With RFC (and SharpSapRfc) you don't use transactions, only Function Modules like BAPI or Z's. You can try using BAPI_PO_GETDETAIL1 to get details from a specific PO.

The code should be something like this.

using (SapRfcConnection conn = new PlainSapRfcConnection("SAP"))
{
    var result = conn.ExecuteFunction("BAPI_PO_GETDETAIL1", new
    {
        purchaseorder = "4500425010"
    });
    var header = result.GetOutput<POHeader>("POHEADER");
    var itens = result.GetTable<POItem>("POITEM");
    //...
}

Thanks for the response :+1: , but if I am outside the LAN/intranet, and accessing via internet,

1. then should I use SOAP or webservices.
2. besides putting the credentials, do I need to ask SAP to configure a channel or will this information be available from the object calls in the lib?
3. how can I get a table of all PO's open and their details?
4. In the build of the solution its looking for some dll's SAP middleware name spaces, is this dll from Nuget or somewhere here, I did not see an internal build dependency for this dll.

thanks

1) Yes, you should use SharpSapRfc.Soap when connection to SAP from outside your private network. 2) Your SAP need to be reachable from the internet, either directly or behind a Reverse Proxy (like SAP WebDispatcher). You can try it directly from the browser with the following URL:

http://<your-sap-address>:<your-port>/sap/bc/soap/rfc?sap-client=100

It if works from the browser, it will surely work with the library.

3) I'm not a MM specialist, so I don't know any existing BAPI for that. If there is none, you can always write your own Z function module.

4) The only project with SAP Middleware dependency is SharpSapRfc.Plain.x64 and x86, because it uses SAP NCo internally. But in your case you can go with Soap without any external dependency.

Hi, can you suggest, where would I find the PO tables list (I am not a partner) or is the table you gave me maybe/closeto the correct one Do I need to change the object SapRfcConnection to the SapSoapConnection?

[goenning]

It's easy to find it in Google. This is a good start: https://scn.sap.com/thread/777633

And yes, you need to chage the connection class, but it is SoapSapRfcConnection.
