I'm trying to alias a boolean (T/F) dimension with two values: t = "Pass" and f = "Fail" -- consistent with the best practices described here: Editing boolean aliases. However, for complicated reasons I'm changing the default data type to a string (I need to use it in a calculated field with an If/Else statement that also takes in a string). When I go to publish the workbook, the aliases for this boolean-as-string are getting reset to t and f.

I'm using Desktop 9.0. Is this a known issue?
