Hi Claudio, Depends on the extension scope I guess. JavaScript code copy pasted inside extensions and scoped to all tags / specific tags are by default wrapped in an anonymous function scope, i.e. not possible to trigger them without calling utag.view / link. However, if you define your in page data layer modification functions in a pre-loader / dom ready scope, and make them referenceable (named functions) then you can trigger them at will. I assume you are planning on overloading an in page function? If you really want to take the creative hat on, you could try run all tags scoped extensions (your lookup table extension) without firing tags, by passing in a dummy value to utag.track directly: utag.track("claudio", { "data_source_name_trigger" : "new value to consider" }); By calling utag.track with a custom value as first argument, no Tealium IQ tag templates will know about "claudio" event, unless you have explicitly modified a profile template to react to the "claudio" event type. Not knowing your exact challenge you are dealing with here, but perhaps your day-to-day SE can help you with iterating over it with you. Please note that extensions are designed to run in conjunction with what is supposed to be considered a page view and / or click data ultimately triggering tag technologies to fire.
