Hello!
I have the following table set up that shows the periods and weeks per period horizontally and the time category vertically. How do you create the three calculations listed:
- TTM with 4 month lag (excluding P9 & P10)
- 4 Week Month (excluding P9 & P10)
- 5 Week Month (excluding P9 & P10)
Assume the periods are associated with the beginning/ending of months in a standard calendar year. Thanks in advance!
