I got to know that in version 9.1 Alteryx will have Unique Tool with "Unknow"check box to make it dynamic. I want to suggest same logic for Summarize tool for making it Dynamic. Please add Unknow like functionallity in Summarize Tool
This really needs to happen. We have data that change, and we'll miss new fields or ones that dropped out because of threshold constraints in previous runs. Having to run huge datasets through multiple times before we catch all of them when we have hundreds of fields to summarize is not pleasant or sustainable.
