According to section 6.5.2 of the AppDevGuide you are correct, Database 
Configuration Tools (DCTs) are only supposed to present and let users set 
values for fields that have promptgroup() defined.  However the document also 
goes on to say that there are no known tools that actually follow this rule.  
In section 6.5.3 a note under "gui_group" says that many record types haven't 
assigned the right groups to some fields anyway.  As Mark said, the IOC 
currently ignores this rule (but in the future it might enforce it).

Evidently your CapFast conversion tool is following the documented rules, so I 
would encourage Mark to add the above line for the next Asyn release.  Other 
record type authors should also make sure that they are defining promptgroup() 
where appropriate, and DCT authors might want to look at using this to filter 
out the run-time-only fields from those that get presented to the user.

I have a vague recollection that Kay or someone else at SNS actually went 
through and configured the right groups for the Base record types; if those 
changes are still available somewhere they might be suitable to be added to 
the new R3.15 series...
