I have selected the checkbox "Enable Interaction History" on the "Interaction History" tab of a Import Proposition Data shape in my Strategy. However, I am not able to figure out how to access the Interaction History details in the following shapes.
If I am using a import Interaction History shape, the next shapes have access to all the related properties.
Indeed, see also that post, but specifically: in the proposition import shape you explicitly specify which properties to retrieve. You can, for example, map the retrieved count (how often that proposition was offered to that customer in the last X days) to strategy property.
I believe there are a few properties that are imported implicitly like pyOutcome. But don't pin me down on that and to make things clear, I would just specify the properties I need explicitly.
