but when I open Contributor I see a cell Simple type

How I can to see peaklist Calendar in a Contributor?
What excatly do you mean by "cell Date type"? There are only 3 cell "types" simple, string or Consolidated.I have a cube with a cell Date type in Performance Modeler when I want enter data I see picklist Calendar
Ah ok, you mean the formatting of the attribute, got ya.I have dimension with Date Format type
I could not see the images in your post but now I understand what you mean.I don't have picklist syntax You can see it in the last image. I get a drop-down calendar in Performance Modeler by default
It all makes sense now, thanks.That drop-down calendar feature only works in Performance Modeler. Once you access your cube with regular TM1 then it doesn't exist.
