I want to add a conditional rule to protect Product business object from changes by some categories of users. I want to protect Product if this Product was ordered before. When a product is ordered, it is linked to OrderItem business object by Product.ProductOrdered attribute. I tried to add this rule to the Product

If OLD_VALUE(Product.ProductOrdered) IS DEFINED
Then PROTECT Product FROM ALL EXCEPT Administrator AND Manager

However the system did not accept IS DEFINED with OLD_VALUE, is it what supposed to be? Can you suggest another way to protect Product?

Thank you.

I am using AwareIM version 1.3 build 693

The work around is to always initialise ProductOrdered to 'No' to make sure that this value is always defined. Then define the following protection rule:

If OLD_VALUE (Product.ProductOrdered = 'Yes') Then
PROTECT Product FROM ALL Except Administrator AND Manager
