Hi All,

Please kindly assist me to get the count of distinct claims number for last 12 months-

I am not sure what to put in dimension field -

Currently it is looking like below-

My req- 

sample model attached.

Count(Distinct {<CLAIMS_CAPTURED_MONTH_NAME={">$(=max(CLAIMS_CAPTURED_MONTH_NAME)-100)"}>} [Claims Captured Claim Number])

However, I would use dates as date format not number as you are doing...
