I am facing issue in calculating past 5 week data based on current date (excluding currrent week) For e.g: Suppose we are in 40th week of this year, I need to get the sum of all the transactions for the previous 5 weeks (39, 38, 37, 36 & 35).
Currently calculating based on the calendar day but as Calendar day is giving the granular level of data, inorder to increase the performance I need to use the calendar week (sample data like (2012/40).
Is there a way to do this?
