I have a report containing three columns: Posting Date, Amount, and Category. Each category consists of B, O, and C.

Basically this column will refresh between 05/01/2013 and 06/15/2013 but not beyond that date. How can I do that? I want all other columns in the report to keep refreshing beyond 06/15/2013. My expression for that specific column is:
