In the July release we got the option to rename fields per visual (which is really great!!) :
However, when using a SSAS Tabular live connection, the rename option doesn't appear when the field is a in a hierarchy:
I can repro the same issue as you. I’ve reported it internally to Power BI Team: CRI 42023525I’ll post here once I get any update about it.
I’ve got response from the Product Team.
By design, we do not support rename for hierarchies.
I hope this issue doesn't fall off the radar now that it has been closed.
Are you sure the team understood you correctly? I'm not saying I want to rename the hierarchy, just the columnname. Just because it happens to be in a hierarchy shouldn't mean we can't rename it imho.
If it's really "by design" than I would love to know why it was designed that way :-)
And whether it's on the roadmap to be implemented at a future date.
I'd like this too. I can rename the column if I use it in isolation. But not if I use it in a hierarchy - which means mmy column headers in my drill are meaningless
