I have two business objects, LocationsBO and CreditMemosBO. I fill the LocationsBO by a permission key. If the permission is deny I remove the row from the current datatable. Once this LocationsBO is filled, I have all the locations a user has access to. What I want to do is to be able to fill the CreditMemosBO by the LocationIDs that are in the LocationsBO (CreditMemosBO has a foreign key LocationID). I was thinking of using this:





but it doesn't work. Is there a better way of filling a second BO based on permissions of a different BO? I could put a permission key in the CreditMemosBO but I don't want the extra overhead of inserting a permission key when a record is added.
