Can't connect to SAP R/3

[ptnull]

Hello,

i'm trying to extract data from SAP R/3 However when it goes trough Method
public IRfcFunction CreateFunction(string name);
I always get the following error:
An unhandled exception of type 'SharpSapRfc.SharpRfcCallException' occurred in SharpSapRfc.Plain.dll
Additional information: Function metadata lookup: unsupported backend version: -1

I can use older version of SAP connector not supported in this project, and I notice it have this property on older .net connector versions, not on NCO3
[Browsable(true)] [Category("General")] [DefaultValue("3")] [Description("RFC server type, 2/3/E/F: R/2 or R/3, External System or FastRFC (Default: 3)")] [SAPName("TYPE")] [TypeConverter(typeof(DestinationTypeConverter))] public virtual string Type { get; set; }

So can anyone help me to connect to R/3 with SharpSapRfc ? Great project by the way, it's very hard to find SAP information on the web.

Hi,

Could you try to do the same connection with SAPNCo 3 without SharpSapRfc? I pretty sure this issue is not directly related to SharpSapRfc.

Which version/release your R/3 is running on? The message is not clear, but seems like this is something on your SAP instance.

Yes it's related to the SAPNco 3 that's why I would like to know if there is some way or configuration to connect to SAP R/3. If i'm not wrong the release is 31I .

I can connect using another project that is using the old assembly "SAP.Connector.Rfc" 2.0.0.0 that is targeting .net 1.1 . It also needs librfc32.dll.
The issue here is that the old assembly only compiles in 32 bits.

ptnull,

Have you been able to find a resolution for this issue? My company uses SAP R/3 and has no plans to upgrade but like you I do not want to be stuck with a legacy library with no path to upgrade.

Hello, if I remember correctly I ended up creating a separate project library DLL with this assembly.
My main 64bit project is consuming that when it needs to conect to older versions of SAP.
