Hi @yezhehu
Following calculations work fine without a date filter. However, period-over-period calculations cannot be used with a date filter.
For the Value - Last Month End calculation, used to get the last value of the month is explained in this community post.
Example:
Value on Last Month Same Day - periodOverPeriodLastValue(count({Customer ID}), {Reporting Date}, MONTH, 1)
Difference from Last Month Same Day - periodOverPeriodDifference(count({Customer ID}), {Reporting Date}, MONTH, 1)
