set analysis date

[rolandg1881]

Hi!

Following question:

I have this formula

sum(
{< Cust_number = {'70407'},[CLM_Type]={'claim'} >}
[CLM_PickupTime])
/
sum(
{< Cust_number = {'70407'},[CLM_Type]={'claim'} >}
[CLM_Counter])

Then i have the value CLM_Date (MMM-YY example May 21)  and i want to see the result from the formula where the date is bigger then May 21. 

But i dont know which syntax i have to use in the formula for this date expression...

Thank you for answers.

Greetings Roland
