-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Windows, version 3.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

After running the Referential Integrity (RI) Builder and selecting Cascade in
the "Rules for Deleting" tab, you may receive a 'Trigger Failed' error message
when you attempt to delete a record.

CAUSE
=====

The current Visual FoxPro configuration has dBASE Compatibility set to ON.

RESOLUTION
==========

Compatibility must be set OFF for the deletes to work with the RI Builder. You
can either type SET COMPATIBILITY OFF in the Command window, or you can click
Options on the Tools menu, click the General tab in the Options dialog box, and
clear the dBase Compatibility check box.

There is currently no way to have dBASE compatibility ON and make deletes with
referential integrity.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article. This problem was corrected in Visual FoxPro 3.0b
for Windows.
