I have an ID that is used as the key in many tables.

I want to find all records from one table where there is no corresponding record in another table where both have the same key field.

Sorry for such a simple question.

Have you tried a not equal relationship?

To do this with a simple find, perform a find for the related ID with omit. In a script it would look like this:

Go to Layout [ SomeLayoutBasedOnLocalTable ]

Enter Find Mode []

Set Field [ RelatedTable::PrimaryID ; "*" ]

Omit Record

Perform Find []

Interested in a small consulting arrangement?
