withsqlserver and .net connector

Nowevrytime we have themicrosoftevent 4227

TCP/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint. This error typically occurs when outgoing connections are opened and closed at a high rate, causing all available local ports to be used and forcing TCP/IP to reuse a local port for an outgoing connection. To minimize the risk of data corruption, the TCP/IP standard requires a minimum time period to elapse between successive connections from a given local endpoint to a given remote endpoint.

andin the logs of the .net connector I have the error

Hi,

I run into a strange problem with .net Connector version:

SAP Connector for Microsoft .NET 3.0.16.0 for Windows 64bit (x64)

The connector should establish a connection through an SAP Router with password and returned this error message:

2015-11-23 10:38:57.526 RfcConnectionPool.GetPool threw RfcCommunicationException:

The error can be reproduced with the example program from Tutorial:

After playing a little bit around, I fixed the problem by replacing the '§' in SAP Router password with '$'.

The connection string /H/w.x.y.z/S/3299/W/x$xxxxx/H/192.168.s.t works fine.

The ugly thing is, SAP Logon accepted the "x§xxxxx" in password and connected without problem and Visual Basic components (wdtfuncs.ocx, SAP.Functions) work without problem with '§' in password. JCO not yet tested.

Dear Sir or Madam,

we have a solution for managing printers in our client's environment.

We now want to expand our abilities to pushing these printer connections from our application into their SAP systems.

Is there a way to accomplish this task using the sap .net connector?

If not, what would be the appropriate approach to accomplishing this task?

Thanks in advance for your assistance.

I am trying to call the SAP RFC ZSL_QMFM_003 remotely using SAP .NET Connector 3.0.16

When set the values get exception

the integer length of value "I_MGEIG" is 13,but use SetValue() input more than 10 ,get the exception.How  to solve this?

I'm using the RFC RSDRI_INFOPROV_READ_RFC to read some data from DATACUBES.

IRfcFunction funcaoRT = repo.CreateFunction("RSDRI_INFOPROV_READ_RFC");

funcaoRT.SetValue("I_INFOPROV", "/CPMB/Z0IMVWV");

RfcStructureMetadata strucmetadata =newRfcStructureMetadata("RSDRI_S_RFCDATA");

Hi there.  We have a number of Web Applications that perform basic read-only RFC calls to SAP through the .NET Connector using a basic system user login created specifically for our web apps.  Occassionally, however, we create CustomDestinations using SSO to perform various write RFC functions using the actual user's SAP login.

This works great.  However, I am noticing in T-Code AL08 which shows all users logged on that the Custom Destinations persist.  Should we dispose of these somehow in our .NET code?  Is there a safe way of disposing of the Custom Destination after it is no longer needed?

For example, should I use the Shutdown() method after the Custom Destination is finished invoking the SSO RFC? Or RemoveDestination() possibly?

Thanks!

Hello everybody!

I'm calling a RFC using the nco 3.0, but I'm having a problem with the amount of connections when testing concurrent calls.

I am using the following parameters regarding the pool size and connection limit in the destination configuration:

parms.Add(RfcConfigParameters.PoolSize, "5");
parms.Add(RfcConfigParameters.PeakConnectionsLimit, "20");                        

My problem is that if, for instance, I have 10 threads calling a RFC at the same time from the same server and with the same user, for some reason I would like to know, only 2 of those requests are executed at a time. Also if I check the SM04 transaction, I see 3 rows corresponding to the user and server I'm using to call the RFC with nco.

So, to me it looks like those parameters are not having any effect at all, and even the default value of 10 for those parameters is not working.

What am I missing? Need some light in my way! :-)

Thanks in advance.

Hi ,

I am pretty new to SAP, and I have got a new requirement where I have to Implement a C# windows service that would be called from SAP RFC.

the work on SAP side is almost done by SAP team, I am looking forward for a C# code to a windows service that would receive some parameters from SAP. Any hekp would be appreciated.

PS: I am trying to connect SAP via SAP.NET 2.0

Thanks in advance!

Hi to everybody,

I'm using:

- Visual Studio 2013

- nco30 x64

The aim is obtain the values from some fields from table "header" and table "components" relevat to the BAPI_PRODORD_GET_DETAIL

Surfing in the web, I found a post from Ronald Lim and I followed the steps described by Yearden Jacobson

I'm trying to use BAPI_PRODORD_DETAIL this is my code:

Private Sub GetProdOrdDetails(ByVal odp As String)

        Try

            Dim funcAPI As IRfcFunction = _ecc.Repository.CreateFunction("BAPI_PRODORD_GET_DETAIL")

            funcAPI.SetValue("Number", odp)

            Dim myTable As IRfcTable = funcAPI.GetTable("Header")

            Dim myElementMetadata As RfcStructureMetadata

            myElementMetadata = myTable.Metadata.LineType

            funcAPI.Invoke(_ecc)

            For i As Integer = 1 To myElementMetadata.FieldCount - 1

                MsgBox(myElementMetadata.Item(i).Name)

                MsgBox(myElementMetadata.Item(i).Documentation)

            Next

        Catch ex As Exception

            MsgBox("Error:" & ex.Message)

        End Try

    End Sub

No matter to get the fields name, description and so on, but I need getting the values for each field in the tables, but I don't know how to do.

Is there anybody who knows how?

I thank you in advance

Kind Regards

Hi,

I am using SAP BizTalk adapter with NCO to connect with SAP. I have followed all the instructions on the BizTalk adapter (https://support.microsoft.com/en-us/kb/3100811). I have also installed the SAP .NET connector.

