Yes.  I have no idea how many child tables you have, so I don't know the amount of work required to create a view for each one.  You were talking about changing the relationship on each child table; how much work is that?

As for changing the table references, you could rename the old references, then create the views with the same name as the original table reference.

Hi Justin,

I'm not sure what you mean by "get this to work".

If a part becomes obsolete, I would think that you want to keep it on
the PART_MASTER file, but not have it show up in PROMOTIONS, etc.
Wouldn't a view handle that?

Well, if I focus on the "I need the relationships to
be(PART_MASTER.PART_NO = PROMOTIONS.PART_NO and PART_MASTER.OBSOLETE =
'0')" then you could add a field to PROMOTIONS that is defined like the
OBSOLETE flag in PART_MASTER, but always has a constant value of '0'.?
Then the relationship would be

PART_MASTER.PART_NO = PROMOTIONS.PART_NO and PART_MASTER.OBSOLETE =
PROMOTIIONS.OBSOLETE

Of course that's a lot of tables that need to be changed, but perhaps
it's a simpler change than adding a trigger program.
