>>>Hi All,
>>>
>>>My problem is, when I add a new person to my Parent table I also need to add theit Social Security number to about 8 other tables (SSAN is a candidate key). I don't know how to go about creating a custom procedure and modify my referential integrity. Is there anybody out there who have these same requirements and how did you go about accomplishing the task. Using VFP 5.0.

>>>Thanks in advance

>>Are you using SSN as a key????? YIKES!!!! SSN is NOT unique. There are duplicates. I went to college with two people that had the same SSN. Talk about a nightmare.

>They should be unique identifiers for U.S. citizens, but due to fraud/error it's possible to have trouble, as you say...

It's not just fraud. Error is the main problem. The government has issued duplicate SSNs.
