Formula Variable

Hi Experts,

I like to create one formula variable for 0CREATEDON characterstics for testing purpose. 0CREATEDON is having values in infocube.

I have created one forumla variable with replcement path on 0CREATEDON with date as dimension type. But when i assigned this formula variable to formula directly just to display the values of 0CREATEDON, at run time its giving me vaue as 'X' of all the records.

Where i am missing?

Cheers!!!!!!
