Thanx,
this is what i currenty doing, i just hopped for reference-descriptor in product solution. So i
could get easier the products specials in my
product, as i now that there is only one special
per product.
To use a reference-descriptor in Product (1:1 relation to Special) you need a FK to Special in Product table (special_id).
regards, Armin

well this sounds as Product has a 1:n relation with Special, because Special has an Product FK (product_id) and the Special has an 1:1 relation to Product. The FK 'product_id' have to represent the PK of Product.
So you can declare a collection-descriptor in Product and an reference-descriptor in Special.

thx Claudio
