Reproducing the Issue

  1. Create a Crystal Report against the Xtreme Sample Database
  2. Create a new formula (Field Explorer ->Right click ‘Formula fields’ ->New) as follows: 

          tonumber({Orders.Order Date})

        3.   When you try to save this formula it throws an error : ‘There is an error in this formula: A string is required here’


    1. Edit the same formula created above as follows:
    2. stringVar yyyy;
      stringVar mm;
      stringVar dd;
      numberVar result;

      if result=0 then
      yyyy:=replace(replace(cstr(year({Orders.Order Date})),",",""),".00","");
      mm:=replace(cstr(month({Orders.Order Date})),".00","");
      if len(mm)<2 then mm:="0" & mm;
      dd:=replace(cstr(day({Orders.Order Date})),".00","");
      if len(dd)<2 then dd:="0" & dd;

      result := ToNumber(yyyy & mm & dd);

    3. Save this formula and you can now use the variable ‘result’ in any other formula which requires date manipulations
