Creating an axis set allows you to easily create a reusable member list.
To do this, right-click on a column or row dimension label and pick Axis > Create Named Set.
You will be prompted for a name and whether to use a fixed member list. The difference between using a fixed list and not is:
- Standard: Member selections are preserved, so a top 10 will be re-run depending on the grid headers.
- Fixed: Members are captured as they currently are, so the top 10 list is saved, and a ranking isn't done again if the headers change.
You can view or edit the named set from the MDX Calculations screen.
