Im an trying to build a simple report that restricts it data based on a Date. To achieve this i applied a daterange parameter. But not it appears that this always requires you to fill in both ends of the range. e.g. where prep.CompletionDate >=RANGEBEGIN($SaleDate) Is not upheld when you do not fill in the To part of the DateRange. How could you best achieve such a filter without you requiring to always fill in both dates?
