AverageOfChildren Aggregation function gives error.

Hi

This is a very peculiar problem, and I did not find any entry on the net regarding this.

Background: I have written .Net 2.0 programs that use AMO and create the complete gamut of SSAS 2005 objects at one go. They create Dimensions, Cubes, MeasureGroups, Measures, Partitions....etc. This is working and after processin the objects, they are browsable also.

Now the problem is: When i create a measure, I am not specifying any AggregationFunction (Not even 'None'), but the default aggregation 'SUM' is added automatically.

question 1: Why is this? How to avoid this?

Since I dont want the 'SUM' aggregation for some of the measures, I open BI studio and change one of the measure's aggregation function to 'AverageOfChildren', I get an error as soon as i do this. The measure is now underlined with the curly red (indicating an error). The error msg displayed is: Cube xyz cannot be saved because:

Cube 'xyz' > Measure Group 'abc' > Measure 'def' : Aggregate function AverageOfChildren is not allowed in Standard server edition.

question 2: What is this? Why is this? how to go about further from this?

Is this really because we use the standard server edition? (I dont know which edition we use)

Thanks and Regards

Yes, some functionality is only available in the Enterprise SKU. The BI Studio environment uses a property to allow you to develop targeting a particular SKU (which will change the client-side validation -- the red squigglies). This allows for a visual way to design an Analysis Services database that limits its features to the standard SKU. When the project is deployed, validation is done again by the server.

In general, semi-additive measures are only available in enterprise edition (like AverageOfChildren, LastNonEmpty, FirstNonEmpty and None).

Hope that helps.
