That message is coming from the VFP error handler. If you use buffering, you can call TABLEUPDATE() to write the changes to the tables. Then, instead of getting an error message, TABLEUPDATE() will return .F. You can then use AERROR() to see what went wrong. For example, error 1539 is the trigger failed error, so you can check for that and handle it yourself.
