Performing Script Calculation

Below is Example are doing following actions

• Get UDF_Length & UDF_Width from Maintain Item UDF Fields
• Do Calculation Qty := UDF_Length * UDF_Width * UDF_Rate

01. Right Click the Sales Invoice

02. Select New Event

03. Enter any name (eg Calc) in the Name field (Only Alphanumeric & no spacing)

04. Select OnGridColumnValueChanged for Event field

05. Click OK

06. Click the Calc (name create at Step 3 above) on the left panel

var FComServer, lBizObj : Variant;
    cdsData : TClientDataSet;

function ComServer: Variant;
begin
  if FComServer = Null then begin
    FComServer := CreateOleObject('SQLAcc.BizApp');
  end;
  Result := FComServer;
end;
procedure GetStockInfo;
var lSQL, lCode  : String;
begin
  FComServer := null;
  cdsData    := TClientDataSet.Create(nil);
  try
    lCode := Dataset.FindField('ItemCode').AsString;    
    lSQL  := Format('SELECT UDF_Length, UDF_Width FROM ST_ITEM WHERE Code=%s',[QuotedStr(lCode)]);

    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; 
      DataSet.FindField('UDF_Length').AsFloat := cdsData.FindField('UDF_Length').AsFloat;
      DataSet.FindField('UDF_Width').AsFloat  := cdsData.FindField('UDF_Width').AsFloat;
      DataSet.FindField('Qty').AsFloat        := DataSet.FindField('UDF_Length').AsFloat *
                                                 DataSet.FindField('UDF_Width').AsFloat *
                                                 DataSet.FindField('UDF_Rate').AsFloat;
    finally
      cdsData.Free;
    end;
  end;
end.
