Can't delete or change record. Since related records exist in table 'Item', referential integrity rules would be violated.

Error 3200

You tried to perform an operation that would have violated referential integrity2T9S4Y 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 relationship2ARBGXO 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.
