The Start Period and Finish Period lookups when creating a new cost plan in the modern UX window display the date periods only from Jan 1, 2006 – Jan 1, 2008. Is this expected? Can we configure more values to be available for these fields?
This is expected behavior. It is due to a limitation across all lookups in the modern UX.
Users need to type the related text to search for the values that are not present in the first twenty-five results. In this cost plan example, the first 25 results were the monthly periods between January 2006 to January 2008.
At this time, there is no capability to scroll through all values within a lookup across the modern UX. There are no plans to expand this functionality to where all periods will be available on the scroll list as it may result in severe performance issues.
