Invalid entry. Cannot perform cascading operation in table <name> because the value entered is too large for field <name>. (Error 3411)

You are trying to save a value to a primary key field that is included in a relationship.

In Microsoftｮ Access, the Cascade Update Related Fields option is selected for the relationship; or, in DAO code, the dbRelationUpdateCascade option is specified for the Relation object's Attributes property. Setting either one of these options will cause your application to attempt to update the matching field in the related table.

To save your changes to this field, the text you enter must be no longer than the field size of the related field that your application is trying to update for you. In this case, the related field has a shorter field size than the field you are updating. To avoid this problem in the future, set the Size property for both of the matching fields to the same value.
