In this case (and this is a guess, assuming you can possibly have more than one document, per supplier) you'd base the Main Form on tblSupplier and the Subform on a Form based on tblDocuments. The tblSupplier would have to have a Primary Key, something like SupplierID, with tblDocuments having that same SupplierID as a Foreign Key. These Fields would then be used to connect the Main Form and Subform via the Subform's Properties Link Master/Link Child Fields.
You can then enter data into both Tables from a single 'form.'
