MORE INFORMATION

When you enter a value in the foreign key field of an AutoLookup query, fields from the "one" side table should update automatically with related information. However, if you are adding a new record and one or more fields from the "one" side have a default value, Microsoft Access assumes that you are trying to add a record to the "one" side as well as to the "many" side.

If there are no default values for any of the "many" side fields, when you enter a value in the foreign key field after making an entry in another field from the "many" side table, you receive the error message:

If there are default values for any of the "many" side fields, or if you have not entered any value in any field from the "many" side table, you will receive the following warning message in the status bar after you enter a value in the foreign key field:
