I have some doubts related to using variables inside delivery activity. I know how to do it using Enrichment and <%= targetData.foo %> in delivery. But I have some questions about other methods:
2) I have tried set up variable in Delivery/Properties/Variables. I used $(instance/vars/@foo) as an expression. But delivery failed again (error: "Unable to parse expression '$([instance/vars/foo])'. XTK-170018 Parameter of query '[instance/vars/foo]' is not defined in current context."). Any Idea why?
3) How can I assign instance.vars.foo to the variable in Delivery/Properties/Variables? I'm using Recurring delivery, so there is no Initialization Script tab in Properties.
