Junk value during date subtraction
I have created two Key Figures with type Date.
And i have created a subtraction formula on them.
I am getting the correct values for the dates that are present.
But for the records for which the date is not present, i m getting a junk value as my answer.
What should be done so as to avoid a junk value to be displayed???.
Please reply ASAP...............Its really urgent.
