@vlruch67 Are you looking for a change of display format for the dates in Paxata? If yes, we always display the formats in the way @ebarre's comment above shows it. If you want to view it in a different format like yyyy/mm/dd you can do certain other computed columns like:
concatenate(year(@date_column@), "/", month(@date_column@), "/", day(@date_column@))
Please let us know if this is what you're looking for. We can discuss this in detail if needed.
