How can I enforce referential integrity on a InfoPath2k3 Form? Bidyut Bhattacharjee 04.08.2006 11:48:02 I have two access tables a master and a detail table. The master has a primary key field and the details has a secondary key field (one to many relation). I am using a InfoPath 2003 form for data entry into the details table. The Infopath form won't allow two key fields (one compulsory unique key and the other is the secondary field of the details table) and does not allow the user to submit the form.
