The Requirement Panel's Filter should be used to reduce the number of work orders displayed in the Requirement Panel by setting filter criteria in the case when the user searches for work orders with existing View and dozens of work orders that don't fit in the Requirement Panel, making it easier for the user to find the right work order. For example, Requirement Panel has “Day of Week” column, and Sunday, 7 kind of values, Sunday, Monday, ... , and Saturday, are in this column. And, let’s imagine that there are dozen of work orders which have Sunday and Monday in Day of Week column. With current behavior, all days of week are shown as Filter criteria on Requirement Panel. I suggest that only Sunday and Monday are shown as Filter criteria on Requirement Panel in the case search results have only Sunday and Monday days of week.
