Yes, you are correct. I am reading the VFP help and that the Persistent relationship has to be established.

But let me, if you don't mind, as you another question. Do I understand correctly that after I build the persistent relationship and build the RI the code in the database will be something like this (pseudo code):
Use Table1
update Table1 set FieldA = cSomeValue where FieldA = cOldValue
and son on for other tables?

I am just trying to have a sneak preview of what the resulting code will look like.

Thank you.
