Active record code referential constraint.

Suppose you have the following table:
Field Start End Attrib Text
IID 1 2 A2 Record ID; IM/IZ
IPROD 3 17 A15 Item Number
...
Is there a way to build a constraint so that no new rows can be added to a
child table of this table if the parent row is an 'IZ'? Only if it is an
'IM'?

Let's say you have an item master with those columns. I want it so that
if IID <>'IM' that you cannot use that item on a new row in the order line
file.

Am I stuck with a trigger?
