Hello Alteryx-Community, 
I want just to concatenate ALL fields from a "Optional Incoming Connection"-Input without GroupBy. Showing Field Map is not necessary. The number of fields and their names can vary. But the type and comma-seperator will be for all fields the same. The type of all fields is V_WString. First I tried it with "Select->All" in the Summarize-Tool. But it didn't save this configuration for other vary incoming connections. So i want to try update Raw XML, but I'm not familiar with it and my first try was with inspiration from another topic. Unfortunately it does not work. I appreciate any help!
Thanks and greetings
