Referential integrity enforcement via linked table

I am placing a relationship between "tblpaymentsreceived" and another table linked from another Access database that includes a joining reference field.

I reconciled both tables to ensure that data in the joining field was reflected in both tables and linked them.

A "One-to-Many" relationship was highlighted in the dialog box but I cannot check the "Enforce Referential Integrity" box.  I have tried inputting an incorrect reference number in "tblpaymentsreceived" and no error message appeared.

Can I not enforce this referential integrity rule because of the linked table?  If so, how can I discipline input (can I place a combo box in the "tblpaymentsreceived" field that only reflects reference numbers from the linked table)?

Hello MidlandR,

Referential integrity must be enforced in the database where the tables are held (that is - the backend database)

no, you cannot apply REFERENTIAL integrity rules on LINKED tables.  The rules MUST be established on the Actual Physical tables, themselves.


As for using a Combobox based on the Linked table, to enforce the relationship in code, that is the proper solution fopr this problem.

As stated above, this isn't possible.

You basically have two options:
1) Move "tblpaymentsreceived" to the other database
2) "Force" the referential integrety from your application, however when the user(s) have access to the tables, this can fail :-)
