I don't know - what kind of lookupcombo controls are they?
If ib_lookupcombo, are their datasets set up properly for updating
(KeySource, KeyLinks)?

Are the polling columns updatable? ---- Just looked back at your query, and
the Description column isn't updatable:

Select
(Select ProgramDescription
from HBProgram
where CP.ProgramID = HBProgram.ProgramID) as ProgramDescription
, (select (Select FULLNAME FROM FORMATNAME(
person.firstname,
person.middlename,
person.lastname, 'LNF'))
from CASEMANAGER join Person P on CaseManager.PersonID =
P.PersonID
where CP.CaseManagerID = CaseManager.CaseManagerID) as
CounselorName
, CP.IsPrimary
, CP.DATESTARTED
. . . (many other fields ommitted)
FROM CASEPROGRAM CP
where CP.CaseID = :CaseID

So, the answer is, if you have lookupcombos linked to non-updatable fields,
not lookupcombos nor anything else (e.g. direct assignment) will make them
updatable. Subselected output values are *never* updatable; and, in a
joined set, you can update fields in one table AT MOST (as long as that
table is named as the KeyRelation) and then *only* database columns. The
way to make more than one table updatable is to write a stored procedure to
do it, and pass the keys of the involved tables to it as input parameters.

Sorry for not noticing that first time around.

Go back to the write-up on lookupcombos, and you will see that the linkage
is made from the primary key equivalent of the lookup set, back to a
polling key in the parent set.
