----------------------------------------------------------------------------------------------------------------------------------------------------

Commonly we only OnOpen, OnBeforeSave & OnGridColumnValueChanged Event

----------------------------------------------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------------------------------------------

Avoid use 2 same Event/Action in 1 Business Object (eg 2 OnOpen in Sales Invoice is NOT allow)

----------------------------------------------------------------------------------------------------------------------------------------------------

function ComServer: Variant;
begin
  if FComServer = Null then begin
    FComServer := CreateOleObject('SQLAcc.BizApp');

    cdsData.Data := ComServer.DBManager.Execute(lSQL);
  finally
    lBizObj    := null;
    FComServer := null;
  end;
end;

begin
  if SameText(EditingField, 'ItemCode') OR // when selecting or change itemcode field
     SameText(EditingField, 'UDF_Rate') then begin // when change UDF_Rate field
    try
      GetStockInfo; // Get UDF_Length & UDF_Width from Maintain Item

      // Below is Set the Invoice detial UDF Fields from Maintain Item UDF Fields
      DataSet.FindField('UDF_Length').AsFloat := cdsData.FindField('UDF_Length').AsFloat;
      DataSet.FindField('UDF_Width').AsFloat  := cdsData.FindField('UDF_Width').AsFloat;

      // Below is doing calculation for Qty := UDF_Length * UDF_Width * UDF_Rate
      DataSet.FindField('Qty').AsFloat        := DataSet.FindField('UDF_Length').AsFloat *
                                                 DataSet.FindField('UDF_Width').AsFloat *

    end;
  end;
end.