When I try to connect I am getting the following error:

Connecting to the LOB system has failed. Destination NCoConnection does not exist.

Note: I can successfully connect to SAP using BizTalk adapter for SAP with the SAP librRFC assembly

Any idea on why I am getting the above error. Thanks in advance.

hi All,

I have installed SAP.net connector 2.0 in my system and i am trying to reference the SAP dlls in my VS 2003, but i am unable to do so.

can some one please help me what am i missing here?

We are using the RFC SDK for RFC Server and in that we are calling the SDK function RFC_REMOTE_EXEC to pass a table parameter to the RFC server...

Now I want to move on to NCo 3.0 platform and I want to use the same server function RFC_REMOTE_EXEC as I dont want to discriminate the Servers running NCO and SAP SDK . Can anyone help me out in implementing this....

I am using the Below ABAP code at SAP:

CALL FUNCTION 'RFC_REMOTE_EXEC' DESTINATION DEST

           EXPORTING

                     COMMAND = 'LISTN'

          TABLES

                     PIPEDATA = TABLE                //Passing The Table

          EXCEPTIONS

            SYSTEM_FAILURE        = 2.

       ENDIF.

NCo Server Code:

[RfcServerFunction(Name = "RFC_REMOTE_EXEC")]

    public static void RfcServerFunction(RfcServerContext ctx, IRfcFunction function)

    {

        string reqtext = null;

        RfcDestination rfcDestination = RfcDestinationManager.GetDestination("Qua");

        RfcRepository rfcRepository = rfcDestination.Repository;

        IRfcStructure rfcStructure = rfcRepository.GetStructureMetadata("S_TABLE").CreateStructure();

        Console.WriteLine("Received function call {0} from system {1}.",

        function.Metadata.Name,

        ctx.SystemAttributes.SystemID);

        IRfcTable rfcServer = function.GetTable("TABLE");

        if (rfcServer.Count == 1)

        {

            reqtext = rfcServer.GetValue("SHNUMBER").ToString();

            Console.WriteLine("REQUTEXT = {0}\n", reqtext.ToString());

        }

   }

When I am calling this function at DEST SAP is giving SYSTEM_FAILURE excepection.

Error log generated at .Net Server is as below.

Hi,

can someone please throw some light on what all necessary SAP log on info do we require while adding a new application server using the NC0 2.0

In the below steps I am currently stuck at "d."

Add an SAP proxy to the application as follows:

a. `From the VS.NET menu, choose Project Add New Item

b. Select the SAP Connector Proxy template and choose Open.

c. In the VS .NET Server explorer, right-click on SAP Servers and select Add Server.

d. Complete the SAP logon information and choose ENTER.

e. The folders BOR and Functions appear. If not, recheck your logon information.

when i enter the username, password, system number HTTP Host details then the folders BOR, Functions appear in server explorer but none of the RFC in the SAP Server appear in the list. Am i missing any necessary Log on info here.

any help would be much appreciated!

thanks!

Hello we are trying to setup SSO for .NET based application which will be accessed from iview in SAP portal and will be connecting to SAP ECC6 for data using RFCs.

we have SSO setup between SAP portal (Ticket issuing system) and SAP ECC6 EHP6 (as trusted system). Now when we login to iview which has our app URL it asks for user name and password.

we are using MYSAPSSO2 cookie to login but its not working; is there any other setting or trust relationship required between IIS and SAP portal or IIS and SAP ECC6?

We haven't done anything with respect to IIS to set up any trust relationship and we think this could be the reason we are not able to login yet using SSO logon ticket. Appreciate any help.

Do we have to configure SNC on SAP ECC6 EHP6 in order to have SSO work with .NET app?

Hi,

Is there any .NET library available for SAP Netweaver AS Java - SPML connector.

SAP provides mxopenspml.jar for java developers to create and send SPML requests to Netweaver AS Java systems from a standalone Java application.

Is there a similar library available for .NET developers to create and send SPML requests from standalone .NET application.

Thanks in Advance.

Shivam

I have a very similar problem to the one posted below from a few years ago but has been unanswered.

Re: SAP.Net Connector 3.0 with SSO failed

We have a .Net4.0 web app running on IIS7.5. It runs in a corporate environment (with Kerberos/Windows Auth) and needs to connect into an SAP backend using RFC via the .Net Connector. I'm trying to use SNC and delegate/impersonate the users through the web app.

The web app (IIS) is configured very similar to the instructions here:

http://blogs.msdn.com/b/chiranth/archive/2014/04/17/setting-up-kerberos-authentication-for-a-website-in-iis.aspx

I'm using a service account for my app pool have it setup with unconstrained delegation. It has a SPN to my webserver. I think my delegation is configured correctly because I have tested it connecting to other IIS servers and I'm able to pass my user's Kerberos information.

In my web app, I have the SNC configuration set as so:

RfcConfigParameters.SncMode = "1";

RfcConfigParameters.SncLibraryPath = @"C:\qgsskrb5.dll";

RfcConfigParameters.SncPartnerName = "p:sap@sub.contoso.com";

RfcConfigParameters.SncMyName, "p:myId@sub.contoso.com";

The SNC library we are using was taken from a SAP GUI client. When I run my web app locally, it is able to connect into SAP. However, when I deploy the app to my webserver and try to connect through it, i get the following error:

GSS-API(maj): No valid credentials provided (or available)

GSS-API(min): No Kerberos SSPI credentials available for requested name="p:myId@sub.contoso.com"

I'm guessing there is a delegation problem in the SNC connection but I'm having troubles determining why.

Any help would be much appreciated!
