Can't add or change record.  Referential integrity rules require a related record in table 'Item'.

Error 3201

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 change or insert a record in the "many" table in a one-to-many relationship2ARBGXO, and that record doesn't have a related record in the table on the "one" side.

If you want to add or change the record, first add a record to the "one" table that contains the same value for the matching field.
