WebI Purge Data #error when UserResponse and ToDate function is used in same formula

I have a formula which works well when there is data but when I purge the webi report I get #Error for the cells wherever I have used UserResponse and ToDate function in the same formula.
Ex: =FormatDate(ToDate(UserResponse("Enter Modified Date:");"M/dd/yyyy hh:mm:ss a");"MM/dd/yyyy")
Is this known issue? If anyone knows the solution. Please answer it.
(FYI, I am using BO4.0 SP5)

Hi Naveen,

You can use IsNothing() function to check whether value exist or not.If value is not exist then assign date '1900-01-01'.

=FormatDate(ToDate((IIF(IsNothing(UserResponse("Enter Modified Date:")),'1900-01-01',UserResponse("Enter Modified Date:"));"M/dd/yyyy hh:mm:ss a");"MM/dd/yyyy"))

Open in new window

FYI, WebI doesn't have a function called "IsNothing".
When you purge the data it also purges the response to the prompt thus the error indication.

You can try using the IsPromptAnswered function.

I don't have a WebI environment here but I will check the format in the morning.
