Hi Gurus, i found some threads with a similar question, but couldn't find a easy solution for this.
Background: I have a Huge fact dimension table(table has both measures and dimensions) that i am using to build a SSAS Cube.
The table didnot have a unique identifier, so the database team added ROW NUM as a column to the table which i am using as a PrimaryKey in my Cube build. I was able to create a cube successfully with it without any issues.
Problem: Now customers are asking for a 'Claim Count calculation' which shows the Distinct Claim Count.
Its defined as below :
Count(Distinct Claim_Number || Claim Year || Claim Month)
. All the 3 columns are available in table, but when i am trying to create this Count Distinct Object in the DSV the Cube processing time increased by 5 times, as now i have to use a GroupBy function in my SQL.(There are around 30 columns to group by).
Is there a better way to achieve this Count(Distinct Claim_Number || Claim Year || Claim Month) without using groupBy in DSV SQL logic? I cant seem to find any Count(Distinct) function in the Cube Calculation functions?
Please advise,
Thanks,
Kon
