Delphi Rave Report generating blank page

Question

I have some experience with Rave Reports 10 i've made lot of reports in the past, but now im having a issue with generation of it.

Checklist: On main form -RvProject -RvSystem -RvDataSet -RvRenderPDF

All of them set up

On Rave designer i can generate the report sucessfully but when i use the code it generate a blank page.

Can you check my code and tell me if im missing something please? Im stucked at this steep since two days ago, and cant solve this issue.

I know there is a lot of variables without use, but im trying some things.

procedure TFormPrincipal.ImprimirReporteDeNomina(FechaCorte:String);
var
  DireccionMisDocumentos,A:String;
  Año, Mes, Dia:Word;

  myPage:TRavePage;
  MyDataText:TRaveDataText;
  MyText:TRaveText;
  //MyPage2:TRavePage;
  nMarginBottom, nMarginLeft, nMarginRight, nMarginTop: Double;
begin
  with RvProject1 do

      SetLength(FechaCorte,10);

I finally found the error, was a writing mistake

The error was: RvSystem1.Execute;

The correct way is: RvProject1.Execute;

Its solved
