Cube operator and aggregation of measures on existing records

Question

Hi there,
I'm using a cube operator with loading type LOAD in order to perform merge on fact table.
We have following situation
Record already exists on fact table for customer and product with qty 8.
Incoming record has qty 2, so tried using cube operator hoping that because aggragtion specfied on qty measure was sum and set to solve cube, new qty would be 10.
However, looked at sql generated and record simply gets updated with new qty rather than adding new to existing qty.
I can achieve our aim by simply reading for any existing record and adding new record qty to existing record qty, but was hoping the cube operator would do thi s for me.
Anybody achivede anything similar using sinmply cube operator.
Many Thanks

Do you mean that you want to load the data into the AW using the AVG function instead of SUM? If this is true, are you planning to use AVG as the aggregation operator in the AW as well? Will this give the answer you want? The code currently defaults to SUM for load even if you aggregate the cube using AVG since AVG of AVG is not usually what people want. If you want to do it anyway then there it is possible if you hand edit the XML to add an attribute named AggregationMethod to the CubeMap. E.g.
    <CubeMap
      Name="MAP1"
      Query="SALES_FACT"
      AggregationMethod="AVG">But the simpler way to do it is to define a SQL View that aggregates to the load level using AVG and then map the cube to the view.
