Hello Friends,
    I am trying to add Sales Opportunity using DI API.I want to set Potential amount using DI API So I set MaxLocalTotal but while compiling code its give error.Its Read only.
If I add without potential amount than its gives me error  "Potetial Amout is missing"
What should I do??
My Code is

                vSOpp = (SAPbobsCOM.SalesOpportunities)globals1.oCompany.GetBusinessObject  (SAPbobsCOM.BoObjectTypes.oSalesOpportunities);
                vSOpp.CardCode = txtBPCode.Text;
                if( txtCntctPerCode.Value!="")
                vSOpp.ContactPerson = Convert.ToInt32(txtCntctPerCode.Value);
                vSOpp.OpportunityName = txtOppName.Text;
                vSOpp.SalesPerson = Convert.ToInt32(ddlSEmp.SelectedValue);
               //vSOpp.WeightedSumLC = Convert.ToDouble(txtPotAmt.Text);
                vSOpp.MaxLocalTotal = Convert.ToDouble(txtPotAmt.Text);       
               culture = new CultureInfo("en-US", true);
                currentprovider = CultureInfo.CurrentCulture;
                dt1 = DateTime.ParseExact(txtSDate.Text, "dd/MM/yyyy", culture);
                vSOpp.StartDate = dt1;
  if (vSOpp.Add() != 0)
                    //ResultMessage1.ShowFail("Failed to add a Activity");
                    globals1.oCompany.GetLastError(out nErr, out errMsg);
                    if (0 != nErr)
                        ResultMessage1.ShowFail(globals1.oCompany.GetLastErrorDescription());
                        globals1.oCompany.Disconnect();
                        return;
                else
                    ResultMessage1.ShowSuccess("Activity added Successfully");
Please help me to solved this problem.

Hi folks,
I'm facing the same problem. This issue concerns DI API of SAP Business One 8.8 (my version is SP 00 PL 11) in particular.
I've used the 2007 version so far and even though the MaxLocalTotal field in Sales Opportunity object is read-only, by writing the same value in the field with the same name on the last Opportunity Line I obtain the right value in the header.
In this version of the API, that field seems to be mandatory instead.
Does anyone have any suggestion? Thank you in advance.
