> 16 fields in an index? Why?

I am not sure if this is correct but since it is a fact table, I need to join constantly to dimension tables through it´s keys. This index is to improve join performance. Any advice here?

Will try.

It is actually 25% now.

> 93 partitions is a lot. Will you be DROPping 'old' partitions eventually?

It increases 10 partitions by month. Since it can hold 1024 partitions, I am not concerned about it. Should I?

Thanks for your help.
