The record cannot be deleted or changed because table <name> includes related records. (Error 3200)

You tried to perform an operation that would have violated referential integrity rules for related tables. For example, this error occurs if you try to delete or change a record in the "one" table in a one-to-many relationship when there are related records in the "many" table.

If you want to delete or change the record, first delete the related records from the "many" table.
