Read new interaction property via strategy

Hi guys,
Due some business needs I need to create a new Interaction Property. I did by adding a column in Interactions (IXN) table and associating a Business Attribute on UCS to Interaction (UCS) table.
So now when customer calls I go to a WebService and returns a value. I save this value on these tables. So far so good. Email scenario here.

Idea is now that this in an Interaction attribute I need to, when customer sends an email following the initial email thread (customer, agent and now customer again) I identify initial custom attribute as it is saved on the tables. I can see that effectily UCS keeps the same attached data without new intervention on my strategy. Now I need to retrieve this value from the UCS table…any clue how to do this? Can’t find on IRD any object to get Interaction properties.

Thanks!

Forget this…View condition property is what I was not looking at and need…
