> *Problem:*Fixed below issues in case of pre aggregate
> 1. Pre aggregate data map table column order is not as per query given  by user because of which while data is loaded to wrong column
> 2. when aggregate function contains any expression query is failing with match error
> 3. pre aggregate data map columns and parent tables columns encoder is not matching
> *Solution:*
> 1. Do not consider group columns in pre aggregate
> 2. when aggregate function contains any expression hit the maintable
> 3. Get encoder from main table and add in pre aggregate table column
> When aggregation type is sum or avg create measure column
