Error 2062: no mapping between entity set and association set

Question

Are entities required to be mapped to a table or can they map to a stored procedure?

I have an entity that does not map to any specific table, instead it maps to a stored procedure.

I am getting the following error:

Schema specified is not valid. Errors: Model.msl(6,6) : error 2062: No mapping specified for instances of the EntitySet and AssociationSet in the EntityContainer HNFS_ProviderEntities.

Answer 1

It appears to be yes: http://msdn.microsoft.com/en-us/library/bb896279.aspx

It turns out that instead of an entity I needed to use a complex type.
