Calculations based on column filtered by SQL query
YEAR("- CustomObject6 Custom Attributes".ZDate_31) IN (YEAR(CURRENT_DATE), YEAR(CURRENT_DATE) - 1)
thereby giving me a column each for payments made in 2012 and 2011
I need to perform calculations (subtract amounts per row comparing both years to get value and percentage changes) and display results in separate columns. How do I do this?
Thanks for any assist.
