Date Field Greater than today?

Question

Ok, i've been trying to figure out how to compare a date to today.  Basically i have a field which is a Valid To field.  I want to know if this is still valid by comparing it to todays date.
The idea is fairly simple.  However, it seems that comparing dates is beyond the normal query capabilities for some reason?
So i did some digging around, looking at what other people have tried.
I ended up creating a customer exit variable with the following code:
WHEN 'ZVAR_WHATEVERJUSTWORK'.
      CLEAR l_s_range.
      L_S_RANGE-SIGN    = 'I'.
      L_S_RANGE-OPT     = 'GE'.
      L_S_RANGE-LOW     = SY-DATUM.
      append L_S_RANGE to E_T_RANGE.
When i set up the variable in Bex Query Designer, i call it ZVAR_WHATEVERJUSTWORK (technical).
I set it to be a customer exit, however in the Details tab, i'm not sure what the variable represents.  i've tried single value (query short dumps) and i've tried Interval (query short dumps).  When i'm testing it, i'm restricting a DAT object to my variable.
Quite frankly, i'm amazed something so simple is as complex to set up?  I honestly believe i'm making some mistake somewhere and theres really an easy way to go. 
So i'm asking the powers that exist in the SDN forums.
Any ideas?  what am i doing wrong? Please help
If i've not provided enough info, please ask.

Bryan,
you can do it this way....
In your query you can have
Valid To Date|Formula Variable 1 | Formula Variable 2 | Formula 3
Formula Variable 1 - replacement path Valid To Date - dimension should be Time
Formula Variable 2 - Customer Exit - Sy Datum
write the exit as
WHEN 'ZVAR_WHATEVERJUSTWORK'.
      CLEAR l_s_range.
      L_S_RANGE-SIGN    = 'I'.
      L_S_RANGE-OPT     = 'EQ'.
      L_S_RANGE-LOW     = SY-DATUM.
      append L_S_RANGE to E_T_RANGE.
Formula 3 - difference between 1 and 2
here in the query you can put a condition on Formula 3 to get the desired result.
