Unfortunately no. One dimension can only have one alias which cannot be repeated with other aliases.
But you can add space and it seems like they're the same.
When you put them in the dashboard with highlight function, different dimensions can't be highlighted.
Thank you Tian!
I discovered that what we can do is: create duplicate of a column (which displays the dimension) in one worksheet, and I was able to set assign different alias to this dimension. Then I hid one of the column.
You can create duplicate of the dimension and use that in other worksheet.
great! thanks for sharing.
