Build an RFC Client with NCo 3. VB. NET A Step By Step Guide. Recently, I published an article showing step by step instructions for how to consume an SAP RFC with the SAP. Net Connector 3. 0 NCo 3. The article included code samples and a working code example for download written in C. Well, not everybody writes in C. There are some of you that would prefer to write in VB. NET.  So, I have heeded your call, all you VB. NET developers  Here is your very own article detailing how to build an RFC client with NCo 3. VB. NET. The SAP. Net Connector 3. 0 NCo 3. SAP. NET Connector 2. Unfortunately, SAP no longer offers example. NET code.  This blog attempts to fill that gap by describing how to build a simple RFC Client using SAP. Net Connector NCo 3. VB.

JCO_RFC_PROVIDER%20NWA.png' alt='Sap Program To Test Rfc Connection' title='Sap Program To Test Rfc Connection' />OSS login required. Setting up the Project. Using Visual Studio 2. Windows Form project. In the project properties, be sure to set the Target Framework to. Net Framework 4. 0. To change the target. NET framework version on a VB. NET project, first open the projects property page. Click on the Compile tab in the property page. Then click on the Advanced Compile Options. In the ensuing dialog window, change the target framework version. Next, add references to the SAP. Net Connector 3. 0. There are two DLLs, sapnco. Design the Form. Add two controls to the form.

Within the destination, the Name field identifies this app. Sap Program To Test Rfc Connection' title='Sap Program To Test Rfc Connection' />Specify the appropriate user name, password, SAP host name, client and system number in the destination section. The BAPIs. Use the SAP transaction SE3. BAPICOMPANYGETLIST and BAPICOMPANYGETDETAIL. Do you know how to check if your SAP Landscape is ready for SAP Fiori ImplementationDo you know how to Activate the SAP Netweaver Gateway ServiceWhy do we. This will tell us what parameters need to be passed in and where to find the results that are returned to our code. The Code. During the form load event, we want to populate our List Box with the defined companies from SAP. Acquire a valid Rfc. Destination to use. Use method Rfc. Destination. Manager. Get. Destination to do this. Get. Destination requires a parameter to determine which SAP host to refer to. Pass in the Name of the SAP host you previously defined in the app. Hi, Have you seen SAP note 839020 Also make sure you have the latest available Kernel installed on your SAP Servers. Regards.

Destination object. Line 4. 2Using the Rfc.

Net Connector 3. 0 NCo 3. The article included code. One of the more common challenges related to the SAP NetWeaver BW Accelerator that SAP administrators face is a broken RFC connection between the blades of the BW. Note. CloudOnly deployment in this document is defined as complete SAP landscapes are running exclusively in Azure without extension of Active Directory OpenLDAP. Below is SAP Profile Parameters list with default values and short description. The SAP Profile parameters plays an important role in several areas. Secure Network Connection SNC is the SAP technology provided for Network and Transport Layer Security. In this. Repository object, acquire a reference to the SAP BAPI by calling method Rfc. Repository. Create. Function method. Pass in the name of the desired function as a string parameter to Create. Function. This method returns an object we can use to setup parameters, invoke the function, and retrieve results. Now we can make the RFC calls into SAP. Using the IRfc. Function object returned by Create. Sap Program To Test Rfc Connection' title='Sap Program To Test Rfc Connection' />Function, call the Invoke method, passing in our Rfc. Destination object as parameter. This will make the RFC call into SAP, and provides the results via our IRfc. Function object. Line 4. SAP function BAPIGETCOMPANYLIST returns a table of company records. We use an instance of an IRfc. Table object that we retrieve by calling the Get. Table method on the IRfc. Function object. To get a desired table, pass in the table name to the Get. Table method. Line 5. We now have an instance of an IRfc. Table object that contains company information through which we can iterate. It is possible to iterate through the data by setting the Current. Index property on the returned table. For a particular row in the table, it is possible to access values using the Get. String method. Lines 5. For each company, get the Company. Number, and use that as a parameter to SAP function BAPICOMPANYGETDETAIL. BAPICOMPANYGETDETAIL returns detailed information about that particular SAP company. The techniques are the same as before, with the additional step of using the Set. Value method on the IRfc. Function object to pass in the company number as a parameter. Lines 6. 0 6. 7BAPICOMPANYGETDETAIL returns data as an instance of the IRfc. Structure interface. Access individual field data of the company record, using the Get. String method of the IRfc. Structure object instance. Lines 6. 7 7. 8Extract the company details as desired. Add them to some object you create and then add that object to the List Box control. Line 8. 0The rest of the code is regular Windows Forms programming. Your code will need to wire up the List Box changed events so that the Property Grid will display the details of the selected company. Additional Information.
