entity framework modeling problems

A

alex

We have 2 connected tables with relationship many to 1.
We would like to create an entity on table's many side that also contains
the propertieses of the table with relationship 1
If we try to do it we get the following error

Error 3015: Problem in Mapping Fragments starting at lines 147, 159: Foreign
key constraint

'FK_BancaAnagraficaCAB_BancaAnagraficaABI' from table BancaAnagraficaAgenzia
(idBancaAnagraficaABI) to table BancaAnagraficaABI

(id)::Insufficient mapping: Foreign key must be mapped to some
AssociationSet on the conceptual side.

Can someone give us indications about kindly it?
