Hi All,
I am working on ODI mapping where I am calculating" Min(ID) over parition by(device_num, sys_id) as min_id" in expression component, I used another expression component to filter duplicates using row_number over partition by (ID) order by(min_id) this reaults in window function error. followed by a filter "rownum=1"
I understand that I need to run the analytical function on top the aggregate results. I am not sure how to achieve this in odi 12c. can anyone of you please guide me?
ID, DEVICE_NUM, SYS_ID
im trying to achieve
