Analysis Services Processing

May 12, 2006

There are times when a cube already has the data loaded in it, but you would like to reprocess aggregations.

One example I can think of is if you have re-designed aggregations using usage based optimization.

How do you just re-calc the aggs?

Instead of choosing Process Full, choose Process Index.  Process Index only reprocesses the indexes and aggregates.

For a more detailed article on this topic, there is an excellent article by T. K. Anand.

NULL = 0?

May 11, 2006

Does everyone know that NULL is converted to 0 in Analysis Services before it is used in a comparison in MDX?

If you need to check to see if something is null, don't compare it to null, use the ISEMPTY() function.

Good Luck,
