I know it's best practice to avoid multiple levels of lookup tables. However, how is this generally done in practice? I have abbreviated city names coming from the fact table, some of which get consolidate (Baltimore into Washington, D.C., for example). I also want to sort these in situations where I don't want the fields in alpha order. Please see below:
Unique values from fact table on left, desired rollup on rightI want to use this table as a slicer and have the ability to modify the sort order
Any way of doing this without creating two tables?
