I have a set of history for the past 36 months, one set is the actual history and the other set is the adjusted history.
Not every record exists if he history has not been adjusted.
Essentially i want to use the adjusted history table data if a record exists in there, otherwise want to use the history table.
All records will exist in the History table.
Just want to join the Adjusted history table and the History table to one table using the adjusted history values where they exist and using the history values where no records exist.
