Hi,
I want to have non-standard aggregate measures in OLAP cube. E.g. IRR (internal rate of return). Basically, the measure is a forumla based and not one of the standard aggregates, such as SUM, AVG and COUNT. I am thinking of computing such measures using custom Java code by implementing mondrian.spi.UserDefinedFunction interface. The idea is that formula based measure are not stored in the fact table.
method gives me access to Query, Cube, Measures, Dimensions and current members of each Dimensions. (Actually many other information). The issue I have is to pass date range to this method. In MDX, we can filter records by specifying filter for date dimension, e.g. [Time].[1990]:[Time].[2001]. Can we pass this date range to the Java method?
Thanks,
Chir
