I will try to explain more fully what I am trying to do.
I am trying to build a report as an audit check on the daily interest calculation of bank accounts.
I have three primary data providers. There are more, but I don't think that matters at this point.
Calendar - a date for every day within a range of dates
Transactions - transactions for selected account within the same range of dates as the Calendar
Interest Plan - interest plan details
I have created a SQL script to illustrate this here...
