RE: Calculate the 20th of next month

["Rex Capio" <rex_capio@xxxxxxxxxxxxxxxxxxxxx>]

Can't do....

e.g.  Base Date = 12/31/2009

Extracted Day = 31;

Subtract 31 from 12/31/2009 = 11/30/2009;
Add 1 month to 11/30/2009 = 12/30/2009

Add 20 days to 12/30/2009 = 1/19/2009,

How about you extract the days from your base date field (EXTRCT). Then 
subtract (SUBDUR) that amout from the date.  Add one month(ADDDUR) to 
the result then add 20 days to that result.
