This sample shows how to read the user names and address data of all users in the SAP system using the function module BAPI_HELPVALUES_GET.


The following sample code reads user names and address data of SAP users using uses selection parameters for the import Table (SELECTION_FOR_HELPVALUES) of BAPI_HELPVALUES_GET.

static ArrayList getUserList(string sign, string option, string low, string high)
            // Set your ERPConnect license

            // Open the connection to SAP
            using var connection = new R3Connection(
                host: "server.acme.org",
                systemNumber: 00,
                userName: "user",
                password: "passwd",
                language: "EN",
                client: "001")
                Protocol = ClientProtocol.NWRFC,

            RFCFunction func = connection.CreateFunction("BAPI_HELPVALUES_GET");
            func.Exports["OBJTYPE"].ParamValue = "USER";
            func.Exports["METHOD"].ParamValue = "GETDETAIL";
            func.Exports["PARAMETER"].ParamValue = "USERNAME";
            RFCStructure shlp = func.Exports["EXPLICIT_SHLP"].ToStructure();
            shlp["SHLPNAME"] = "USER_ADDR";
            shlp["SHLPTYPE"] = "SH";
            RFCStructure sfh = func.Tables["SELECTION_FOR_HELPVALUES"].AddRow(); ;
            sfh["SELECT_FLD"] = "MC_NAMELAS";
            sfh["SIGN"] = sign;
            sfh["OPTION"] = option;
            sfh["LOW"] = low;
            sfh["HIGH"] = high;
            ArrayList user = new ArrayList();
            for (int i = 0; i < func.Tables["HELPVALUES"].RowCount; i++)
                user.Add(func.Tables["HELPVALUES"].Rows[i, 0]);
            if (user.Count == 0)
                user.Add("No results matching criteria");
            return user;                           

How to display all users, whose name start with M:

static void Main(string[] args)
            ArrayList users = getUserList("I","CP","M*","");
            foreach (object userdetail in users)
