Sorry for late reply.
Some of the business users are like to see in that way.
They want to get the fields in a order like, Year->Quarter->Month->Week->Day in the list.
If I expose a list of fields to the business users for adding analysis by their own they would like to get the fields in a order that already they accustomed to see (and also relevant to business needs).
In case of self service BI, the perspective is a bit different.
