>Hmmm... if you delete the generated code then you'll also be deleting the code that cascades the deletes to the child. If you're not happy with VFP's RI code engine, you might want to consider using a CASE tool for your database. I can recommend xCase (www.xcase.com), it allows you to define code templates for RI generation.

I used Walter's class from Download section and everything appears to work correctly, but I didn't understand the generated code. Anyway, I'll study it later...
