SSAS Row Count Aggregation

Question

Hi I have a table like this:

idCustomer  |    idTime      | idStatus
---------------------------------
    1       |   20010101     |    2
    1       |   20010102     |    2
    1       |   20010103     |    3
    2       |   20010101     |    1
...

I have now added this table as a factless fact table in my cube with a measure which aggregates the row count for each customer, so that for each day I can see how many customers are at each status and I can drill down to see which customers they are.

This is all well and good but when I roll it up to the month or year level it start summing up the values of each day where instead I want to see the last non empty value.

I'm not sure if this is possible but I can't think of another way of getting this information without creating a fact table with the counts for each status on each day and loosing the ability to drill down.

Can anyone help??

An easy way to get what you want would be to convert your factless fact table to one having a fact: the count. Just add a named calculation to the table object in the data source view. Name the calculation like you want your measure to be named, and use 1 as the expression. Then you can define a measure based on this calculation using the aggregate function "LastNonEmpty", and use this instead of your current count measure.
