This is one of the design differences between Paradox/DOS and PFW and stems 
primarily from IDAPI's ability to enforce validity checks throughout all the 
uses of a table (Table window, TCursor edit, form, etc.) whereas PXD could 
only enforce RI at the form or individual field level.
If you have a required field, you must place a value in that field when using 
it from PFW whether or not you enter it.  No correction possible; it's the 
way things are designed to behave.  If it causes a some problems, I'd suggest 
against using required fields.  (I haven't found a compelling need for one in 
the last three years; there's a number of other ways of making sure the field 
isn't empty.)
 
Hope this helps...
