I am struggling with this issue since few days. I don't know how i can change the field name of one column in the extract file i get from my colleague. I want to rename it and save as a new .hyper file, but adter i did this, the filed name in the new extract is still not updated.
My colleague is on leave, so he cannot help me to change in original excel file to make a new extract. It would be great if someone could help me on this.
Maybe I'm missing something, why does the rename not work? Are you trying to change the field name in the navigation window (like this screenprint), or the underlying remote column name (which you can see if you go to Describe...)
