I'm using .NET Connector calling Rfc_Call_Transaction funtion throught a proxy, i stablished all the params as you can see in the code below, but i get the message cited in the subject 'Start screen does not exist in batch input data'.
What do you think is happening? or Where can i get the samples needed for perform this type of request?
        private BDCDATA FillBDCDATA(string Program,
                                    string Dynbegin,
                                    string Dynpro,
                                    string Fnam,
                                    string Fval)
            BDCDATA st_DATA = new BDCDATA();
            st_DATA.Program = Program;
            st_DATA.Dynbegin = Dynbegin;
            st_DATA.Dynpro = Dynpro;
            st_DATA.Fnam = Fnam;
            st_DATA.Fval = Fval;
            return st_DATA;
        private void button3_Click(object sender, System.EventArgs e)
            SAPProxy proxy = null;
            try
                proxy = new SAPProxy("ASHOST="  + txtHost.Text +
                    " SYSNR="  + txtSysnr.Text +
                    " CLIENT=" + txtMand.Text +
                    " LANG="   + txtLang.Text +
                    " USER="   + txtUser.Text +
                    " PASSWD=" + txtPass.Text);
            catch(Exception excpt)
                txtMsg.Text = excpt.Message;
            if (proxy == null)
                return;
            BDCDATATable tblBDCDATA = new BDCDATATable();
            MESSAGEINF infMessage = new MESSAGEINF();
            //BDCDATA st_DATA = new BDCDATA();
            tblBDCDATA.Add(FillBDCDATA("SAPMKBUA", "0111", "0111", "BDC_OKCODE", "/00"));
            tblBDCDATA.Add(FillBDCDATA("SAPMKBUA", "0111", "0111", "BPDY-BLDAT", "30.12.2004"));
            tblBDCDATA.Add(FillBDCDATA("SAPMKBUA", "0111", "0111", "BPDY-VERSN", "0"));
            tblBDCDATA.Add(FillBDCDATA("SAPMKBUA", "0111", "0111", "FMPS-FIKRS", "ente"));
            tblBDCDATA.Add(FillBDCDATA("SAPMKBUA", "0111", "0111", "BPDY-JAHR",  "2005"));
            proxy.Rfc_Call_Transaction("FM9J","", out infMessage, ref tblBDCDATA);
            txtMsg.Text = infMessage.Msgtx;

Jose,
I imagine you are passing, for the Dynbegin parameter of the private method FillBDCDATA, invalid values.
Why don't you try this way:
tblBDCDATA.Add(FillBDCDATA("SAPMKBUA", "X", "0111", " "," "));
tblBDCDATA.Add(FillBDCDATA(" ", " ", " ", "BDC_OKCODE", "/00"));
tblBDCDATA.Add(FillBDCDATA(" ", " ", " ", "BPDY-BLDAT", "30.12.2004"));
tblBDCDATA.Add(FillBDCDATA(" ", " ", " ", "BPDY-VERSN", "0"));
tblBDCDATA.Add(FillBDCDATA(" ", " ", " ", "FMPS-FIKRS", "ente"));
tblBDCDATA.Add(FillBDCDATA(" ", " ", " ", "BPDY-JAHR", "2005"));
I hope I could help you.
