Hello, @BenjaminSarkisyan
In short: yes, it is possible.
All you need to do is: add relationship to the entity mapping. In entity mapping you should have only one Attribute Mapping for PK property and no key path.

Sure:

FEMManagedObjectMapping *userMapping = [FEMManagedObjectMapping mappingForEntityName:@"User"];
[userMapping setPrimaryKey:@"userID"];
[userMapping addAttributeWithProperty:@"userID" keyPath:@"userID"];

FEMManagedObjectMapping *cityMapping = [FEMManagedObjectMapping mappingForEntityName:@"City"];
[cityMapping setPrimaryKey:@"cityID"];
[cityMapping addAttributeWithProperty:@"cityID" keyPath:nil];

[userMapping addRelationshipMapping:cityMapping forProperty:@"city" keyPath:@"cityID"];
