To get to the data from the spreadsheet I need a calculated dimension based on the month end date + another variable to calculate if it is overdue or not.
=IF([ID]='0' orlen([ID])=0,IF(([Created Date]+[Days Forward])>[Month End Date],'on Track','Overdue'))
Then I sum the expression based on the below
if([Function]='Type A',count(distinct[ID]))
I can join the 'Threshold Spreadsheet' to the 'Historical spreadsheet' but I get $Syn which produces the wrong data.
