Program code determines whether a retention base, defined as a property within a disposition schedule has a value, wherein the disposition schedule defines additional properties and instructions for disposal of a record, and wherein the additional properties include a retention period. The program code identifies a change to at least one of the retention base and the retention period. The program code generates a point in time to perform the disposal of the record based on the change that is identified, wherein the disposal is an action defined for a phase of the disposition schedule.
